The LG 27GR95UM-B is a 27-inch, 4k gaming monitor. It's the first UltraGear gaming monitor to have Mini LED backlighting, as it has 1,560 dimming zones, and it competes with other Mini LED monitors, like the Acer Nitro XV275K P3biipruzx and the INNOCN 27M2V. It has a native 144Hz refresh rate that you can overclock to 160Hz, and it has HDMI 2.1 bandwidth to take advantage of modern graphics cards and consoles. It also has FreeSync Premium Pro and G-SYNC compatibility to reduce screen tearing. Besides that, it has typical gaming features, like Black Stabilizer and Crosshair, to help with your gaming experience, and it supports DTS Headphone:X.
Our Verdict
The LG 27GR95UM is good for PC gaming. Gaming feels responsive thanks to its low input lag and 160Hz refresh rate, and it has a good enough response time to result in minimal motion blur. It also has HDMI 2.1 bandwidth to take advantage of modern graphics cards. However, it has limited picture quality as its local dimming feature is bad, and blacks look gray in dark scenes. That said, it gets bright enough to fight glare if you want to game in a bright room.

The LG 27GR95UM is impressive for console gaming. It has HDMI 2.1 bandwidth to make full use of the PS5 and Xbox Series X|S, and its 4k resolution delivers detailed images. Plus, it has low input lag for a responsive feel, and there's minimal motion blur at most refresh rates. While it's a good choice for gaming in well-lit rooms because of how bright it gets, it's worse in dark rooms. It has a bad local dimming that fails to improve the picture quality in dark scenes and causes blooming and black crush.

The LG 27GR95UM is great for office use. Its 4k resolution results in sharp text, and it has wide enough viewing angles that keep the image consistent when viewing from the sides, like if you need to share your screen with a coworker. However, it lacks swivel adjustment, so it's hard to turn it. On the plus side, it gets bright enough to fight glare in most well-lit rooms, but its reflection handling is poor, so having a bright light shining on the screen is distracting.

Popular Monitor Comparisons
The LG 27GR95UM is a premium 4k gaming monitor with an overclockable 160Hz refresh rate and HDMI 2.1 bandwidth. It's the first LG monitor with Mini LED backlighting, and it has 1,560 dimming zones. That said, its local dimming feature performs badly, as it makes the picture quality worse with noticeable blooming and black crush. There are other Mini LED monitors with better local dimming features, like the Acer Nitro XV275K P3biipruzx and the INNOCN 27M2V. On top of that, the LG tends to be expensive, so it may be worth considering an OLED with much better picture quality if your budget allows for it.

The LG 27GP950-B and the LG 27GR95UM-B are both 4k gaming monitors in the LG UltraGear lineup, but there are a few differences. The 27GR95UM-B uses Mini LED backlighting, and even though its local dimming feature is better than on the 27GP950-B, it performs badly. One advantage of the 27GR95UM-B is that it gets much brighter, ideal for using it in a well-lit room.
The LG 27GR95UM-B and the INNOCN 27M2V are 4k gaming monitors with Mini LED backlighting and similar features. However, there are a few differences in performance, as the INNOCN has a better local dimming feature, more accurate colors, and better motion handling. However, the LG has a lower input lag at 60Hz, making it the better choice for gaming at that refresh rate.
The LG 27GR95UM-B and the LG 27G850A-B are both 4k gaming monitors, with a few differences. The 27G850A-B has the advantage if you want something for PC gaming at high frame rates, as it has a higher native refresh rate than the 27GR95UM-B, and it has a Dual-Mode feature that switches it to a 1080p resolution and 480Hz refresh rate. The 27G850A-B also has DisplayPort 2.1 bandwidth to take advantage of modern graphics cards. On the other hand, the 27GR95UM-B is the better choice if you care about good picture quality, as it's a Mini LED monitor with deeper blacks and brighter highlights. However, it's not a perfect solution as its local dimming feature causes haloing around bright objects.
The Cooler Master Tempest GP27U and the LG 27GR95UM-B are both 4k gaming monitors with similar specs. They each have Mini LED backlighting, and even though the Cooler Master has fewer dimming zones, its local dimming feature is better with less blooming and black crush. On top of that, the Cooler Master is better for productivity thanks to its KVM switch and USB-C port.
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.
