The Acer Predator XB271HU delivers a flawless gameplay experience thanks to G-SYNC, ULMB, fast response time, high refresh rate, and low input lag. The image quality is stunning as well though calibration is required. Versatile design and extra gaming features are a nice addition as well.

  High refresh rate, low input lag, and quick response time make for fluid gameplay, NVIDIA G-SYNC and ULMB technology, Plenty of gaming features, Great image quality after calibration, Full ergonomic support

• -

  Expensive, Requires calibration out of the box, IPS glow and mediocre contrast ratio (as expected from this panel technology)

It comes as no surprise to me that last year's Acer Predator XB271HU is still available even though the gaming monitor market is swiftly changing with HDR and 4K being all the rage nowadays.

  Truly superb gaming performance, Very good picture quality even without calibration, Refresh rate can be overclocked to 165 Hz, G-Sync module ensures smooth action, starting at 35 Hz/FPS and going all the way up to 165 Hz/FPS, Insanely thin screen edges, Great ergonomics, the screen can easily be...

  Poor-quality OSD buttons, Unintuitive OSD controls, Some slight color banding is present in deep shadows, even after calibration, Less-than-stellar backlight uniformity, The built-in speakers are a joke, Still quite expensive, Only makes sense if you own an NVIDIA graphics card, Short DisplayPort...

This is a great gaming monitor. The Acer Predator XB271HU's 144Hz refresh rate, G-SYNC support, and excellent low input lag provide a great gaming experience. Unfortunately, it delivers only average picture quality, which is mostly an issue for darker viewing environments due to the low contrast...

There sure arent a whole lot of options on the market for WQHD (2560 x 1440) 144 Hz monitors, and even less options when youre looking for an IPS display panel. Heck, you dont have a lot of options for WQHD 144 Hz TN panels, either, especially when looking for 27-inches or larger.

The Acer Predator XB271HU is one of a new breed of gaming monitors that not only features the high refresh rate you expect of a gaming display but has the great image quality you’d associate with an IPS panel too.

• +

  Superb overall image quality, G-Sync eliminates tearing and stutter, 165Hz IPS panel is fantastic for gaming, Good design and build quality

• -

  Expensive, Only two inputs, Speakers are weak

A fantastic gaming monitor that fits both gamers and professionals, but has a steep price tag that’s scares away all but those with deep pockets.

This monitor really checks all the boxes, IPS panel for better colors, high refresh rate, 2K resolution, and GSYNC! This is my first high refresh rate monitor and it really does make a difference.

I would defiantly recommend this to anyone looking for a new monitor. Im running an i7 6700K, 32GB RAM, Gigabyte 980 Ti, Samsung 960 Pro M.2 drive, RM 850i PSU.

  - Picture is amazing right out of the gate, no calibration needed at all. - Basically zero light bleed. - The viewing angles are amazing. - G-Sync works amazing.

• -

  - Honestly at this point and time, having the monitor now for 6 months or so, I cant find anything I dont like about it other then the price. But at the same time you really are getting what you pay for. - You better have a pretty decent video card to get the maximum potential out of it.

The monitor default color has a bit of a yellow tint that requires you adjust it a bit, tried what one of the other reviewers suggested and updated the temp -> Color temp/User/RGain/85/83/100 Also one annoyance is that the menu controls on it are clunky and the timeout before it goes away is too...

Amazing screen ! Size, shape , tech , material, design, all combined togather to make this perfect item and to give you the best visual gaming experience ! I guess whatever a rig specs is built on, it is nothing without a perfect visual output.

This makes games look absolutely gorgeous! I primarily play Blizzard games (WoW mostly) and it is absolutely stunning! When you combine new changes to the graphics engine Legion brought and this monitor, you get perfection!

  Beautiful Display True 165 Refresh Runs well with GTX 970 Extreme Edition & GTX 1080(This one was just a test)

I bought this monitor in early 2020. I ended up buying two monitors, they were both perfect. Image quality is awesome and for 27" they are amazing. If you want to game with them, there are a few great features for showing FPS, boosting refresh rate to 165hz, and for having a crosshair on your view,...

I would absolutely purchase this again, as this is the best looking monitor I have ever owned. 2K resolution of this monitor seems to be a sweet spot for me as I pair it with a 1080GTX max everything at 144 making gaming is super smooth (have not bothered to overclock to 165)

• +

  - Displays quality far and way the best of any monitor that I have owned (color and smooth motion) - Great viewing angles - Good solid base - Good clean design; zero bezel on three sides and not too "loud" for a "gaming" monitor

• -

  - was a little funky using display port during initial testing of my computer build (only worked with HDMI). However, this was my first computer build, so might of been something on my end and it now works fine with displayport

Everything is good in this monitor so smooth. u have to celebrations because the white near from yellow , and the only issue is the bleeding and of course because its an IPS Panel.

Be careful with the weight of the monitor and where you put it. I've had one fall forward after someone bumped my desk and had to purchase a new one. Other than that I'd say the quality is exceptional. The 165hz refresh is buttery smooth and the colors are vibrant. Contrast is fairly good also.

I chose this over its ASUS counterpart the pg279q for better quality control and a better stand. If you don't play fast shooters like cs:go and care less about refresh rate, go with the x-34 ultrawide (may very well look nicer) or a 4k display.

• +

  It was a tossup between this and the x-34 (ultrawide), and I'm glad I chose the 271! I previously owned a 1440p display, but the step up from 60hz to 165 is INSANE! As someone who loves fast-paced competitive video games (cs:go, dota 2, overwatch, bf4, and many more) I knew I needed a high refresh...

  YES, IPS PANELS HAVE SOME BLB. My last 1440 display did, and this one is no exception, but it is very minor. A small amount of light in the corners is completely normal, but only visible on a completely black screen and otherwise doesn't affect experience at all.
