Pros & Cons

Pros

  • ✓ QD-OLED panel hits 0.03ms response, effectively zero motion blur in fast shooters
  • ✓ 240 Hz at 1440p leaves headroom for competitive esports frame rates
  • ✓ Neo Proximity Sensor blanks the screen when you step away, cutting burn-in risk
  • ✓ 99% DCI-P3 with true 10-bit color and Delta E under 2 for accurate HDR
  • ✓ DisplayWidget Center app changes OLED Care Pro settings by mouse, not OSD joystick

Cons

  • ✗ Actual visible area is 26.5 inches, smaller than the 27-inch marketing figure
  • ✗ 1440p ceiling means no native 4K for single-player or productivity work
  • ✗ OLED burn-in still needs care habits despite the Care Pro suite
  • ✗ G-SYNC Compatible rather than full hardware G-SYNC module certification

Manufacturer description

The ROG Strix OLED XG27AQDMES is a 27" 240Hz QHD gaming monitor. The state-of-the-art QD OLED panel offers longer life 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 switches to a black screen when no user is detected and protects against burn-in.
