Overview
The LG 32GX870B pairs a 31.5-inch OLED panel at 3840 × 2160 with a refresh rate of up to 240 Hz. It offers 140 ppi pixel density, 335 nits typical brightness (1500 nits peak) and 99.5% DCI-P3 coverage. Variable refresh covers 48–240 Hz, quotes 0.03 ms response and supports FreeSync Premium Pro and G-Sync. Inputs include 2× HDMI 2.1, 1× DisplayPort 2.1, USB-C 90 W and 2× USB-A. The stand offers 110 mm of height adjustment, swivel and pivot. 2 × 7 W speakers are built in, and it weighs 9.8 kg with the stand. It suits players who want OLED contrast with very fast response.
