27-inch QHD QD-OLED gaming monitor
The ASUS ROG Strix XG27AQDMES is a 26.5-inch QHD QD-OLED gaming monitor built for competitive players who demand speed and colour accuracy. Its 2560 x 1440 resolution pairs with a 240Hz refresh rate and a 0.03ms response time for motion clarity in fast titles. The panel covers 99% DCI-P3 and delivers true 10-bit colour with Delta E < 2 calibration. FreeSync Premium Pro and G-Sync Compatible adaptive sync keep frame delivery smooth.
Thermals noise and power draw
Typical power consumption stays below 25W, dropping under 0.5W in power-saving mode and under 0.3W when off. The OLED panel runs without a cooling fan, so operation is silent during normal use. An integrated Neo Proximity Sensor detects when you step away and switches the screen to a black image, reducing heat output and burn-in risk automatically. The external power supply accepts 100-240 VAC at 50/60Hz.
Bundled accessories and software
The box includes a DisplayPort 1.4 cable, two HDMI 2.1 cables, a microfibre cloth, a ROG pouch and sticker, a VESA 100 x 100mm mount kit and the quick-start guide. DisplayWidget Center lets you adjust OLED Care Pro settings and monitor parameters with a mouse instead of the OSD joystick. ROG Gaming A.I. adds AI-powered features designed to enhance the gaming experience. A complimentary three-month Adobe Creative Cloud subscription is included, valid until 08/31/2026.

Questions about this item
How do I set up the height-adjustable, swivel, pivot and tilt stand and what step do people miss?
Attach the stand neck to the monitor arm using the quick-release latch, then secure the base with the captive thumbscrew; the step often missed is locking the latch fully until it clicks before tightening the thumbscrew.
What maintenance will the QD-OLED panel need over time?
The built-in OLED Care Pro with Neo Proximity Sensor runs automatic pixel cleaning and screen-saver cycles when you step away; run a manual pixel refresh from the OSD or DisplayWidget Center after extended static content.
What limit appears first during long gaming sessions at 240 Hz?
The 200 cd/m² peak brightness caps HDR highlight detail before thermal throttling becomes a factor.
