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 Nitro VG271UP has a decent design and looks almost identical to the Acer Nitro VG271, but with a blue stand. The stand supports the monitor well but wobbles a fair bit when nudged. This monitor is decently built, but is almost entirely made of plastic. Unfortunately, the stand has very limited ergonomic adjustments, so a VESA stand might be a good idea.
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 Acer Nitro VG271U delivers decent overall picture quality. Like most IPS monitors, it can't produce deep blacks in a dark room, but it has very good viewing angles. It has good peak brightness in SDR and decent peak brightness in HDR, but small highlights in some scenes aren't as bright as they should be. Unlike the 1080p version of this monitor, the Acer Nitro VG271, this monitor can display a wider color gamut, which is great. Unfortunately, the unit we tested had terrible black uniformity, worse even than the VG271.
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.
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.
Out of the box, this monitor has decent accuracy. Gamma is relatively flat and tracks close to 2.2, and it doesn't follow the sRGB target curve. There are some inaccuracies in all colors and shades of gray that some people might notice, and the color temperature is a bit warm.
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.

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.
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 Acer Nitro VG271U has great motion handling, nearly identical to the VG271. It has an excellent response time, flicker-free backlight, and an optional black frame insertion feature. It has an excellent refresh rate, and it supports FreeSync variable refresh rate technology even when connected to a recent NVIDIA graphics card, but there is no factory overclock.
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.
The Acer VG271U has excellent low input lag, even when connected to a 60Hz source, like a game console. The 27", 1440p screen is great for multitasking and delivers a sharper image than the 1080p version of this monitor, the VG271. This monitor has a good selection of inputs, and you shouldn't have any issues connecting your devices.
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.
The Acer Nitro VG271UP is a basic gaming monitor with few additional features. It supports HDR10, picture-in-picture, and picture-by-picture, and it can add crosshairs to any game. Unfortunately, it can be difficult to navigate the OSD, as the controls aren't very intuitive.
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.
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.
