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.

Stand

:
13.2" (33.5 cm)

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.

3.3 Ergonomics
Height Adjustment
:
N/A
Switch portrait/landscape : No

Tilt Range : -20° to 7.5

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.

Back
Wall Mount : VESA 100x100

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.

Borders
Borders

The borders are very thin on three sides and don't stick out.

Thickness
Thickness (with stand)

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.

6.5 Build Quality

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.

7.1

Picture Quality

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.

6.4 Contrast
Native Contrast
:
1244 : 1
Contrast with local dimming
:

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.

Decent peak brightness in HDR, about the same as the Nitro VG271 and slightly brighter than the Gigabyte Aorus AD27QD.

For HDR to work, you have to choose the 'HDR' Picture Mode and set the HDR setting to either 'Auto' or 'HDR400'. For the purposes of our testing, we chose the 'HDR400' setting.

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.

9.8 Gradient
Color Depth
:
10 Bit

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.

7.5 Color Bleed

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.

7.0 Reflections

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.

9.1

Motion

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.

Response Time Off
Response Time Normal
Response Time Extreme

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.

Inputs

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.
