The LG 27GR83Q-B is a mid-range 27-inch, 1440p gaming monitor. Part of the 2023 UltraGear gaming lineup, it's a step-down model from the LG 27GR93U-B with a lower resolution, but it has a higher 240Hz refresh rate. It has features you'd expect to find in a gaming monitor, like FreeSync VRR support and G-SYNC compatibility, and it even has HDMI 2.1 bandwidth to take full advantage of modern graphics cards. It doesn't have a ton of extra perks besides the typical gaming modes like crosshairs and a black stabilizer, but its audio port supports DTS Headphone:X audio, so you can listen to high-quality audio with compatible headphones.
Our Verdict
The LG 27GR83Q is decent for PC gaming. It has a high 240Hz refresh rate that you can achieve over DisplayPort and HDMI connections, and it supports any type of VRR format. It even has HDMI 2.1 bandwidth to take full advantage of modern graphics cards. It also has a fast response time at any refresh rate for sharp motion, and it has low input lag for a responsive feel. The one downside is that it's disappointing for dark room gaming because it has a low contrast ratio and lacks a local dimming feature to further improve the contrast.
- 240Hz refresh rate.
- Supports HDMI 2.1 bandwidth and VRR.
- Fast response time at any refresh rate.
- Low input lag.
- Low native contrast ratio.

The LG 27GR83Q-B is good for console gaming. It has HDMI 2.1 bandwidth to take full advantage of the PS5 and Xbox Series X|S, but because it has a 1440p resolution, 4k images aren't as sharp as on a 4k monitor. That said, gaming feels responsive thanks to its low input lag, and it has a fast response time across its VRR range. However, it has limited picture quality, especially for HDR gaming, as blacks look gray in the dark, and it lacks a local dimming feature.

The LG UltreaGear 27GR83Q-B is good for the office. It gets bright enough to fight glare, but it struggles to handle glare from bright sources. It also has wide viewing angles that keep the image consistent from the sides, but without swivel adjustments, it's harder to share your screen with someone else. Luckily, it has good text clarity, and its 27-inch screen is big enough to open two windows side-by-side. Unfortunately, it doesn't have many extra features like a KVM switch or USB-C port, as it's limited to two USB-A ports.

Bright enough to fight some glare.
- Wide viewing angles.
- No swivel adjustment.

Popular Monitor Comparisons
The LG 27GR83Q-B is a decent mid-range gaming monitor that has more gaming features than similarly priced displays. Its HDMI 2.1 bandwidth lets you take full advantage of current-gen gaming consoles and modern graphics cards, and its 240Hz refresh rate is also ideal for competitive gaming. It also has a fast response time and low input lag, making it a well-rounded display for gaming. It isn't as versatile for other uses like productivity as some other options like the Gigabyte M27Q X, but if you're after a low-cost, high refresh rate gaming monitor, you can't go wrong with this one.

The AOC Q27G3XMN and the LG 27GR83Q-B are both 27-inch, 1440p gaming monitors. The AOC is the better choice for most gamers, as it has much deeper blacks, highlights that pop, and more vivid colors. However, the LG has much better viewing angles, so you may prefer it if you need to share your screen with someone else, though it doesn't swivel.
The LG 27GR83Q-B is a newer monitor than the LG 27GP850-B/27GP83B-B, but it isn't a direct replacement either. This is because the 27GR83Q-B has a higher 240Hz refresh rate, and it also supports HDMI 2.1 bandwidth, which the 27GP850-B doesn't support, and this allows the 27GR83Q-B to take advantage of modern graphics cards and gaming consoles. The 27GP850-B displays more colors accurately, but other than that, the two monitors perform similarly.
The Dell G2724D and the LG 27GR83Q-B are both 1440p gaming monitors, with a few differences. The LG has a higher 240Hz refresh rate with a smoother feel, so this is something to consider if you play games at high frame rates. The LG also supports HDMI 2.1 bandwidth, which the Dell doesn't, so your graphics card doesn't need to use compression to reach high frame rates over HDMI. The Dell does have some advantages, though, as its stand can swivel, which the LG can't do.
The LG 27GR83Q-B and the MSI Optix MAG274QRF-QD are both low-cost 1440p gaming monitors, but there are some differences. The main difference is that the LG has a higher 240Hz refresh rate and better motion handling. The LG also supports HDMI 2.1 bandwidth to take full advantage of modern graphics cards and gaming consoles. While the LG is the better choice in well-lit rooms, the MSI has a few extra office-use features, like better ergonomics and a KVM switch.
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.
