The LG 27GR93U-B is a mid-range gaming monitor. It's one of two 4k, 144Hz monitors in LG's 2023 lineup, with a smaller screen than the LG 32GR93U-B. It's also a lower-end model than the older LG 27GP950-B, which has a higher refresh rate. It has features you'd expect to find in a gaming monitor, like FreeSync variable refresh rate (VRR) support and G-SYNC compatibility. It also supports HDMI 2.1 bandwidth, allowing you to take full advantage of gaming consoles and modern graphics cards. Other than that, it's rather barebones in terms of features, but its audio port supports DTS Headphone:X audio, so you can listen to high-quality audio with compatible headphones.
Our Verdict
The LG 27GR93U-B is decent for PC gaming. Some competitive gamers may find its 144Hz refresh rate limiting, but it supports HDMI 2.1 bandwidth and all common VRR formats to reduce screen tearing. Luckily, it has low input lag for a responsive feel and it has a fast response time for sharp motion at high refresh rates, but there's more blur at 60Hz. Unfortunately, it has a low contrast ratio that makes blacks look gray, so it isn't ideal for dark room gaming as it has limited picture quality.
- 144Hz refresh rate and VRR support.
- Fast response time at high refresh rates.
- Low input lag.
- Blacks look gray in the dark.
- Limited HDR brightness.
- More motion blur at 60Hz.
The LG 27GR93U-B is great for console gaming. It takes full advantage of the Xbox Series X|S and PS5 thanks to its HDMI 2.1 bandwidth, and it delivers detailed images thanks to its HDMI 2.1 bandwidth. Gaming feels responsive due to its low input lag, and it has a fast response time at 120Hz for sharp motion, but there's more blur at 60Hz. Sadly, it's a disappointing choice if you want realistic images, as it has limited picture quality due to its low contrast and lack of local dimming.

The LG 27GR93U-B is impressive for office use. It has a 4k resolution that results in high pixel density on its 27-inch screen, so it has fantastic text clarity because of this. You won't have many issues using it in a well-lit room either, as it gets very bright, but has mediocre reflection handling. It even has wide viewing angles that help when you need to share your screen with someone else, but it lacks swivel adjustment to easily turn the screen. Unfortunately, it lacks many extra productivity features, as it only has two USB ports.
- 4k resolution for sharp text and images.
- Bright enough to fight glare.
- Wide viewing angles.
- No swivel adjustment.
- Only has two USB-A ports.

The LG 27GR93U-B is good for media creation. It has impressive accuracy before calibration in its sRGB mode, and it also displays a wide range of colors. It has a high 4k resolution that helps deliver sharp images, and it performs well in bright rooms thanks to its high peak brightness. It has wide viewing angles that are useful if you often need to share your screen with a coworker or client, but it doesn't have a swivel adjustment to easily turn the screen.

- Bright enough to fight glare.
- Limited HDR brightness.
The LG 27GR93U-B has a good overall response time. It performs best close to its max refresh rate as fast-moving objects look sharp, but there's more blur at lower refresh rates.
- Fast response time at high refresh rates.
- More motion blur at 60Hz.
The LG 27GR93U-B is terrible for HDR. It has a low contrast ratio that makes blacks look gray, and it lacks a local dimming feature to further improve the picture quality. It also struggles to make colors look vivid and highlights pop.

Popular Monitor Comparisons
The LG 27GR93U-B is a good all-around 4k monitor that offers HDMI 2.1 bandwidth, VRR support, and a 144Hz refresh rate, so it's great for console gaming, but it isn't as ideal for competitive PC gaming. It also has limited picture quality due to its low contrast and lack of local dimming. While it has slightly worse motion handling than the larger LG 32GR93U-B, it's a good alternative if you want something cheaper and smaller. That said, it isn't as versatile as the Gigabyte M27U for other uses like work, so that monitor is the better choice if you want something for better value that costs less and has extra features.
See our recommendations for the best 4k gaming monitors, the best 4k 144Hz monitors, and the best 32-inch monitors.
The LG 27GR93U-B and the Gigabyte M27U are both 4k gaming monitors. They have many similar features, especially for gaming, but the LG supports higher HDMI bandwidth, so it doesn't need to use compression for demanding signals like on the Gigabyte. That said, the Gigabyte has a few extra features for productivity, like a USB-C port and KVM switch, making it the better choice for multitasking with different devices.
The LG 32GR93U-B and the LG 27GR93U-B are similar mid-range monitors, with one of the main differences being their sizes. There are still some differences in performance, though, as the 32-inch model has better motion handling, and it also has better HDR color volume for more vivid colors. Another difference is that the 27-inch model has improved brightness.
The LG 27GR93U-B and the MSI MAG 274UPF are 27-inch 4k gaming monitors. Both monitors have very similar performance; you may prefer to get whichever is cheaper. The MSI is a better choice if you want USB-C connectivity and a KVM switch. However, if you do a lot of co-op gaming, you may prefer the LG, as it has wider viewing angles.
The LG 27GP950-B is a higher-end monitor than the LG 27GR93U-B, so it has a few extra features, but they perform similarly otherwise. They each have a native 144Hz refresh rate, but the 27GP950-B has an overclock feature to go up to 160Hz. That said, the motion handling is similar between each. The 27GP950-B also has a local dimming feature, which the 27GR93U-B doesn't have, and it allows it to get brighter in HDR, but the local dimming feature is terrible overall. On the other hand, the 27GR93U-B gets brighter, making it the better choice for use in well-lit rooms.
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.
