Overview
Aimed at gamers, the Asus ROG Strix OLED XG27ACDMS is a 26.5-inch QD-OLED display with a 2560 × 1440 panel that refreshes at up to 280 Hz. It offers 110 ppi pixel density, 250 nits typical brightness (1000 nits peak) and 99% DCI-P3 coverage. Variable refresh covers 48–280 Hz, quotes 0.03 ms response and supports FreeSync Premium Pro and G-Sync. Inputs include 1× HDMI 2.1, 1× DisplayPort 1.4 and USB-C 15 W. The stand offers 110 mm of height adjustment, swivel and pivot. There are no speakers, and it weighs 6.1 kg with the stand. It suits players who want OLED contrast with very fast response. The main trade-off: USB-C output is only 15 W, too little to charge most laptops.
