The Asus ROG Strix XG27ACMES pairs a 27-inch IPS panel at 2560 × 1440 with a refresh rate of up to 255 Hz.
Overview
The Asus ROG Strix XG27ACMES pairs a 27-inch IPS panel at 2560 × 1440 with a refresh rate of up to 255 Hz. It offers 109 ppi pixel density, 350 nits typical brightness (400 nits peak), 1300:1 static contrast and 133% sRGB and 97% DCI-P3 coverage. Variable refresh covers 48–255 Hz, quotes 1 ms response and supports FreeSync Premium 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 5.96 kg with the stand. It suits competitive players who put frame rate first. The main trade-off: USB-C output is only 15 W, too little to charge most laptops.
