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 variable refresh rate (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:X audio, so you can listen to high-quality audio with compatible headphones.

Our Verdict

7.9 Mixed Usage

The LG 27GR83Q-B is good for most uses. It's excellent as a gaming monitor as it's packed with features like HDMI 2.1 bandwidth and VRR support, and it also has a fast response time and low input lag for a responsive feel. It's good for general work use or content creation thanks to its good text clarity, and it also gets bright enough to fight glare if you work in a well-lit room, but it has limited ergonomics as it doesn't offer swivel adjustment. It's decent for media consumption in bright environments, and it also has good image accuracy, but it struggles in dark environments, like if you're watching HDR movies, as it has a low contrast ratio.

Pros
  • Good text and image clarity.
  • Bright enough to fight glare.
  • Wide viewing angles.
  • Supports HDMI 2.1 and VRR.
Cons
  • No swivel adjustment.
  • Lacks extra office features.
  • Low native contrast ratio.
7.8 Office

The LG 27GR83Q is good for the office. It gets bright enough to fight glare, and its reflection handling is good enough if your office space has a few lights. 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.

Pros
  • Good text and image clarity.
  • Bright enough to fight glare.
  • Wide viewing angles.
Cons
  • No swivel adjustment.
  • Lacks extra office features.
8.8 Gaming

The LG 27GR83Q is excellent for 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 and gaming consoles, and it can downscale 4k signals, too. It also has a fast response time at any refresh rate for smooth 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.

Pros
  • 240Hz refresh rate.
  • Supports HDMI 2.1 and VRR.
  • Fast response time at any refresh rate.
  • Low input lag.
Cons
  • Low native contrast ratio.
7.4 Media Consumption

The LG 27GR83Q is decent for media consumption. It's good if you want to use it in a bright room as it has good reflection handling and gets bright enough to fight glare. It also delivers life-like images thanks to its good color accuracy, and the image remains consistent from the sides thanks to its wide viewing angles. However, without any swivel adjustment, placing the screen in an ideal viewing position is hard. Unfortunately, it has a low contrast ratio and lacks a local dimming feature, so it's disappointing in dark rooms.

Pros
  • Good text and image clarity.
  • Bright enough to fight glare.
  • Wide viewing angles.
Cons
  • No swivel adjustment.
  • Low native contrast ratio.
  • Lacks a local dimming feature.
7.8 Media Creation

The LG 27GR83Q is good for media creation. It has good accuracy before calibration in its sRGB mode, but you still need to calibrate it for the most accurate colors. It also has good image and text clarity thanks to its 1440p resolution, and its 27-inch screen is big enough for multitasking, but you won't see your entire video timeline at once. It has wide viewing angles that make the image consistent from the sides but lacks swivel adjustment to easily turn the screen to show someone else.

Pros
  • Bright enough to fight glare.
  • Wide viewing angles.
  • Good color accuracy.
Cons
  • No swivel adjustment.
  • Lacks extra office features.
6.4 HDR

The LG 27GR83Q is mediocre for HDR as it has limitations. While it displays a wide range of colors, not all colors are accurate due to tone mapping issues. It also has limited HDR peak brightness and color volume, so highlights don't pop, and colors aren't vivid. Unfortunately, blacks look gray in the dark due to the monitor's low contrast, and it lacks a local dimming feature to further improve it.

Pros
  • Displays wide range of colors.
Cons
  • Low native contrast ratio.
  • Lacks a local dimming feature.
  • Low HDR brightness.

Differences Between Sizes And Variants

We tested the 27-inch LG 27GR83Q-B, which is the only size available for this monitor.

Model Size Panel Type Resolution Max Refresh Rate
27GR83Q-B 27" IPS 1440p 240Hz

Our unit was manufactured in June 2023 with a BOE panel; you can see the label here.

Compared To Other Monitors

The LG 27GR83Q-B is an excellent lower 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 gaming monitor, you can't go wrong with this one.

See our recommendations for the best budget gaming monitors, the best 240Hz monitors, and the best 1440p gaming monitors.

LG 27GP850-B/27GP83B-B

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.

Gigabyte M27Q X

The Gigabyte M27Q X and the LG 27GR83Q-B are both 1440p, 240Hz gaming monitors. There are a few differences, though, as the LG supports higher HDMI 2.1 bandwidth, which is ideal for consoles or modern graphics cards, and has slightly better motion handling. On the other hand, the Gigabyte is better for content creators as it has much better color accuracy and extra perks like a USB-C port and KVM switch.

MSI Optix MAG274QRF-QD

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.

HP OMEN 27qs

The HP OMEN 27qs and the LG 27GR83Q-B are competing 240Hz, 1440p gaming monitors. They perform very similarly, and their differences come down to features. The LG has HDMI 2.1 bandwidth, letting you reach higher refresh rates over HDMI and take advantage of gaming consoles. On the other hand, the HP has a local dimming feature that helps it get brighter in HDR, but it also causes blooming, so it isn't that much of an advantage. The HP also has much better color accuracy, which is ideal for content creators.

Samsung Odyssey G7 C32G75T

The Samsung Odyssey G7 C32G75T and the LG 27GR83Q-B are both 1440p, 240Hz gaming monitors, but they have a few differences, mainly with their panels. The Samsung has a curved VA panel with a higher contrast for deeper blacks and a local dimming feature, which the LG doesn't have. On the other hand, the LG has an IPS panel with wider viewing angles, making it the better choice for co-op gaming. They also have a few differences in gaming performance, as the LG has HDMI 2.1 bandwidth and a faster response time for smooth motion. The LG has fewer bugs, as the Samsung has some flicker with VRR enabled.

Gigabyte M27Q (rev. 1.0)

The LG 27GR83Q-B and the Gigabyte M27Q (rev. 1.0) are both budget-friendly gaming monitors, with a few differences. The LG is a bit higher-end as it has a faster 240Hz refresh rate and supports HDMI 2.1 bandwidth, which the Gigabyte doesn't support. This means that the LG is the better choice for consoles or if you have a modern graphics card. The LG also has better motion handling at high refresh rates and better text clarity. If you want something for work, the Gigabyte has extra features, like a KVM switch and USB-C port.

LG 27GR83Q-B has a gamer-oriented aesthetic with a dark gray body and some branding elements on the back. Unfortunately, there's a silver reflective strip underneath the bottom bezel, which can be distracting if you have a bright light source in your room.

The build quality is good. It's mainly made of good-quality plastic, and there aren't any obvious issues. The monitor wobbles a bit on the stand, but it stabilizes quickly. The bottom bezel isn't perfectly flush with the entire screen either, but that isn't an issue unless you're really looking for it.

The SDR brightness is impressive. It easily gets bright enough to fight glare and maintains its brightness consistently across different content. That said, its minimum brightness is a bit high, which is disappointing if you want to use it in a dark room and are sensitive to bright lights. These results are from after calibration in the 'Gamer 1' Game Mode with the Brightness at its max.

The LG 27GR83Q-B has decent HDR brightness. While it gets bright, small highlights don't pop against the rest of the image because it lacks a local dimming feature. It struggles with EOTF tracking as dark scenes are overbrightened, and it has an early roll-off, so highlights don't get the brightest they could. These results are in the 'Gamer 1' Game Mode with the Brightness at its max.

The LG 27GR83Q-B has good accuracy before calibration in the sRGB mode. It isn't perfect, though, as there are inaccuracies in the white balance and colors, and even gamma is off. Luckily, the color temperature is good, as it's only slightly on the cold side, but not enough to be noticeable. Unfortunately, the 'sRGB' Game Mode locks many settings, including Response Time, so if you want to use any of those settings, you'd have to use another picture mode that has more oversaturated colors, as you can see here.

The response time at 120Hz is excellent. Unlike at the max refresh rate, the recommended Response Time setting is 'Normal' because 'Fast' and 'Faster' have too much overshoot. This means you may have to change the setting if the frame rate of your game drops or if you change games.

The LG 27GR83Q-B works well with macOS. You can reach its full refresh rate with VRR and HDR on any type of connection. With a USB-C to DisplayPort cable, there's a bug with VRR where a gray bar appears on top, which causes VRR to stop working. You need to exit the full-screen mode and go back in for it to work properly again. If you're using a MacBook, windows return to their original position when you put it to sleep and wake it up again, but not when you close the lid.

This monitor has a few extra features, including:

  • Black Stabilizer: Adjusts the gamma so that it's easier to see opponents in dark areas.
  • Crosshair: Adds a virtual crosshair that your game's anti-cheat tool won't detect, giving you a competitive advantage.
  • DFC: Changes the contrast based on the content.
  • DTS:X Headphones: The monitor offers a few different sound modes to use with DTS:X compatible devices.
  • Variable Backlight: Boosts the contrast level in HDR, but it isn't a local dimming setting.
