LG unveils 32GX870B, a 32-inch 4K 240 Hz Tandem OLED monitor with 480 Hz mode

LG has introduced another 4th-Gen WOLED monitor to be showcased alongside its trio of new UltraGear evo 5K gaming displays at CES 2026. This time, the company is expanding its Tandem OLED lineup with a 32-inch 4K model called the UltraGear evo 32GX870B. To recap, the 4th-Gen Primary RGB Tandem OLED panel originally debuted in 1440p monitors like the Gigabyte MO27Q28G. The 32GX870B will be the first 4K gaming monitor built around the new four-stack OLED structure.

LG has not shared full specs yet, but a few details are already confirmed. The 32GX870B runs at a native 4K resolution on a 32-inch panel, which works out to about 138 PPI and makes it noticeably sharper than a 27-inch 1440p monitor at roughly 109 PPI. LG also lists 99.5% DCI-P3 coverage and DisplayHDR True Black 500, which is in line with what we have seen from other Tandem OLED monitors so far.

Another major highlight is the refresh rate. LG says the 32GX870B can run at a native 240 Hz at 4K, and it can jump to 480 Hz at 1080p. The monitor also supports AI-powered upscaling, which should help lower-resolution content look closer to 4K. In terms of connectivity, the monitor is listed with DisplayPort 2.1, HDMI 2.1, and USB-C with 90 W Power Delivery. Gamers should be able to hit the maximum refresh rate through DisplayPort without DSC. Unfortunately, LG has not shared any pricing or availability details at this point.
