The ROG Strix OLED XG27UCDMG is a 27-inch, 240Hz 4K gaming monitor that boasts the latest fourth-generation QD-OLED technology to deliver supersharp visuals and crisp text. 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.
