The Acer Nitro VG271UP Pbmiipx 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 Pbmiipx, 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
The Acer Nitro VG271UP 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.
- Incredibly low input lag.
- Outstanding viewing angles.
- Terrible black uniformity.
- Bad ergonomics.
Good monitor for office use. The Acer Nitro VG271UP 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.
The Acer Nitro VG271UP 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.
Okay for multimedia. The 1440p resolution on the Acer Nitro VG271UP 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.
The Acer Nitro VG271UP 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.
Passable monitor for HDR gaming. The Acer Nitro VG271UP 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.

Popular Monitor Comparisons
The Acer Nitro VG271U is a good 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 LG 27GL850-B/27GL83A-B is better than the Acer Nitro VG271UP Pbmiipx. 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 ASUS TUF VG27AQ is significantly better than the Acer Nitro VG271UP Pbmiipx. 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 Acer Predator XB271HU Bmiprz is slightly better than the Acer Nitro VG271UP Pbmiipx. 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 Nitro VG271UP Pbmiipx is slightly better than the Dell S2417DG. The VG271UP supports HDR, has a larger screen, and has much better viewing angles. The Dell S2417DG, on the other hand, has a much better stand with excellent ergonomics, and it supports G-SYNC instead of FreeSync.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
