The LG 32GX870B-B is a high-end 32-inch, 4k OLED gaming monitor. It has a native 240Hz refresh rate that you can boost to 480Hz with a lower 1080p resolution using its Dual-Mode feature. Competing with other dual-mode options, like the ASUS ROG Strix OLED XG32UCWMG, it's an updated version of the LG 32GS95UE-B, featuring a newer fourth-gen Tandem WOLED panel for improved color purity and brightness, as it's certified for VESA DisplayHDR True Black 500. It also has high-bandwidth HDMI and DisplayPort 2.1 inputs to take advantage of the latest gaming consoles and graphics cards. It has typical gaming perks besides that, like FreeSync Premium Pro and G-SYNC Compatibility to reduce screen tearing. It has a few extra perks to help with productivity, too, including a small USB hub with a USB-C port that supports DisplayPort Alt Mode and 90W of power delivery for charging laptops.
Our Verdict
The LG 32GX870B is incredible for PC gaming. You can switch between its 4k @ 240Hz and 1080p @ 480Hz modes, so it's versatile for playing different types of games with a smooth feel. Motion looks sharp at any refresh rate, and it has low input lag that's ideal for playing reaction-based games. It supports all common VRR formats to reduce screen tearing, but there's noticeable VRR flicker with fluctuating frame rates in dark scenes. On the plus side, this monitor delivers fantastic picture quality with deep blacks in any room and highlights that pop against the rest of the image. Although it displays a wide range of colors, colors aren't as bright as pure white, so some scenes lack punch.

The LG 32GX870B is superb for console gaming. It supports 4k signals up to 120Hz with a PS5 or Xbox Series X|S, but it doesn't support Dolby Vision, which is a downside if you have an Xbox. Motion looks sharp thanks to its near-instantaneous response time, and it has low input lag, ensuring it adds minimal delay to your setup's total latency, which is great for playing games that need fast reactions. It also has fantastic picture quality, especially when playing HDR games. Blacks are deep and inky, highlights pop in dark scenes, and it displays a wide range of colors, but bright colors aren't the most vivid.

The LG 32GX870B is impressive for office use. Its big 32-inch screen helps if you want to place two windows side-by-side, and text looks sharp thanks to its high pixel density. However, its RGWB subpixel layout results in fringing around letters. Fortunately, it gets bright and handles glare well in rooms with overhead lights or lamps nearby, but visibility is an issue in front of a sunny window. Also, it has a wide viewing angle and an ergonomic stand, so it's easy to share the screen with someone next to you. Its USB-C port is also useful if you want to quickly connect a laptop and charge it with one cable. However, it risks burn-in, which is problematic if you constantly have the same static elements displayed without changing things up.

The LG 32GX870B is incredible for content creation. It's remarkably accurate out of the box in its sRGB mode, with a full calibration only slightly improving gamma tracking. It displays a wide range of colors in common color spaces, but bright colors aren't the most vivid, so they lack some punch. It at least has a high contrast ratio for deep blacks in dark rooms. It also performs well in bright rooms as it fights some glare well due to its good brightness and excellent reflection handling, but visibility is an issue in sunny spaces. Unfortunately, it risks burn-in, which is problematic if you constantly have the same static elements displayed without changing things up.

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.
