The Acer Predator XB271HU is a very good high-end IPS-type gaming monitor. It features G-SYNC and a high 144 Hz refresh rate, making it exceptionally fluid and responsive. It has a decently wide viewing angle which helps keep it versatile and it also gets bright enough to fit most environments. Unfortunately, though, its overall picture quality leaves a lot to be desired due to its low contrast ratio and cloudy blacks.
The Acer Predator XB271HU is a good looking monitor with a fairly small and sleek stand. The red accents are striking, including the Predator logo on the front. There is a range of ergonomic adjustment options to fit any desk and some basic cable management down the back of the stand. The stand also feels stable and provides good support, which is great. The borders are quite thin, which is useful for multiple-monitor setups and the build quality is decent.
The stand of the Acer XB271HU is quite small and looks good with some red accents. It supports the monitor well and feels stable, despite the small footprint.
There is quite a good range of ergonomic adjustment options available, which makes it easy to find a comfortable setup. The screen also rotates both directions to portrait, which is useful for those who would like the inputs/controls on one side or the other.
The rear of the monitor is quite basic but looks good. There is a hole in the back of the stand for cable management, as visible here. This is useful for keeping a tidy desk, free of cable clutter.
The borders of the Acer XB271HU are quite thin. This not only looks good, but is more practical for small gaps in multiple-monitor setups.
The monitor appears a bit thick when viewed from the side, as the area where the components and inputs are located is quite bulky. It can still sit quite close to a wall, but does end up taking more desk space than some other designs such as the Dell S2716DG.
The picture quality of the Acer Predator XB271HU is decent. The native contrast ratio is low, so blacks appear gray in a dark room but in a bright room, this isn't an issue. The peak brightness is good and allows the monitor to overcome glare, which is necessary because the reflection handling of this monitor is below average. Out of the box, the colors aren't very accurate, so a calibration is recommended for editing media.
The image remains accurate when viewed at an angle which is great, especially for sharing images with co-workers in an office. The monitor doesn't support more advanced features such as local dimming or HDR to improve the picture quality further, but this is true for most monitors on the market at the moment.
The Acer XB271HU monitor has an average native contrast ratio, but it is in line with other IPS monitors. When viewed in a dark room, blacks are not deep and look more like gray than really black. If ambient light is present, the low contrast ratio effect is less noticeable though.
The Acer Predator XB271HU does not have a local dimming feature. The video is for reference only.
The Acer Predator XB271HU is capable of reaching good levels of brightness, making it suitable for most viewing environments. Its constant brightness means the screen won't fluctuate in luminance depending on what's shown.
HDR is not supported.
Decent horizontal viewing angle. The monitor's reasonably wide viewing angle means no deterioration is visible when directly in front, and the screen remains usable to users sharing the screen on either side.
Great vertical viewing angle. Moving your head up and down causes no visible shift in the image, and the Acer Predator XB271 remains usable when standing above it or while sitting below the screen.
The Acer Predator XB271HU has a great overall gray uniformity, which is beneficial for scenes with large uniform areas such as browsing the web, watching sports or playing games. The 50% gray uniformity looks great, with only small imperfections, like little vertical ripples and slightly darker sides. Overall, dirty screen effect is not noticeable.
The monitor has a poor black uniformity. As seen on our test picture, some clouding and flashlighting are visible near almost every edge of the display, which hurts the black uniformity considerably. This results in blotchy dark scenes, especially when viewed in a dark room.
Out of the box and when set on the most accurate picture mode, the monitor still has poor accuracy. The white balance dE and color dE are both well over what most enthusiasts would consider inaccurate. This is particularly noticeable while looking at the pre-color picture, where the white point is completely off target.
After calibration, which was done on the 'User' picture mode, the Acer Predator XB271HU is much more precise. The white balance and color accuracy are spot on and most of the issues are corrected, especially the white point, which now is right on target. Also, after calibration, the gamma is not tracking our 2.4 sRGB target.
You can download our ICC profile calibration here.
The Acer XB271HU has no issue covering the standard s.RGB colorspace, which is great for most uses. Its coverage of the Adobe RGB colorspace, however, is quite limited, making this monitor less useful for professional use.
Good native color volume. The monitor has no issue filling up most of its native s.RGB colorspace. It does, however, have some difficulty reproducing very dark tones, mostly due to its limited contrast ratio.
HDR gamuts are not supported.
HDR color volumes are not supported.
The Acer Predator XB271HU does not suffer from image retention, as even right after the 10 minutes burn-in scene, the screen is free of any image retention.
Great performance for the Acer Predator on our gradient test. Beside the 8-bit banding, there is some little shade imperfection in the grayscale, but most of the rest of the gradient look good.
Some vertical color bleed is present, however, this won't be noticeable in most situations. It is visible in the vertical photo as different shades of gray above and below each color.
The motion handling of the Acer Predator XB271HU is excellent. It has a remarkable response time, which results in very short trails following moving objects. It uses DC dimming, so the screen is flicker-free, and BFI can be enabled to clear up motion further. The monitor has a high native refresh rate of 144Hz, which can be overclocked to 165Hz. It can use NVIDIA's G-Sync technology to display variable frame rates lower than its native refresh rate when used with a compatible video card.
Like most monitors, the XB271HU doesn't flicker and shows each image for a full frame. Without flicker, motion appears smoother, but persistence blur is more visible (as even moving images are static for the full duration of each frame). However, it is possible to use Black Frame Insertion (BFI) to add flicker and help reduce persistence blur, but only with 120Hz, 100Hz and 85 Hz inputs. This is useful for first person shooters or other fast-paced games.
The monitor has a high native refresh rate of 144Hz, which can be overclocked up to 165Hz. This results in very smooth motion and a responsive feel. NVIDIA's G-Sync on this monitor can adjust the screen's refresh rate to match the frame rate of a compatible graphics card, which allows playing graphically-intensive games with significant framerate drops without tearing or stuttering. This is one of the best 144 hz monitors we've tested in 2018.
The Acer Predator XB271HU has excellent low input lag, a high QHD resolution, and a large 27" screen, which are great for almost all usages.
Lowest input lag possible at the center of the screen, when the monitor is displaying an alternative resolution at its native refresh rate. The non-native resolution tested depends on the native resolution of the monitor, following this pattern unless otherwise specified in the Input Lag text:
|Native Resolution||Non-Native Resolution Tested|
Excellent low input lag, mostly due to the fast scan time of 144 Hz. The 60 Hz input lag is much higher, as is the input lag with ULMB (BFI) enabled at 120 Hz, but both are still fairly low. The G-sync input lag is only slightly higher than the native input lag, which is great.
The Acer XB271HU has a high QHD resolution and a large 27" diagonal, giving it lots of screen space while still having good pixel density and detail.
The on-screen display of the Acer Predator XB271HU is fairly easy to use and allows adjusting many aspects of the monitor's performance such as picture mode, calibration, response time overshoot and the power LED.
It is possible to add a central crosshair to the Predator through the on screen menu, with the 'Aim Point' option.
We tested the Acer Predator XB271HU bmiprz, which is 1440p IPS gaming monitor. There are many other variants of the Predator lineup which all support G-Sync but with different sizes, panel types, resolutions and refresh rates - a selection of which are listed in the table below.
If someone comes across a different type of panel or if their monitor doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.
