The Acer Nitro VG271U is a good 1440p IPS monitor with an excellent 144Hz refresh rate. It has good motion handling, variable refresh rate (VRR) support, and incredibly low input lag, making it a good choice for gaming. This monitor supports HDR, and unlike the 1080p version, the Acer Nitro VG271, it can display a wide color gamut, although it still can't get very bright in HDR. Unfortunately, it has a mediocre contrast ratio and the unit we tested has terrible black uniformity, although this does vary between unit. However, it has wide viewing angles for when you need to share your screen with others.

Our Verdict

7.5 Mixed Usage

The Acer Nitro VG271U is a good monitor for any use. It performs best as a gaming monitor with its high refresh rate, FreeSync VRR support, good motion handling, and low input lag. Unfortunately, it's not a good choice for dark room viewing with a mediocre contrast ratio and terrible black uniformity. You can't place it how you like in an office setting due to its bad ergonomics, but it has great screen real estate and outstanding viewing angles.

Pros
  • Incredibly low input lag.
  • Outstanding viewing angles.
Cons
  • Terrible black uniformity.
  • Bad ergonomics.
7.4 Office

Good monitor for office use. The Acer Nitro VG271U has great screen real estate and outstanding viewing angles. It performs well in most office environments with decent reflection handling and good peak brightness. Unfortunately, the stand has bad ergonomics, and can only tilt. However, it has good out-of-the-box color accuracy, so you won't need to get it calibrated if you don't want to.

7.8 Gaming

The Acer Nitro VG271U is a good monitor for gaming. It has an incredibly low input lag and it supports FreeSync VRR technology to reduce tearing in games. Although its response time is a bit slower than other 144Hz monitors, resulting in some motion blur, there's a black frame insertion to improve the appearance of motion. The high resolution and good size offer a more immersive gaming experience.

7.4 Multimedia

Okay for multimedia. The 1440p resolution on the Acer Nitro VG271U is great for watching videos, and the wide viewing angles are excellent for sharing your favorite clips with a few friends. Unfortunately, it doesn't perform well in a dark room, as it has terrible black uniformity and a mediocre contrast ratio.

7.4 Media Creation

The Acer Nitro VG271U is a good monitor for media creation. The 1440p, 27 inch 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 an excellent SDR color gamut and has fantastic coverage of the Adobe RGB color space used in photo editing.

6.5 HDR Gaming

Passable monitor for HDR gaming. The Acer Nitro VG271U has a low input lag and a good response time, and it supports FreeSync, which is great. Unfortunately, although it can display a wide color gamut, it can't get very bright in HDR, and it fails to bring out some highlights. It also can't produce deep blacks with a mediocre contrast ratio and terrible black uniformity.

The design on the Nitro VG271U is very simple. The whole monitor is black, except for some blue on the stand. The back of it has a premium feel, and it looks good in an office or gaming environment.

The back has a sleek design to it. The top half is plastic made to resemble metal, which gives it a premium feel. There's a quick-release button and it can be VESA-mounted. Unfortunately, there's no cable management.

The monitor itself isn't very thick and looks good if VESA mounted. The stand sticks out a bit, though, and prevents the monitor from being placed fully against a wall.

Build Quality

Update 07/19/2019: A reader pointed out an issue that we had overlooked. There's 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 Nitro VG271U has decent build quality. Except for the above issue, there are no obvious issues or concerns.

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 Nitro 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 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.
