LG Electronics is preparing to unveil its first 32-inch 4K gaming monitor based on its latest Tandem OLED technology at CES 2026, expanding a panel lineup that until now has been limited to lower resolutions.
The new model, branded as the UltraGear evo 32GX870B, will be the first 4K gaming display built on LG’s fourth-generation Primary RGB Tandem OLED structure. The panel will be presented alongside LG’s new UltraGear evo 5K gaming monitors at the annual technology trade show in Las Vegas.

LG said the monitor features a native 4K resolution on a 32-inch screen, delivering higher pixel density than existing 27-inch 1440p gaming displays. The company has also confirmed 99.5% coverage of the DCI-P3 color space and support for DisplayHDR True Black 500, specifications consistent with other Tandem OLED panels. As outlined in the announcement, the display is based on a “new four-stack OLED structure.”
A key feature of the 32GX870B is its high refresh rate. LG said the monitor supports 240 Hz at native 4K resolution and can reach up to 480 Hz when scaled down to 1080p. The display also includes AI-powered upscaling, designed to improve the appearance of lower-resolution content on the 4K panel.
