The Acer VG271U is a good 1440p IPS monitor with an excellent 144Hz refresh rate. It has decent picture handling, excellent motion handling, and outstanding low input lag, and is a great choice for a gaming monitor. This monitor supports HDR, and unlike the 1080p version, the Acer Nitro VG271, it can display a wider color gamut, although it still can't get very bright in HDR. Unfortunately, the unit we tested has terrible black uniformity, although this does vary between units, and the stand has very limited ergonomics and can only tilt.
The Acer VG271U is a good monitor for most uses. The low input lag, fast response time, and FreeSync support make it a good monitor for gaming. The 1440p resolution makes it easier to multitask, and it's great for office use or media creation. Although it supports HDR and can display a wide color gamut, it can't get very bright in HDR and can't display deep blacks in a dark room.See our Mixed Usage recommendations

Overall, this is a great monitor for gaming. It has outstanding low input lag, an excellent response time, and it supports FreeSync. The high-resolution screen is great for gaming, as you can see more fine details in your favorite games. Unfortunately, the stand has bad ergonomics, and can only tilt.See our Gaming recommendations
This is a good monitor for multimedia. The 1440p resolution is great for watching videos, and the wide viewing angles are great for sharing your favorite clips with a few friends. Unfortunately, it doesn't look great in a dark room, as it has terrible black uniformity.See our Multimedia recommendations
Good monitor for media creation. The 1440p, 27" screen is great for multitasking and makes it easier to see more of your work at once. It has wide viewing angles, which is great, but the stand has bad ergonomics, and can only tilt. This monitor has a great SDR color gamut and has excellent coverage of the Adobe RGB color space.See our Media Creation recommendations
Decent monitor for HDR gaming. It has low input lag and an excellent response time, and it supports FreeSync, which is great. It can display a wide color gamut, but it can't get very bright in HDR, and can't display deep blacks in a dark room.See our HDR Gaming recommendations
The stand is relatively small, and has an identical design to the VG271, but with a blue finish. It supports the monitor well overall but wobbles quite a bit when nudged.
Unfortunately, the stand has very limited ergonomic adjustments. It can only tilt and has no height adjustment or swivel. There is no cable management either.
The back of the monitor is very basic, with almost no design features and no RGB bias lighting. There is a quick release on the stand, and it can be VESA mounted without any spacers.
The monitor itself isn't very thick and looks great VESA mounted. The stand sticks out a bit, though, and prevents the monitor from being placed fully against the wall behind it.
Update 07/19/2019: A reader pointed out an issue that we had overlooked. There is a slight gap between the panel and the inside edge of the bezel, and this gap is slightly wider on the right side of the monitor. We don't think this is a serious issue, but it is present on our unit as well.
The Acer VG271U has decent build quality. Except for the above issue, there are no obvious issues or concerns.
Mediocre contrast ratio, but in the same ballpark as the VG271. In a bright room this isn't an issue, but in a dark room blacks appear gray. These results are fairly typical for monitors with IPS panels.
The Acer VG271U does not have a local dimming feature. The above video is provided for reference only.
Very good peak brightness in SDR. The VG271U is quite a bit dimmer than the Acer Nitro VG271. This is unexpected, but we have rechecked both, and it's a real difference between them.
Like most IPS monitors, the VG271U has very good horizontal viewing angles. The black levels remain almost constant to any angle, but the brightness drops off gradually and colors lose accuracy.
Very good vertical viewing angles. The brightness drops off a bit faster vertically than horizontally and colors shift faster, but this shouldn't be an issue for most people.
Excellent gray uniformity. There is some vignetting visible in the corners, and the sides of the screen are slightly darker. The center of the screen is very uniform, though, and there is very little dirty screen effect.
Unfortunately, the Acer VG271U has terrible black uniformity, with significant clouding and backlight bleed throughout. This varies between units, though, and depends on the manufacturer's quality control standards. If you have the VG271UP, let us know how you find the black uniformity in the discussions down below.
Update 08/16/2019: We retested the pre-calibration of this monitor with the Color Space set to 'sRGB'. With this setting, the monitor is more accurate out of the box. We've updated the results and scores, and our text below.
Out of the box, this monitor has very good accuracy. Gamma is very close to 2.2, and tracks the sRGB target curve very well. There are some inaccuracies in all colors and shades of gray that some people might notice, and the color temperature is a bit warm.
Update 08/16/2019: After remeasuring the pre-calibration results of this monitor, we've recalibrated it as well. We've updated the results and scores, as well as our ICC profile.
After calibration, the VG271U has outstanding accuracy. Colors and white balance are almost perfect, with no noticeable inaccuracies, and the color temperature is very close to our target of 6500K. Gamma follows the sRGB target curve almost perfectly.
You can download our ICC profile calibration here. This is provided for reference only and should not be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.
sRGB Picture Mode: User (calibrated)Adobe RGB Picture Mode: User
Excellent SDR color gamut, slightly better than the VG271. It can display the whole sRGB color space, which is great, and it has great coverage of the Adobe color space, which is great for professional photo editing.
sRGB Picture Mode: User Adobe RGB Picture Mode: User
Excellent SDR color volume. It can display most colors in its gamut at almost all brightness levels, but can't display dark saturated colors very well. Saturated colors are almost as bright as pure white, except for blues which, like most displays, aren't as bright as pure white.
DCI P3 Picture Mode: HDR→ HDR400Rec. 2020 Picture Mode: HDR→HDR400
Decent HDR color gamut. Unlike the VG271, this monitor can display a wide color gamut, which is great, although it's a relatively minor difference and most people won't notice it.
DCI P3 Picture Mode: HDR→ HDR400Rec. 2020 Picture Mode: HDR→HDR400
Disappointing HDR color volume, slightly worse than the VG271. Colors aren't as bright as pure white, and it can't display dark saturated colors very well.
There are no signs of temporary image retention on this monitor, which is great.
Excellent gradient performance, with very little banding. There is a noticeable hard line in the bottom blue line, this is noticeable on the monitor.
The gradient was measured with 10-bit color, which is only possible at 120Hz and not at the monitor's native 144Hz refresh rate. At 144Hz, the color depth is limited to 8-bit, and there is more noticeable banding.
Unfortunately, there are noticeable signs of color bleed on the Acer VG271U, even slightly more than the VG271. This isn't very noticeable in real content, though, and it might vary between units.
Decent reflection handling, similar to the Gigabyte Aorus AD27QD. Direct reflections aren't fully diffused across the screen, and they may be distracting in a bright room.
The VG271UP has an excellent response time, and there is very little blur behind fast-moving objects. The level of overdrive can be changed between three settings: 'Off', 'Normal', and 'Extreme'. We recommend the 'Normal' setting, as the 'Extreme' setting has severe overshoot in some transitions, especially in dark scenes. The overdrive must be set to either 'Normal' or 'Off' before enabling FreeSync. Conversely, FreeSync can't be enabled if the overdrive is set to 'Extreme'.
At 144Hz, the VG271UP is limited to an 8-bit color depth. 10-bit is only supported at 120Hz, which likely has a slightly slower response time.
The VG271UP is completely flicker-free, which is great. Like the VG271, there is an optional black frame insertion (BFI) feature known as VRB, and there are two modes, 'Normal' and 'Extreme'. The charts above were taken in the 'Extreme' mode. The 'Normal' setting is a bit brighter, as shown here, but slightly less effective at reducing blur, as you can see in this motion photo.
Note that BFI is only available if the source refresh rate is at least 120Hz, and it can't be used simultaneously with FreeSync.
The VG271U has an excellent refresh rate. It supports FreeSync, even when connected to a recent NVIDIA graphics card, although this model isn't officially supported by NVIDIA.
Note that FreeSync isn't available if the overdrive is set to 'Extreme' or if the black frame insertion feature is enabled.
Outstanding low input lag, even when connected to a 60Hz source like a game console. As 10-bit color is only supported at 120Hz, we measured the HDR input lag at 120Hz. The other input lag measurements were taken at 144Hz.
This monitor has a great 27", 1440p screen, which makes it easier to multitask than on the VG271, which has a native resolution of 1080p.
There is a headphone jack on the monitor, and the volume can be controlled from the monitor's on-screen display.
There are a few additional features on the VG271U, but it lacks many of the advanced gaming features found on more expensive models, like the Gigabyte Aorus AD27QD. There is an option to add virtual crosshairs, and it supports picture-in-picture and picture-by-picture.
The controls are located on the back, right-hand side of the monitor. The controls aren't very intuitive, unfortunately, and it can take some time getting used to navigating the menus.
We tested the 27" VG271UP, version Pbmiipx, model UM.HV1AA.P01, which is the only size available. The VG271UP is part of Acer's Nitro VG1 lineup, which has other models available. We do not expect our review to be valid for the other models.
If someone comes across a different type of panel or if their VG271UP 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.

The VG271UP we reviewed was manufactured in November 2018.
The Acer VG271UP is a great gaming monitor, but there are better options available for less. See our recommendations for the best monitors, the best 27 inch gaming monitors, and the best budget monitors.
The ASUS TUF VG27AQ is significantly better than the Acer VG271UP. The ASUS has much better ergonomics, black uniformity, as well as a faster response time. However, the Acer has better color accuracy and can get brighter in HDR content. Additionally, the Asus' refresh rate can be factory overclocked to 165Hz, providing a smoother gaming experience overall.
The LG 27GL850-B is better than the Acer VG271UP. The LG 27GL850-B has better ergonomics, so you can position it to your liking with ease, and has a faster response time that helps deliver slightly crisper motion. The Acer VG271UP has an optional Black Frame Insertion feature to make motion crisper, and although it has marginally better contrast, its terrible black uniformity is noticeable in a dark room.
The Acer VG271UP and the MSI Optix MAG271CQR use different panel technologies, each with their own strengths and weaknesses. The MAG271CQR has better contrast and better reflection handling than the VG271UP. The Acer supports HDR, has better viewing angles, and has much better gradient handling.
The Acer Nitro VG271 and the Acer Nitro VG271UP are extremely similar. The VG271UP has a higher native resolution, but unfortunately, the unit we tested has terrible black uniformity. The VG271 is significantly brighter in SDR, but there are no other significant differences between these two models.
The ASUS VG279Q is a bit better overall than the Acer VG271UP, depending on your use. The VG279Q has much better ergonomics and better black uniformity, although the black uniformity varies between units. The VG271UP, on the other hand, has a higher native resolution, and it supports HDR, so it might be better for some people, especially if you plan on VESA mounting the monitor and ergonomics don't matter to you.
The Acer Predator XB271HU is slightly better than the Acer VG271UP. The Predator supports G-SYNC VRR, is much easier to position comfortably, and its black uniformity, albeit not good, is not terrible like the Asus. The Asus, on the other hand, supports HDR, though it doesn't add much, and has a little better reflection handling to minimize distractions.
The Acer VG271UP is a bit better than the Dell S2716DGR. The VG271UP supports HDR, has much better viewing angles, and better gray uniformity. The Dell S2716DG, on the other hand, has a faster response time, a much more versatile stand, and it supports G-SYNC instead of FreeSync.
