About this product

ONE FOR ALL

The ROG Strix OLED XG27AQDMES is a 27-inch, 240Hz QHD gaming monitor. The cutting-edge QD-OLED panel offers greater longevity compared to previous OLED technologies and minimal flicker―even when frame rates fluctuate. With the addition of the Neo Proximity Sensor in the new ROG OLED Care Pro suite, the monitor transitions to a black screen when no user is detected, guarding against burn-in.
