Acute Effect of Aerobic and Strength Exercise on Heart Rate Variability and Baroreflex Sensitivity in Men with Autonomic Dysfunction

The extent to which post-exercise cardiac autonomic control depends on exercise modality remains unclear, particularly among individuals with autonomic dysfunction (CAdysf). This study compared heart rate variability (HRV) and baroreflex sensitivity (BRS) responses to acute aerobic (AE) and strength exercise (SE) in men with CAdysf. Twenty men were assigned into control (n=10: 33.8±3.0 yr; 23.7±1.5 kg/m2) and CAdysf (n=10: 36.2±9.8 yr; 28.4±2.6 kg/m2) groups. CAdysf underwent AE, SE, and a non-exercise control day (CTL) in a randomized, counter-balanced order. HRV and BRS were assessed in a supine position during 25-min of recovery after AE, SE, and CTL. Both HRV indices [P 1.4] and BRS at rest were significantly lower in CAdysf than controls [P < 0.01; Effect size (Cohen's d): ≥ 1.36]. In CAdysf, post-exercise increases in heart rate, sympathetic activity (low-frequency band, LF), and sympathovagal balance (LF:HF ratio), as well as decreases in R-R interval, parasympathetic activity (high-frequency band, HF), and BRS were observed in AE [P < 0.05; Effect size (Cohen's d): ≥ 1.31] and SE [P < 0.05; Effect size (Cohen's d): ≥ 0.79] vs. CTL, but changes were larger after AE than SE [P < 0.05; Effect size (Cohen's d): ≥ 0.73]. In conclusion, both AE and SE elicited post-exercise changes in HRV and BRS among CAdysf men, primarily reflected by lowered vagal modulation, increased sympathovagal balance, and a delayed BRS recovery pattern. However, those changes seem to be more likely to occur after AE than SE.

Trunk muscle activation in the back and hack squat at the same relative loads

The hack squat (HS) is likely to produce a greater 1 repetition maximum (1RM) compared to the back squat (BS). This can be attributed to the support of the trunk during the HS compared to no support during BS. This support however, may compromise trunk muscle activation (TMA), therefore producing different training adaptations. Accordingly, the purpose of this study was to compare 1RM in BS and HS and TMA at 4 relative loads, 65, 75, 85 and 95% of maximal system mass. Ten males completed 3 test sessions:1) BS and HS 1RM, 2) HS & BS neuromuscular test familiarization, and, 3) Neuromuscular test for 3 reps at 4 loads for BS and HS. BS TMA was significantly greater (p<0.05) than HS for all muscles and phases except rectus abdominus in concentric phase. TMA increased (p<0.05) with load in all muscles for both exercises and phases apart from lumbar sacral erector spinae in HS eccentric phase. Mean HS 1RM and submaximal loads were significantly (p<0.0001) higher than the equivalent BS loads. Duration of the eccentric phase was higher (p<0.01) in HS than BS but not different in concentric phase. Duration increased significantly (p<0.01) with load in both exercises and both phases. Despite higher absolute tests loads in HS, TMA was higher in BS. TMA is sensitive to load in both exercises. BS is more effective than HS in activating the muscles of the trunk and therefore arguably more effective in developing trunk strength and stability for dynamic athletic performance.

Agility And Vertical Jump Performances Are Impacted By Acute Cool Exposure

Outdoor sports teams may be exposed to acute cold stress during competition, which may affect performance. Limited research has explored the effects of cold exposure on athletic components. The purpose of this study was to examine the effects of an acute whole-body cool exposure on pro-agility, vertical jump, and sprint performances. Eleven lightly clothed (∼0.3 clo) and not cold acclimatized volunteers (10/1 women/men: age 20.5 ± 0.5 y; height 1.65 ± 0.09 m; mass 63.3 ± 8.9 kg; body fat 21.3 ± 7.6%) completed performance tests in both thermoneutral (17.2°C, 36% relative humidity, Biddeford, Maine, USA) and cool (6.1°C, 72% relative humidity, Thorsmörk, Iceland) ambient temperatures. Prior to completing the performance tests, subjects engaged in a 5 min stretching routine and were subsequently exposed to either a thermoneutral or cool ambient environment for 15 min. Performance tests included three trials of maximal vertical jumps, and two trials of both the 36.6 m sprint and pro-agility tests. Mean performance and lactate values were compared via paired t-tests. Pro-agility completion time was significantly (p<0.05) slower in the cool (5.63 ± 0.33 s) than thermoneutral (5.43 ± 0.26 s) environment. Vertical jump was significantly (p<0.05) lower in the cool (0.36 ± 0.07 m) than thermoneutral (0.41 ± 0.10 m) environment. Sprint performance and lactate values were unaffected by the cool exposure. Brief cool exposure appears to influence agility and vertical jump performances. Our results suggest that it would be prudent for athletes and coaches to consider the ambient environment when preparing for competition.

Reliability and Validity of a New Portable Tethered Sprint Running Test as a Measure of Maximal Anaerobic Performance

Limmer, M, Berkholz, A, de Marées, M, and Platen, P. Reliability and validity of a new portable tethered sprint running test as a measure of maximal anaerobic performance. J Strength Cond Res XX(X): 000–000, 2019—The purposes of this study were to develop a new portable tethered sprint running (PTSR) test for field-based anaerobic performance testing with restricted spatial conditions and the logistical challenge of carrying test equipment, and to determine reliability of the PTSR test. For validity, performance measures were compared with the cycle ergometer Wingate Anaerobic Test (WAnT) power outputs. Twelve recreationally active men and women (24.3 ± 1.6 years; 1.77 ± 0.07 m; 73.3 ± 12.5 kg) performed one familiarization trial followed by 3 randomly assigned experimental 60-second all-out effort trials consisting of one WAnT and 2 PTSR tests. All trials were performed in a randomized order on different days separated by at least 48 hours. Heart rate (HR) and maximum blood lactate concentration were recorded for each experimental trial to determine the physiological responses to the maximal efforts. Correlation coefficients indicated significant relationships between mean force (MF) and peak force (PF) in the PTSR test and mean power (MP) (r = 0.651, p = 0.022) and peak power (PP) (r = 0.877, p = 0.002) in the WAnT, but not for the fatigue index (r = 0.280, p = 0.379). In addition, both PTSR trials showed no significant differences (p > 0.05) between trials and a high reliability for the performance variables MF (intraclass correlation coefficient [ICC] = 0.98, coefficient of variation [%CV] = 7.7), PF (ICC = 0.98, %CV = 8.4), and HR (ICC = 0.92, %CV = 3.1). In conclusion, our results suggest that despite insufficient stimulation of anaerobic metabolism in some subjects resulting from poor implementation of test instructions, the PTSR is a reliable and valid test for an easy and practical assessment of maximal anaerobic performance under different field conditions.

Envelope protein glycosylation mediates Zika virus pathogenesis [Pathogenesis and Immunity]

Zika virus (ZIKV) is an emerging mosquito-borne flavivirus. Recent ZIKV outbreaks have produced serious human disease, including neurodevelopmental malformations (congenital Zika syndrome) and Guillain-Barré syndrome. These outcomes were not associated with ZIKV infection prior to 2013, raising the possibility that viral genetic changes could contribute to new clinical manifestations. All contemporary ZIKV isolates encode an N-linked glycosylation site in the envelope (E) protein (N154) but this glycosylation site is absent in many historical ZIKV isolates. Here, we investigated the role of E protein glycosylation in ZIKV pathogenesis using two contemporary Asian-lineage strains (H/PF/2013 and PRVABC59) and the historical African-lineage strain (MR766). We found that glycosylated viruses were highly pathogenic in Ifnar1-/- mice. In contrast, non-glycosylated viruses were attenuated, producing lower viral loads in the serum and brain when inoculated subcutaneously, but remaining neurovirulent when inoculated intracranially. These results suggest that E glycosylation is advantageous in the periphery but not within the brain. Accordingly, we found that glycosylation facilitated infection of cells expressing DC-SIGN and DC-SIGNR, suggesting that inefficient infection of lectin-expressing leukocytes could contribute to the attenuation of non-glycosylated ZIKV in mice.

IMPORTANCE It is unclear why the ability of Zika virus (ZIKV) to cause serious disease, including Guillain-Barré syndrome and birth defects, was not recognized until recent outbreaks. One contributing factor could be genetic differences between contemporary ZIKV strains and historical ZIKV strains. All isolates from recent outbreaks encode a viral envelope protein that is glycosylated, whereas many historical ZIKV strains lack this glycosylation. We generated non-glycosylated ZIKV mutants from contemporary and historical strains and evaluated their virulence in mice. We found that non-glycosylated viruses were attenuated and produced lower viral loads in serum and brains. Our studies suggest envelope protein glycosylation contributes to ZIKV pathogenesis, possibly by facilitating attachment to and infection of lectin-expressing leukocytes.

Effects of Transcranial Direct Current Stimulation With Caffeine Intake on Muscular Strength and Perceived Exertion

Lattari, E, Vieira, LAF, Oliveira, BRR, Unal, G, Bikson, M, de Mello Pedreiro, RC, Marques Neto, SR, Machado, S, and Maranhão-Neto, GA. Effects of transcranial direct current stimulation with caffeine intake on muscular strength and perceived exertion. J Strength Cond Res XX(X): 000–000, 2019—The aim of this study was to investigate the acute effects of transcranial direct current stimulation (tDCS) associated with caffeine intake on muscular strength and ratings of perceived exertion (RPE). Fifteen healthy young males recreationally trained (age: 25.3 ± 3.2 years, body mass: 78.0 ± 6.9 kg, height: 174.1 ± 6.1 cm) were recruited. The experimental conditions started with the administration of caffeine (Caff) or placebo (Pla) 1 hour before starting the anodal tDCS (a-tDCS or sham). There was an intake of 5 mg·kg−1 of Caff or 5 mg·kg−1 of Pla. After the intake, a-tDCS or sham was applied in the left dorsolateral prefrontal cortex with intensity of 2 mA and 20 minutes of duration. The experimental conditions were defined as Sham + Pla, a-tDCS + Pla, Sham + Caff, and a-tDCS + Caff. After the conditions, muscular strength and RPE were verified. The muscular strength was determined by volume load performed in bench press exercise. The muscular strength in Sham + Pla condition was lower compared with all others conditions (p < 0.05). The RPE in the Sham + Pla was greater compared with a-tDCS + Caff (p < 0.05). The muscular strength was greater in all experimental conditions, and a-tDCS + Caff had lower RPE compared with placebo. When very little gains in muscle strength are expected, both caffeine and tDCS were effective in increasing muscle strength. Besides, the improvement in RPE of the caffeine associated with a-tDCS could prove advantageous in participants experienced in strength training. In fact, coaches and applied sport scientists quantitating the intensity of training based on RPE.

Modeling HIV-1 latency using primary CD4+ T cells from HIV-1 infected ART suppressed individuals [Virus-Cell Interactions]

The small frequency of latently HIV-infected cells in vivo limits the testing of potential HIV cure strategies using cells from successfully suppressed individuals. To date, primary cell models of latency use cells infected in vitro. Primary CD4+ T cell models carrying an individual’s endogenous HIV reservoir that recapitulate in vivo conditions of HIV latency are still outstanding. We developed a primary CD4+ T cell model of HIV latency derived from memory CD4+ T cells isolated from virally suppressed HIV-infected individuals, that recapitulates HIV-1 latency and viral reactivation events. This model is based on the expansion of primary CD4+ T cells up to 300 fold in cell number. These cells reestablish a resting state without active virus production after extended culture and maintain a stable number of total HIV proviruses. The ability of these cells to respond to various classes of latency-reversing agents is similar to ex vivo CD4+ T cells directly isolated from blood. Importantly, viral outgrowth assays confirmed the ability of these expanded cells to produce replication competent endogenous virus. In sum, this model recapitulates ex vivo viral reactivation conditions, captures the variability between individuals with different HIV reservoir and provides large numbers of cells for testing multiple agents from a single donor. The use of this novel model will allow accurate exploration of novel cure approaches, either aimed at promoting viral reactivation or maintenance of sustained latency.

Importance: Primary cell models of HIV latency have been very useful to identify mechanisms contributing to HIV latency and to evaluate potential HIV cure strategies. However, the current models utilize in vitro infection with exogenous virus that do not fully recapitulate virus reactivation profiles of endogenous HIV in in vivo infected CD4+ T cells. In contrast, CD4+ T cells from HIV-infected individuals require leukapheresis to obtain sufficient amounts of cells to interrogate the HIV reservoir in vitro. In the model we propose here, in vitro expansion and extended culture of primary CD4+ T cells isolated from virally suppressed HIV-infected individuals enable obtaining large numbers of cells harboring endogenous latent HIV reservoir without performing leukaphereses. This model captures the variability of HIV reservoir seeded in different individuals and should be useful to evaluate future HIV cure strategies.

10 Best Drone Bundles of 2019

This page reviews 10 DJI drone bundles. They’re popular because they can save money, time, and frustration. Best of all is that quadcopter kits, bundles, and Fly More combos vary to meet pilots wants and needs. They are convenient because buyers get to checkout with everything they need in one go. It’s less frustrating than searching for items one by one hoping everything is in stock.

What to Look for in a Drone Bundle

Anyone familiar with my guides will know that I’m a huge fan of the checklist. It’s the most straightforward approach for making better buying decisions. Your list of items has two sections. One column is for needs (must-haves) and the other for wants (would like). It’s a simple approach that ensures you checkout with everything you need and some of what you want.

Here’s an example of what a drone bundle shopping list might look like:

Quadcopter Drone w/ 4K camera
3-axis stabilizing gimbal
Remote controller
3 flight batteries
Battery charger
Extra set of props
USB adapter
12-month factory warranty
Hard carrying case
Car charger
MicroSD card
Done landing pad

There should be enough drone bundles to meet most if not all your needs. Your list may change as you start to review the options and that’s normal. The point is to get something down so that you have a starting point. It’s a guaranteed stress-free way to shop for your quadcopter and accessories.

Drone Companies that Offer Bundles

DJI is the most prominent company to offer drone kits, bundles and combos. That’s because there are so many accessories to support its popular models. Smaller companies can also provide exclusive deals by offering extra items with their drones. These are not like the beefed-up DJI Fly More Combos, though. Smaller deals may include things like spare props, bonus batteries, and a carrying case, etc.

Careful what You Buy

Try not to let the hype suck you in with an impressive display of goodies. It can be tempting, I know. My advice is to pause for thought before you buy anything. If the items in the bundle didn’t make your list (see above), do you need or even want them? There’s nothing worse than paying for a bunch of stuff you never use. Most of us have done it to some degree, only to regret the decision later.

To summarize: a bundle is only excellent value if it meets the following criteria:

  1. You WILL use most if not all the items it includes
  2. Bundled items are the same price or cheaper than their individual costs

The perfect drone bundle has all that you demand and nothing you don’t. But what if it has everything you need, most of what you want, and a few things you can’t use? Well, it may still offer excellent value if the things you don’t want or won’t use are low-cost items. A cable of some kind or a landing pad are two examples. Again, stay as close to your list as possible.

Drone Buying Tips

OK, so you’ve listed all your bundle needs and wants. You’re now ready to browse the options if you already know what drone to choose. If not, then here’s a quick list of things to get you thinking:

  • Set a maximum budget
  • Size & design, e.g., big & stable, travel-friendly, foldable, pocketable?
  • Camera resolution and capability
  • Flight features and modes that meet your needs
  • Max flight time on a single charge
  • Battery charging times
  • Cost of extra batteries
  • Control range (distance)
  • Anything else you can think of

Don’t overthink the finer details yet. Make a crude list to start with and modify it as you learn about the different drone options available.

7 Best Small RC Boats for Kids and Adults

Radio controlled boats are as popular today as they’ve ever been, and more affordable. They also have better technology and handling than those of yesteryear. This guide focuses on smaller RC boats and mini-sized vessels. The great thing about smaller models is their broad appeal. Most are easy to use and some can safely cruise in bathtubs and pools as well as ponds and rivers.

What to Expect from Smaller RC Boats

Smaller RC boats are no different from their larger counterparts in that you get what you pay for. You also need to know what you want from the model. There’s no need to spend more than a few dollars if it’s a simple toy for a toddler. However, consider a few failsafe features if you expect to use it on ponds, rivers, and lakes. The purpose of this guide is to help you make the best decision in any case.

Here are some typical characteristics to look out for on RC boats:

  • Size of the boat (always check the product dimension)
  • Type of RC craft, e.g., speedboat, ship, fishing, yacht, etc.
  • Remote control functions
  • Control range (distance)
  • Battery life or playing time
  • Charging time
  • Anti-flip hull
  • Capsize recovery mode
  • Out of range and low battery alarms

A simple list like this ensures you choose the right model. Not everything will apply to all people. Feel free to modify the above points so that it’s closer to your specific needs and wants.

Realistic Expectations

One of the most common shopping blunders with any RC model is to overlook its size. Product images can easily draw shoppers in, but they don’t represent the true measurements. We know this from the feedback users leave in review sections. They’re surprised at how big or small a product is because they overlooked scale sizes or dimensions. I add the dimensions for each boat in the reviews.

There’s isn’t a maximum size for a small boat because they’re comparisons. For example, a 1/12 scale model of a rowing boat is sure to be much smaller than a 1/12 scale model of a cruise ship. There are no ‘size’ surprises in these reviews providing you check the quick specs table.

Consider the RC boat’s construction. Parents of small children are sure to want a product that uses non-toxic plastics. Check for crash-resistant properties too. Control range shouldn’t be that vital for smaller RC boats. After all, there’s no fun if it goes out of the line of sight (LOS). The playing time (battery life) is something to ponder, as are charging times and the cost of spare batteries.

The Importance of Failsafe Features

Even some of the cheaper RC boats come with failsafe features that can prove invaluable. An anti-tilt hull reduces the risk of capsizing. And capsize recovery modes flip boats back upright if they do overturn. That means no lost boats or wading/swimming out to rescue an upturned model. Out of range warnings and low-battery alarms prevent vessels becoming stranded on larger bodies of water.

About My ‘Small RC Boats’ Guide

There are 7 reviews on this page for small RC boats. I selected these products after revising dozens of models. I also took the opinions of industry experts into consideration along with real user feedback. The final picks cover all types of mini RC boats and price ranges. I’ve highlighted the above features and specs with models that have them. Likewise, I also point out areas where a product may fall short.

1. Geburun Electric High-Speed RC Boat | Best Budget

Geburun Electric High-Speed RC BoatView on Amazon

Editor’s Rating: 4.7/5

The Best Budget pick goes to the Geburun Electric High-Speed RC Boat. It’s one of the larger small models here and best suited for outdoor use. It’s fast too and crash-resistant.

  • Best feature 1: Impact-resistant ABS material
  • Best feature 2: Easy, USB charging
  • Plus points: Safety prop, fast top speed, large torque double propellers, decent range
  • Minus points: Slow charging, average playing time

Reasons to Consider the Geburun High-Speedboat

The Geburun RC racing boat uses harmless, high-quality impact-resistant ABS in its build. Another safety feature is that the motor and paddle won’t work until they contact water. This is a powerful toy model for its price category with dual motors and high-torque props. Users can expect speeds of up to 12 mph (20 km/h) in calm weather. The control range is a decent 164 ft. (50 M).

Charging the battery is easy thanks to the boat’s USB port. That sounds logical, but USB charging is not something all RC models offer, so it’s a welcome feature. Charging time is less impressive.

The Not So Good

Battery charging takes up to 3 hours for 15 minutes of playing time. That means extra batteries are essential for anyone who wants uninterrupted fun on the water.


Tech Specs
Maker’s Recommended Age: 12+ years
Dimensions: 17.6 x 6.2 x 4.8”
Product Weight: 14.1 oz.
Top Speed: 12.4 mph (20 km/h)
Max Range: 164 ft. (50 meters)
Battery: 4.8V 700mAh
Max Running Time: 15 minutes
Charging Time: 3 hours
The Pros
Impact-resistant ABS material
USB charging port
Safety prop (only works underwater)
Large torque double propellers
Fast top speed
Decent control range
The Cons
Average playing time
Slowish charging time

2. USA Toyz Udi001 Venom Small RC Boat | Best Value

USA Toyz Udi001 Venom Small RC BoatView on Amazon

Editor’s Rating: 4.6/5

Best Value small RC boat goes to the popular FORCE1 Power Venom Udi001. Its sleek design and anti-tilt waterproof ABS hull slices through the water with speed and ease.

  • Best feature 1: Anti-tilt ABS hull
  • Best feature 2: Capsize recovery mode
  • Plus points: Easy to steer, sturdy build, fast, bonus battery, low battery alarm, emergency stop
  • Minus points: No out of range alarm, average running time

Reasons to Consider the Small Udi001 Venom Boat

Self-righting boats flip far less than models without anti-tilt hulls, but they can still overturn. It’s why a capsize recovery mode is so vital for those who play on big ponds, lakes, and rivers. This boat has it, so hobbyists can race with confidence. The Udi001 Venom is easy to steer and sports a sturdy built to protect it against knocks and collisions. It’s fast too, reaching speeds up to 15 mph (24 km/h).

Safety features include a low battery alarm and an emergency stop function. Its low-battery warning gives out an audible beep as soon as it reaches its final minute of power. That’s ample time to return the boat. The bonus battery (2 total) effectively doubles the playing time. Always allow a few minutes for the motor to cool down between battery swaps.

The Not So Good

There isn’t an out-of-range warning alarm with the Udi001 Venom. Users must remember to stay within range to prevent the boat disappearing for good. The running time is 15 minutes, so extra batteries are vital to avoid waiting 90 minutes between charges.


Tech Specs
Maker’s Recommended Age: 14+ years
Dimensions: 4.3 x 15 x 5.5”
Shipping Weight: 2.2 lbs.
Top Speed: 15 mph (24 km/h)
Range: 300 ft. (91 meters)
Battery: 3.7v 600mAh Li-Ion
Max Running Time: 15 minutes
Charging Time: 90 minutes
Controller: 2.4GHz Transmitter
The Pros
Anti-tilt ABS hull
Capsize recovery mode
Easy to steer at the entry-level
Sturdy build
Fast top speed
Bonus battery
Low battery alarm
Emergency stop function
The Cons
No out of range warning
Average running time

3. Aquacraft Mini Alligator Tours RC Airboat | Top Pick

Aquacraft Mini Alligator Tours RC AirboatView on Amazon

Editor’s Rating: 4.5/5

My Top Pick is not your typical RC water vessel. Meet the Aquacraft Mini Alligator Tours RC Airboat. It’s the biggest of the small boats in this guide and one that has a unique appeal.

  • Best feature 1: Flat-bottom ABS hull
  • Best feature 2: Durable injection-molded cage
  • Plus points: Realistic design, powerful motor, easy to steer, large air rudders, magnetic hatch
  • Minus points: Average playing time, no warning alarm

Reasons to Consider Aquacraft Mini RC Airboat

The best thing about an airboat is its ability to glide across shallow water. That means you can take it to places other RC boats can’t go. A stable flat-bottom ABS hull offers a thrilling experience and a unique type of adventure. The Mini Alligator comes with an injection-molded cage to protect the user. The cage also shields the spinning prop and powerful 380-motor from damage.

Airboats are more agile and easier to steer than speedboats and other vessels in calm weather. And the large twin air rudders mean there are no concerns about underwater obstacles. Another positive is that the battery’s easy to access and quick to swap thanks to the magnetic hatch.

The Not So Good

The playing time is 15 minutes which is standard for this type of RC vessel so consider extra batteries. Charging times with the 12V DC charger can vary depending on the source. The biggest gripe with this otherwise impressive airboat is the absence of alarms. No low-battery or out-of-range signals mean users must be extra vigilant on larger bodies of water like rivers and lakes.


Tech Specs
Maker’s Recommended Age: 15+ years
Dimensions: 18.25 x 7.25 x 7”
Product Weight: 24.6 oz.
Top Speed: 10+ mph (16 km/h)
Range: Not specified
Battery: 7.2 V 6 cell NiMH
Max Running Time: 15 minutes
Charging Time: Not specified
Controller: Tactic TTX300 Transmitter
The Pros
Flat-bottom ABS hull
Injection-molded cage
Realistic design
Easy to steer
Powerful motor
Large air rudders
Magnetic hatch
The Cons
Average playing time
No warning alarm

4. Unetox Mini High-Speed RC Racing Boat

Unetox Mini High-Speed RC Racing BoatView on Amazon

Editor’s Rating: 4.3/5

The Unetox Mini is a small-scale RC racing boat primarily for kids. It makes an ideal toy for younger children who are not ready for too much oomph on the water.

  • Best feature 1: Easy to operate, 4 channel controller
  • Best feature 2: Self-righting feature
  • Plus points: Small size, solid ABS material, full drive functions, decent range
  • Minus points: No batteries included, no alarms, short playing time, slow

Reasons to Consider Unetox Mini RC Racer

This ABS plastic model really is a mini at just 5.12” (13 cm) long. Its bright orange color catches the attention of young skippers and makes it easy to see on the water. The Unetox Mini is ideal for close range use like pools and small ponds. The remote provides full controls, i.e., forward, backward, left and right turns. There’s even a self-righting feature to flip the tiny craft upright if it capsizes.

The control range is 98 ft. (30 M) which gives young captains plenty of room to play. The makers suggest it’s suitable for those 8 years and older. I think it’s a better choice for younger children under adult supervision. Older kids will soon get bored with the small size and slow speeds (see below).

The Not So Good

The Unetox Mini is a budget-priced toy with limited functions. There aren’t any battery or range alarms which is a shame. That makes it more suitable for toddlers in the pool rather than teens by the lake. The playing time is also short at just 7–8 minutes max.


Tech Specs
Maker’s Recommended Age: 8+ years
Dimensions: 5.11 x 1.69 x 1.96”
Product Weight: 11.4 oz.
Top Speed: 2.2 mph (3.6km/h)
Range: 98 ft. (30 meters)
Battery: 3 x AA (not included)
Max Running Time: 7 minutes
Controller: 2.4Ghz transmitter
The Pros
4CH controller (transmitter)
Self-righting feature
Small size
Solid ABS material
Full drive functions
Decent range
The Cons
No warning alarms
No batteries included
Short playing time

5. Tipmant Mini Military RC Aircraft Carrier

Tipmant Mini Military RC Aircraft CarrierView on Amazon

Editor’s Rating: 4.2/5

This Tipmant boat is for those who want to move away from the popular speedboats. It’s a military RC aircraft carrier at the budget end that appeals mostly to younger children.

  • Best feature 1: Simple remote control functions
  • Best feature 2: Water detection safety feature
  • Plus points: Ideal for pools and ponds, built-in battery, fast charging time
  • Minus points: Limited appeal, short playing time, no speed setting

Reasons to Consider the Mini Aircraft Carrier

Tipmant’s Mini Military Aircraft Carrier is an affordable toy-grade RC ship for first-timers. It has some nice details to capture the imagination of youngsters. The remote is super easy to use with simple forward, backward, left, and right controls. Worth noting is that some reviewers report the antenna is missing from the remote—it’s not. This small RC ship sails just fine without one.

The safety features are the same as any other radio-controlled boat. That is, no moving parts work until the model detects water. Likewise, the craft automatically stops when it leaves the water. It’s the perfect vessel to use in pools and other small areas. Users can recharge the built-in boat battery via the controller which only takes a few minutes.

The Not So Good

The Mini Military RC Aircraft Carrier is a budget-end toy with limited functions. It’s unlikely to appeal to kids over 8 because of the above. It’s an ideal model for pools but not so suitable for bathtubs as it’s too zippy and there’s no speed setting. Playing time on a single charge is around 8 minutes.


Tech Specs
Maker’s Recommended Age: 8+ years
Dimensions: 7 x 3.5 x 3”
Product Weight: 2.2 oz.
Range: 50 ft. (15 meters)
Battery: 2.4 V 100mAh Lithium
Max Running Time: 8 minutes
Charging Time: 12 minutes
Controller: 2.4Ghz transmitter
The Pros
Simple control functions
Water detection safety feature
Ideal for pools and bathtubs
Built-in battery
Super-fast charging time
The Cons
Short playing time
Short control range

6. POCO DIVO Vector28 Mini Pool Racing Boat

POCO DIVO Vector28 Mini Pool Racing BoatView on Amazon

Editor’s Rating: 4.3/5

This is the POCO DIVO 2.4Ghz Vector28 Ready-to-Run (RTR) Pool Racer. It’s a high-speed mini racing boat with an ultra-sleek design and plenty of wave-making oomph.

  • Best feature 1: Ready-to-Run (RTR) speedboat
  • Best feature 2: Rubber sealed hull cover
  • Plus points: Affordable, full function control, fast, decent range, low battery alarm
  • Minus points: No out of range alarm, long charging time

Reasons to Consider the Vector28 Mini Pool Boat

The Vector28 Mini Pool speedboat can sit on the palm of a hand, but what it lacks in size, it makes up for on features. A rubber-sealed hull keeps the water out of this surf-slicing racer as it zips across the waves. Its deep-V design drives as well on lakes and ponds as it does in pools despite the name. A powerful 180A brushed motor propels this affordable toy to a top speed of 20+ mph (32 km/h).

Other attractions are the ease-of-use, full controls, and a decent 300 ft. (91 M) control range. The boat also has a low battery alarm that tells users when it’s time to return to port.

The Not So Good

The Vector28 Mini has an impressive control range for a toy RC boat yet no out-of-range alarm. It also has a decent run time for a model in its class that’s let down by the long 3 hour charging.


Tech Specs
Maker’s Recommended Age: 14+ years
Dimensions: 10.88 x 2.85 x 2.2”
Product Weight: 6.2 oz.
Top Speed: 20 mph (32 km/h)
Range: 300 ft. (91 meters)
Battery: 7.4V 360mah LiPo
Max Running Time: 20 minutes
Charging Time: 3 hours
Controller: 2.4Ghz transmitter
The Pros
Ready-to-Run (RTR) speedboat
Rubber sealed hull cover
Full function control
Affordable model
Fast on the water
Decent control range
Low battery alarm
The Cons
No out-of-range warning
Long charging time

7. Waterproof Remote Control 4WD Mini Car Boat

Waterproof Remote Control 4WD Mini Car BoatView on Amazon

Editor’s Rating: 4.5/5

Last on this list is an RC boat—well sort of—with a twist. Meet the waterproof, 4WD mini car boat. It’s a double-sided amphibious model that entertains kids as few toys can.

  • Best feature 1: Drives on land and water
  • Best feature 2: 360° spins & flips
  • Plus points: Fast and powerful, multi-terrain, long range, anti-vibration, non-toxic materials
  • Minus points: Fiddly to charge, long charging time

Why Consider the FREE TO FLY 4WD Mini CarBoat?

The fantastic thing about the Double-Sided 4WD RC Car Boat is its off-road, on-water capabilities. Imagine the fun kids have racing these amphibious robots when they have one each. The boats on this page all have full function controls—for boats. But what they can’t do is perform 360° flips and spins like this fun-loving model. Nor can they turn upside down and keep going.

Experience off-road, multi-terrain capability that’s off the charts. You can take this CarBoat across the grass, sand, on marshy ground, and over water. It’s anti-vibration and crash/abrasion-resistant structure lets users bash with confidence wherever they are. And the non-toxic materials reassure parents that the product is as safe as it is fun.

The Not So Good

The mini car-boat looks fantastic and provides lots of entertainment though it’s not perfect. Running time is average at 15 minutes, but the charging lets it down. You must undo a screw to access the battery each time, which is a design flaw and a hassle. Charging time takes 2+ hours.


Tech Specs
Maker’s Recommended Age: Parental discretion
Dimensions: 9 x 8 x 4”
Product Weight: 2.41 lbs.
Top Speed: 16 mph (25.7 km/h)
Range: 197 ft. (60 meters)
Battery: 6V 400mAh rechargeable
Max Running Time: 15 minutes
Charging Time: 2+ hours
Controller: 2.4GHz transmitter
The Pros
Drives on land and water
Drives on both sides
Dual motors
360° spins & flips
Fast and powerful
Multi-terrain capable
Long range
Anti-vibration mechanism
Non-toxic ABS material
The Cons
Fiddly to charge
Long charging time

5 Best 27-Inch Monitors of 2019

If you want a monitor that offers good screen real estate but doesn’t take up a significant amount of desk space, check out the best 27-inch monitors. They are suitable for both productivity and gaming and are much better for multitasking than smaller monitors, especially those featuring a 4K or QHD resolution. Moreover, they look good whether you sit less than three feet from the screen or from around three to four feet away.

However, since there are a lot of options on the market, shopping for 27-inch monitors is a difficult task, especially if you prefer an all-around monitor that works great for office work, gaming, and general use. We’ll make things easier for you. In this guide, we have compiled the top products currently out, from a couple of 4K monitors to a VA monitor.

1. Best Pick: Acer Predator X27

Acer Predator X27View on Amazon

Editor’s Rating: 4.6/5

If you want the best of the best and can spend around $1,800 on a monitor, the Acer Predator X27 is the best option currently on the market. It’s an extremely expensive product loaded with features, including G-Sync and HDR. It’s got a 4K resolution and a 120 Hz standard refresh rate, the latter of which is notable since almost all 4K monitors on the market are limited to 60 Hz.


An IPS monitor with a 16:9 aspect ratio, the X27 has a subtler design compared to other gaming monitors under the Acer Predator brand, featuring an all-black chassis with narrow bezels and a set of removable blinders for glare reduction. The chassis is quite thick, which means it will stick out more when mounted on the wall. The monitor has built-in speakers, but they are not as good as external speakers and headphones, especially concerning the bass output.

For menu control, this Acer monitor has a small joystick at the back, on the lower-left corner, with a set of clickable function buttons positioned vertically above it. While the control scheme is user-friendly, the joystick and buttons are not easy to access when the blinders are attached. If you want to mount the monitor to a wall mount or a different stand, there is a VESA mounting interface at the back, but you’ll need to use the supplied VESA mount adapter.


One of the more notable downsides of G-Sync monitors is their limited input options, and the X27 is no exception, only offering one DisplayPort and one HDMI port for input, with the G-Sync feature limited to the former. You can use this monitor for PS4 Pro and Xbox One X gaming since the lone HDMI port supports a 4K resolution at 60 Hz. The input ports are down-facing at the rear, along with the analog audio out port.

The X27 also features a USB hub composed of four USB 3.0 downstream ports, one of which supports fast charging, which is convenient. The four USB ports are separated into two pairs, with one pair on the monitor’s left edge for quick access and one pair outward-facing at the back.


The monitor stand is well built, easily supporting the monitor with no major wobbling issues. It has basic cable management in the bottom section and a carrying handle at the top, which is useful when moving the monitor to a different location.

Regarding adjustment options, the stand is decent but not on par with the Dell professional monitors in this guide. You can adjust the height and tilt and swivel the screen, but you can’t rotate the screen to a portrait orientation, which might disappoint some of you. If you want a more flexible setup, you’ll need to mount the monitor to a third-party stand with better ergonomics.


The X27 is an outstanding all-around monitor that works great for gaming, office work, and general use, featuring wide viewing angles and excellent color accuracy. Once fully calibrated, the monitor boasts near-perfect coverage for both Adobe RGB and sRGB color spaces, which is great for color-critical work such as photo editing and graphics design. Whether the monitor is operating in standard mode or HDR mode, the peak brightness is great, most especially for the latter.

One of the few certified DisplayHDR 1000 monitors – the highest level in the HDR standard created by VESA – the X27 offers good performance in HDR mode. It can display a wider range of colors and can get extremely bright, easily reaching 1000 nits peak brightness. The contrast ratio is not that great, though, especially compared to VA monitors.

For gaming, this 4K monitor is excellent, whether you game on PC or consoles. It has a fast response time and a good input lag even when running in 4K resolution. As mentioned, the standard refresh rate is 120 Hz, which translates to increased smoothness in gaming, but if that’s still not good enough for you, there is an option to overclock to 144 Hz. The monitor is most suitable for graphically intensive games such as The Witcher 3: Wild Hunt. If you game on PC with G-Sync enabled, the monitor output stays smooth even when the graphics card output is erratic.


If money is not an issue for you, the X27 is the best 27-inch monitor that you can get right now, most especially if you want an all-around unit that works great for gaming and productivity. It’s an absolute beast, offering a tantalizing list of features. The picture quality is great while the gaming performance is excellent.


Tech Specs

Unimpressive contrast ratio

2. Best Budget: Dell P2719H

Dell P2719HView on Amazon

Editor’s Rating: 3.8/5

If you want a budget-friendly product, there are a number of options out there, many of which feature an IPS panel with a 1920 x 1080 (FHD) resolution. Out of all of them, the Dell P2719H is the best option, featuring a fully adjustable stand and a USB hub – a pair of features not usually associated with budget monitors. You can get it for just around $200-250, with the price sometimes dipping below $200 during a sale.


Like other Dell P-Series and UltraSharp monitors, the P2719H has a professional design, featuring a minimalist chassis that’s notably thinner compared to our top pick. The screen, which has an anti-glare coating, is surrounded by thin bezels at the top and sides, with the company logo sitting in the middle of the thicker bottom bezel. There is a 100 x 100 mm VESA mounting interface at the back, positioned in the central area.

The control buttons are located on the bottom-right of the monitor, on the underside, which is a common setup for most Dell monitors. They are easy to use and produce good tactile feedback when pressed, although some of you might find them too small. The on-screen display (OSD) is similarly well implemented, featuring an organized layout with lots of options.


For video input, this Dell monitor has one HDMI port, one DisplayPort, and one VGA port, the latter of which is useful if you want to connect to older computers. All input ports are down-facing at the rear, along with a pair of USB down ports and the accompanying upstream port. There is another pair of USB ports conveniently placed on the monitor’s left edge. Unlike most monitors, there is no analog audio out on this unit.


One of the best aspects of Dell professional monitors is their great stand design, and that also extends to this particular model. Featuring a simple flat base with a relatively small footprint, the monitor stand is sturdy and offers full adjustment options.

You can adjust the height, tilt, swivel, and pivot to portrait mode, with good adjustment ranges for the former three, especially regarding the swivel range. There is a round hole in the stand for basic cable management and a quick-release button just below where the stand connects to the monitor – both are common features among Dell office monitors.


The P2719H is a professional monitor that works great for general office work, including typing and editing spreadsheets. The color accuracy is good while the viewing angles are great, the latter of which is a staple for IPS monitors. The peak brightness is decent as well, which, combined with the anti-glare screen coating, allows the monitor to work well in a bright room.

While the large screen is good for multitasking, some of you might find the low pixel density – which is due to the common 1920 x 1080 resolution – disappointing, especially if you sit very close to the screen. On a related note, this monitor is not the most suitable for photo editing since the 1080p resolution is a limiting factor.

Since it has thin bezels, this monitor is great for a multi-monitor setup, with its common 100 x 100 mm VESA mounting interface and quick-release stand allowing for easy integration into a multi-monitor arm or wall mount. You can’t use it as a primary or intermediary monitor in a daisy chain setup, though, since it lacks a DisplayPort Out.


Overall, the P2719H is a great product and is a much better option than all those cheap 27-inch IPS monitors selling for less than $200. It has good picture quality, comes with a fully adjustable stand, and offers good connectivity, with the latter two aspects easily separating it from most other budget options.


Tech Specs
Resolution: 1920 x 1080
Refresh Rate: 60 Hz
Response Time: 5 ms
Panel: IPS
Input: DP, HDMI, VGA
Weight: 14.7 lb
The Pros
Good color accuracy
Wide viewing angles
Decent peak brightness
Fully adjustable stand
Good connectivity
Very thin bezels at three sides
The Cons
Low pixel density
Subpar contrast ratio

The LG 27UK650-W is a well-rounded 4K monitor that works great for productivity, watching movies, and gaming on both PC and consoles. It has AMD FreeSync technology, supports HDR content, and offers multiple input options. You can get it for around $400-450, which is a more than reasonable price point considering what the monitor brings to the table.


An IPS monitor with a 60 Hz refresh rate, this LG unit has a minimalist design similar to that of most other LG monitors, featuring thin bezels at three sides and a clean back panel. There is a 100 x 100 mm VESA mounting interface at the back and a small joystick at the bottom for menu control. The screen has an anti-glare coating, which reduces glare when using the monitor in a bright room.

Although the monitor is mostly made of plastic, the build quality is good. There are no speakers on this monitor, which is not really a deal-breaker since monitor speakers tend to sound poor and are not suitable for both gaming and watching movies.


Compared to our budget pick, the 27UK650-W is slightly inferior regarding connectivity, but only because there is no USB hub. For video input, it has one DisplayPort and two HDMI ports, all of which support a 4K resolution with a 60 Hz refresh rate.

Since the HDMI ports support the full refresh rate when running in 4K resolution, this display is suitable for both PS4 Pro and Xbox One X consoles. All input ports are outward-facing at the back, along with the analog audio out port, which makes them easy to access even when the monitor is in a wall-mounted setup.


The monitor stand is similar to the stand of most LG monitors, featuring a crescent-shaped base with a wide footprint. It supports the monitor well, features basic cable management, and offers decent ergonomics, with options to tilt, pivot, and adjust the height. You can’t swivel the screen, though. If you want a more flexible setup, you’ll need to mount the monitor to a fully adjustable third-party monitor arm or wall mount.


The 27UK650-W is a superb all-around monitor with excellent color accuracy, good viewing angles, and good peak brightness. You can use it for different kinds of work and applications, including photo editing, graphics design, computer-aided design (CAD) software, research, and content writing, among other things. It’s great for multitasking with multiple windows open at the same time, thanks to the large screen and high resolution.

On the other hand, the monitor has a subpar contrast ratio, which is a common issue among IPS monitors regardless of the price range. Furthermore, the HDR performance is unimpressive, especially compared to our top pick. While it supports HDR content, the monitor is not fully equipped to properly display HDR content. You can think of it as an entry-level HDR monitor, which can be said for other HDR monitors selling for less than $1,000.

Featuring a fast response time and a low input lag, the 27UK650-W is a brilliant monitor for gaming on both PC and consoles. It’s great for single-player games with gorgeous or stylish visuals, such as Final Fantasy XV and The Witcher 3: Wild Hunt. The monitor also features FreeSync, which synchronizes the monitor refresh rate to the graphics card output – an especially beneficial feature when playing graphically intensive games. Moreover, FreeSync is supported over both DisplayPort and HDMI inputs, which is good news if you game on Xbox One X.


In all, the 27UK650-W is a fantastic monitor that offers excellent value for the money, boasting great picture quality and good gaming performance. It has a 4K resolution, which is great for regular gaming, media consumption, and art-related work, and comes with an adjustable stand. If our top pick is way out of your budget range but you still prefer an all-around 4K monitor, go for this LG product instead.

4. Dell U2717D

Editor’s Rating: 4/5

One of the best monitors for daisy chaining, the Dell U2717D is a professional monitor designed for productivity, featuring a 1440p (QHD) resolution and a fully adjustable stand for easy screen position adjustments. You can get it for just around $350, which makes it significantly more affordable than all those 27-inch QHD IPS monitors built for gaming.


An IPS display, the U2717D is not that different from our budget pick and other UltraSharp monitors regarding design. It has a minimalist profile, with thin bezels all around and a plain back panel. The screen has an anti-glare coating for glare reduction. For menu control, there is a set of physical buttons located on the bottom-right corner of the monitor. They are easy to use but are not as intuitive as the control scheme of the LG 27UK650-W.

The monitor has a 100 x 100 mm VESA mounting interface at the back, which is useful if you plan to mount the monitor to a wall mount to save desk space. Like most other Dell office monitors, there are no internal speakers on this unit. As expected from a Dell product, the U2717D has a good build quality and doesn’t feel cheap despite the plastic parts.


Of the best 27-inch monitors in this guide, the U2717D offers the most connection options, featuring one HDMI port, one DisplayPort, one Mini DisplayPort, one DisplayPort Out, one audio out, and four USB 3.0 down ports. The USB ports are separated into two pairs: one pair is located on the monitor’s left edge for quick access while the other pair is down-firing at the rear, along with all the other connection ports.

The Mini DisplayPort is for connecting the monitor to a compatible laptop. The DisplayPort Out is for daisy chaining multiple monitors, which makes for a clutter-free multi-monitor setup where only one monitor is directly connected to the computer.


Like with our budget pick, the monitor stand is sturdy and offers full adjustment options, with similar adjustment ranges. You can adjust the height, tilt, swivel, and pivot to portrait mode, the latter of which is beneficial for coding and reading long documents. The stand has the familiar cable management hole typically seen in Dell monitors. If you want to remove the stand for wall mounting, there is a quick-release button right below where the stand connects to the monitor.


The U2717D is best used for productivity and works great in a typical office setting with lots of light sources, thanks to the anti-glare screen coating and the good brightness rating. It has excellent color accuracy and wide viewing angles, with the former being most beneficial in photo editing, graphics design, and other color-critical work. The monitor has a higher resolution than the Dell P2719H, which translates to more detailed images and sharper texts.

If you are building a multi-monitor setup, the U2717D is a recommended monitor. It has thin bezels at the sides, which is great if you care about aesthetics. More importantly, it has a DisplayPort Out, which allows it to be a primary or intermediary monitor in a daisy-chained multi-monitor setup. You can pair it with another 1440p monitor or with a couple of 1080p monitors, provided the refresh rates of all units involved is 60 Hz.

For gaming, the U2717D is not the most ideal option. If you mostly play story-driven or slow-paced games and care more about picture quality than fast response times and high refresh rates, this monitor is decent enough. But if you mostly play fast-paced games or are into competitive gaming, there are much better options out there.


Overall, the U2717D is a recommended product if you are in the market for a 27-inch QHD monitor with an IPS panel. It’s great for productivity, especially if you like to work with multiple open windows at the same time. While not as versatile as the Acer Predator X27 and the LG 27UK650-W, the U2717D gets the job done and is perfect for office use, especially if you are going for a multi-monitor setup.


Tech Specs
Resolution: 2560 x 1440
Refresh Rate: 60 Hz
Response Time: 6 ms
Panel: IPS
Input: DP, HDMI, Mini DP
Weight: 15.4 lb
The Pros
Great color reproduction
Wide viewing angles
Good peak brightness
Fully adjustable stand
DisplayPort Out for daisy chaining
USB hub with fast charging
The Cons
Subpar contrast ratio
Mediocre black uniformity

5. Samsung C27HG70

Samsung C27HG70View on Amazon

Editor’s Rating: 4.1/5

The Samsung C27HG70 is the best option if you want a 27-inch VA monitor suitable for gaming, watching movies, and productivity. It has a QHD resolution and a 144 Hz refresh rate, which is the highest non-overlocked refresh rate among the monitors in this guide. You can get this monitor for around $450-500, which makes it more expensive than the Dell U2717D.


The C27HG70 is unique among the monitors on this list, featuring a curved screen with a curve radius of 1800R, which means the curvature is more pronounced. It has narrow bezels at all sides and includes a cool lighting system at the back. While the monitor has a VESA mounting interface (100 x 100 mm), you can’t mount it to a wall mount or monitor arm just like any other monitor. You need to use the included VESA mount adapter since the monitor has a different mounting interface.

Like the Acer Predator X27, this Samsung monitor features a small joystick for menu control, similarly located at the back and accessible from the right if you are sitting in front of the screen. Compared to the regular menu buttons seen in most monitors, the joystick is more intuitive and makes for faster menu navigation.


For input, the C27HG70 has two HDMI ports and one DisplayPort, all of which are down-facing at the rear. Additionally, the monitor has one audio out, one mic in, and two USB 3.0 down ports – all of them are in the same location as the video input ports. One of the USB ports also supports fast charging, which is convenient.


The stand has a different design compared to most monitor stands. It looks a lot like a monitor arm, with the joint in the middle section translating to a different height adjustment. The stand, which has cable management, has a Y-shaped base and takes up more desk space than most monitor stands. If you have a small desk or simply don’t like the stand design, you can always switch to a third-party monitor stand or arm.

Regarding ergonomics, the stand is decent. It offers full adjustment options, including tilt and swivel, but the adjustment ranges are not that great. The two Dell monitors above are much better on that front, offering a significantly better swivel range.


Although it’s clearly marketed for gaming, the C27HG70 is also a great display for productivity and watching movies – the large screen and QHD resolution are beneficial for the former while the high contrast ratio is great for the latter. The monitor has good color accuracy out of the box and boasts near-perfect coverage for the sRGB color space once fully calibrated. On the other hand, the viewing angles are inferior compared to IPS monitors.

Like our top pick, this Samsung product is a certified VESA DisplayHDR monitor, but the classification is lower. It falls under the DisplayHDR 600 classification, which is the mid-range classification in the VESA HDR standard. While it supports a wider color range and features a high contrast ratio, it can’t get as bright as the Acer Predator X27 when in HDR mode, so the overall HDR performance is only decent at best.

For gaming, the C27HG70 is an excellent monitor, especially if you love to play open-world RPGs and survival horror games. It has a fast response time – which is notable for a VA monitor – and a low input lag even when in HDR mode. This monitor also features FreeSync technology, with an effective range of 48-144 Hz when connected via DisplayPort. When the monitor is connected using an HDMI cable, the max refresh rate with FreeSync drops to 100 Hz, translating to a narrower FreeSync range.

Sadly, the monitor’s curved screen doesn’t really make for a very immersive experience when gaming, even though the curvature is on the aggressive side. This is due to the screen size and aspect ratio of the monitor. If you really want a more immersive experience when gaming, go for a curved ultrawide monitor instead.


All in all, the C27HG70 is one of the best 27-inch monitors on the market. It’s great for all-around use, offering good picture quality and great gaming performance. If you want a QHD monitor that’s more inclined toward entertainment than the Dell U2717D, get this product instead.
