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.

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.

Back
Wall Mount : VESA 100x100

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.

Borders
Borders

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.

Thickness
Thickness (with stand)
:
8.7" (22.1 cm)
Thickness (without stand)
:
2.4" (6.1 cm)

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.

7.0 Build Quality

The build quality of the Acer Predator is quite good. The parts are all plastic but do feel well constructed.

6.4

Picture Quality

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.

6.1 Contrast
Native Contrast
:

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.

4.5 Black Uniformity

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.

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.

6.0 Reflections

The monitor is a bit more reflective than most monitors. This results in brighter and more distinct reflections which may be an issue in brighter rooms.

9.2

Motion

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.

OD Extreme

The Acer Predator XB271HU has a very fast response time, which is excellent when watching fast-paced content such as playing fast paced video games or watching sports. Pixel transition speed can be modified by changing the 'OD' (Overdrive) setting. We recommend using the 'Normal' setting for fast response with minimal overshoot, but if you are bothered by the lighter trails following moving objects caused by pixel transition overshoot, you should use the 'OD Off' setting. We don't recommend using 'OD Extreme', as it introduces significant and easily visible overshoot artifacts behind moving objects.

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.

Compared to other Monitors

Left: Samsung CHG70. Middle: Acer Predator XB271HU. Right: AOC AGON AG271QX
Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Acer Predator XB271HU is a high-end monitor with very good overall performance, especially for gaming (see our recommendations for the best gaming monitors). However, it is far from perfect, especially when viewed in a dark room. While it is a good jack-of-all-trades, for specific uses there may be other monitors to consider. See our recommendations for the best monitors.

ASUS ROG Swift PG279Q

The ASUS ROG PG279Q is better than the Acer Predator XB271HU. The ASUS has slightly better motion blur, which is great for gaming and comes with marginally better out-of-the-box color accuracy that is great for office use. Also, if you plan to use it for media creation, the better black uniformity of the ASUS makes it a better choice.

Dell S2716DGR/S2716DG

The Acer Predator XB271HU is a monitor that has good viewing angles and performs better in almost all uses than the Dell S2716DG. But if you sit directly in front of the monitor and want the fastest response time for gaming, and an image with minimal blur, get the Dell. The Acer Predator XB271HU has better gray uniformity so that you browse the web without any clouding on your screen. On the other hand, the Dell S2716DG has better reflection handling.

Gigabyte Aorus AD27QD

The Gigabyte AD27QD is better than the Acer Predator XB271HU. The Gigabyte AD27QD supports HDR content and has a wide color gamut that can display rich and saturated colors. The Gigabyte AD27QD can handle reflections better and supports the FreeSync variable refresh rate technology for tear-free gaming. The Acer, on the other hand, has more uniform blacks and slightly better ergonomics. The Predator supports the G-SYNC variable refresh rate, which is great if you have a compatible NVIDIA graphics card.

ASUS ROG Swift PG279QZ

The ASUS PG279QZ is somewhat better than the Acer Predator XB271HU. The ASUS PG279QZ has marginally better reflection handling, and it ships with a slightly better pre-calibration which is important for office users that usually don't calibrate their monitors.

Samsung CHG70

The Samsung CHG70 and the Acer Predator XB271HU have similar overall performance. They have different panel types, however, so each one is better than the other in different aspects. The Samsung CHG70 supports HDR and performs decently in that mode, and it also supports local dimming that makes blacks look deep in a dark room. The Samsung CHG70 has better reflection handling and a curve profile that some people like. The Acer Predator XB271HU, on the other hand, has better ergonomics so you can easily position it to your liking. The Acer has wider viewing angles due to its IPS panel, and thus it's easier to share your work.

AOC AGON AG271QX

These are two different types of monitors, each with their advantages and disadvantages. The Acer Predator XB271HU is a G-SYNC compatible monitor that has wider viewing angles, so the image remains accurate when viewed from the side. The Acer also has better ergonomics so you can position it to your liking with ease. If however, you have a dark room and sit straight in front, the FreeSync compatible AOC AGON AG271QX has more uniform blacks and a faster response time that leaves only a small blur trail behind fast-moving content.

Dell S2719DGF

The Acer Predator XB271HU is better than the Dell S2719DGF. The Acer has better viewing angles, an optional black frame insertion feature, and better black uniformity. For gaming, it depends somewhat on your hardware, as the Acer supports G-SYNC variable refresh rate technology whereas the Dell supports FreeSync.

BenQ Zowie XL2540

The Acer Predator XB271HU is better than the BenQ Zowie XL2540. The Predator has a higher native resolution and larger screen, so you can see more fine details in games. The Predator also has wider viewing angles, which is especially important as the edges of the screen won't fade if you're sitting too close. While both support VRR, the Predator uses NVIDIA's G-SYNC technology, whereas the Zowie uses AMD's FreeSync technology.

Acer Nitro VG271

The Acer Predator XB271HU is slightly better than the Acer VG271 for most uses and is much better for gaming. The XB271HU has a much better stand, offering a full range of ergonomic adjustments, and it has better motion handling, with a slightly faster response time. The XB271HU also has a higher resolution screen, so you can see more fine details in your favorite games.

Acer Predator X27

The Acer Predator X27 is better than the Acer Predator XB271HU. The X27 has a higher native resolution, so you can see more details, and it supports HDR. It displays a wider color gamut, great for professional users in print and marketing. The XB271HU has lower native input lag, great for gamers, and has an optional black frame insertion feature that can clear up motion.

LG 27UK650-W

The LG 27UK650 is a bit better than the Acer Predator XB271HU. The LG 27UK650 is a 4k monitor that supports HDR. It supports FreeSync VRR, can get brighter than the Acer, and has better reflection handling. The Acer Predator, on the other hand, has better ergonomics and is easier to place comfortably. It has a lower input lag and supports G-SYNC VRR over a wider range of frequencies and can offer you a tear-free gaming experience.

LG 32GK850G-B

These are two different types of monitors, each with advantages and disadvantages. The Acer Predator XB271HU has wider viewing angles and is a better choice if you'll be looking at the monitor from the side, like when you're collaborating with people. The Acer also has a better ergonomic stand that allows you to place it in a comfortable position with ease. The LG 32GK850G is larger, and so you can work more comfortably, and has a better dark room performance with blacks that are more deep and uniform than on the Acer.

Dell S2417DG

The Acer Predator XB271HU is marginally better than the Dell S2417DG. The Acer has an IPS panel (vs. the TN Panel on the Dell) that provides it with better viewing angles which are important when you look at the monitor from the side such as in an office environment. The Acer has a larger screen size that allows you to work more comfortably and better enjoy multimedia content. On the other hand, the Dell can handle reflections slightly better, and this great if you place it in a room with many light sources behind you.

Samsung C49HG90/CHG90

The Acer Predator XB271HU is better than the Samsung CHG90. The Acer is equipped with an IPS panel and thus has better viewing angles, which is great for collaborative work. The Acer is also flicker free and has a faster pixel response time which leaves only a small blur trail. The Samsung CHG90, on the other hand, has a local dimming feature and better contrast ratio and black uniformity, so it performs much better in dark environments. The Samsung CHG90 also has a wide color gamut and supports HDR to enhance your viewing experience.

Samsung C34F791/CF791

If you want to work on the same monitor side-by-side with your colleagues at the office, then the Acer Predator XB271HU is a better choice than the Samsung CF791 as it has better viewing angles. The Acer is also better for gaming as it has better input lag, better image flicker to clear blur, and you can easily position it to match your liking. On the other hand, the Samsung CF791 is a larger monitor with higher resolution, giving you more area and more detail to work with.

Acer Predator XB273K

The Acer Predator XB273K is slightly better than the Acer Predator XB271HU. The XB273K has a higher resolution to display more details on your screen and supports HDR, great for HDR gaming. The XB271HU has a higher refresh rate, a BFI feature that helps improve the appearance of motion, and better ergonomics to help position it comfortably.

Amazon.com

7.7 Mixed Usage
Good monitor for a mixed usage. The Acer Predator XB271HU is a well-rounded display that is a safe choice for those looking for a screen to use with multiple types of tasks. Its wide viewing angle makes it easy to share with others, and its gaming performance is class leading. Unfortunately, though, its overall picture quality could be a bit better.
7.8 Office
Very good monitor for office use. The Acer Predator XB271HU features an excellent stand with complete articulation making it easy to find a comfortable position. It offers a good amount of screen real-estate for productivity, and its wide viewing angle and rotating feature makes it powerful in a more communal working environment.
8.5 Gaming
Remarkable gaming monitor. The Acer XB271HU's 144 Hz refresh rate, G-SYNC support, and excellent motion blur provide an exceptional gaming experience. Input lag is low, and it even sports a flicker (BFI) feature to further enhance motion clarity. Its only downside is its average picture quality, which mostly an issue for darker viewing environments.
7.4 Multimedia
Decent monitor for consuming media. The Predator's excellent handling of motion and uniform screen make it a great choice for watching high-refresh rate content such as sports, but its low contrast and lack of HDR related features means its picture quality is only about average in a dark room.
7.6 Media Creation
The Acer XB271HU is a capable monitor for creating media. Its screen is uniform, and it is easily calibrated to track the s.RGB target almost perfectly. Unfortunately, though, it does not cover wide gamuts like Adobe RGB and DCI-P3, making it a bit limited for producing print and HDR content.
5.8 HDR Gaming
HDR is not supported, which is the same as most monitors available at the moment. For an HDR monitor, see the Samsung CHG70.
