Acer Predator XB271HK


It may be pricey, but the Acer Predator XB271HK is a 27-inch Ultra-High-Definition (UHD) gaming monitor that comes up big in terms of performance, features, and style.

Superb gaming, color, and gray-scale performance. Highly detailed UHD image quality. Attractive bezel-free design. Supports G-Sync anti-tearing and smoothing technology.

Expensive. Underpowered speakers. Two video inputs.

Conclusion You'll pay big bucks for the Acer Predator XB271HK, but its price is still in line with other IPS-based, 27-inch UHD monitors, such as the ViewSonic VP2780-4K and the NEC MultiSync EA275UHD, neither of which support Nvidia's G-Sync...

Acer Predator XB1 XB321HK 4k UHD 32 inch IPS G-Sync Gaming Monitor Review (27 inch – XB271HK)


It may not be exactly cheap as far as gaming monitors go, but the Acer XB321HK is one massive piece of 4K PC display technology which has been built with gaming in mind almost across the board in all of its core specs. Featuring a mostly simple and...

Superb color rendering ; Great design ; Includes G-Sync ; Very bright panel ; Connectivity essentials all present ; Great display space at 32 inches

No swivel adjustment ; Could use more HDI or DP 1.2 ports ; Contrast is a bit weak ; expensive enough to justify simply buying a 4K TV

Despite its minor flaws, the Acer Predator XB321HK is one excellent and well-designed 4K gamer's monitor that almost anyone will be pleased with. We particularly like its massive display space and the inclusion of G-Sync. However, this 4K PC monitor is...

Great desktop image quality.

Displays with 4K refresh rates above 60Hz may be on their way this year.

Acer Predator XB271HK 27" 4K Monitor Review


What a great time it is to be looking for a gaming monitor. With high refresh rates, G-SYNC, FreeSync, 4K, curved panels and so many more technologies

Going into this review, we had some unreasonably high expectations. Previous Acer Predator gaming monitors which graced our lab never let

I Like It!


I've owned mine for 6 weeks now. I mainly play BF4, and push it with a single GTX 980i MSI Gaming card. I'm getting about 45 FPS at 4K, looks amazing! I have not had any of the bleed issues discussed in other reviews. G-Sync works great, FPS counter is...

The only thing that is a little disappointing is the sound quality from the speakers that are built in to the monitor. Not very good at all, but I didn't buy for the sound quality. I have separate PC speakers for that.

Could have been amazing...hugely dissapointed


Maybe find another Gsynch monitor. The price point seemed okay for what I was getting but now all I have is a $900 monitor that only works half the time. I WANT to love this monitor. I WANT it on my desk. But most of all, I want one that works.

-Big -Vibrant colors -GSycn -Plenty of inputs

- Stopped working after 66 days - Screen flicker on 1/2 of the screen - Disappointing experience with ACER Customer Service (My only monitor, and I can't ship it off and continue to work...obviously) Wish they would have worked harder to resolve my...

Bad backlight bleeed


For what I paid for I would expect someone to turn on the monitor and actually check it see if it looks like dog $#!% I thought w.e new egg will rma for free and i will get the rog pg27aq... did not work out well.. one of new eggs untrained rma staff...

Good colors, nice looking, good solid feel

Quality control is trash. Backlight bleed on bottom left bad. Some on the top

Good monitor


I recommend this monitor for those who can drive it properly. I have X99 and GTX 980 Ti SLi on Win 10 Pro 64-bit. Although I would have no problem using this for other than gaming, others might disagree with the 27" screen size. It's small but it has a...

Excellent color and input lag. G-sync on this model is outstanding. Feels a little better than other g-sync models I've had. Set-up is a breeze, has lots of options for overdrive, game mode with FPS counter built-in. No dead or stuck pixels

price? I guess the X34s are going for 1100-1300, so this is cheaper. I have a feeling these can come down $100 easy so you might want to wait for a sale. I like the 4K resolution though so it's really up to what you want or need. It's zero frame isn't...

Outstanding monitor! as long as its not defective!


- Probably will end up RMA-ing the second monitor as well, and wait out for the Asus PGxxx 4K with identical specs. - Neweggs customer service best in the business!

- No other monitors on the market with the same specs (G-sync, IPS, 4k, low input lag etc.) - Looks awesome in person! - Great when it works! - The clarity of images and text is really something else on a 4K display, once you use it you won't want to...

- First monitor was defective had numerous horizontal faint lines running across the screen. RMA'd it. - Second monitor has occasional flicker, Back light bleed like the sun rising from one of the corners. - Anti Glare coating is a little too...
