ASUS ROG Strix OLED XG27AQDMG gaming monitor 26.5 inch 2560x1440 WOLED 0.03 ms USB 3.2 Gen 1 VESA height-adjustable, black

The ASUS ROG Strix OLED XG27AQDMG is a 26.5-inch WOLED gaming monitor with a 2560×1440 (Wide Quad HD) resolution, glossy panel surface and an ultra-fast 0.03 ms gray-to-gray response time. It features a 240 Hz refresh rate, wide 178° viewing angles, a built-in USB 3.2 Gen 1 hub, VESA mount compatibility and a height-adjustable stand. The monitor is designed for high-contrast visuals and fast-paced gameplay while incorporating thermal and panel-care measures to extend OLED lifespan.

Advantages

The glossy WOLED panel delivers deep blacks, bright whites and high contrast for detailed HDR-like imagery, while a 240 Hz refresh rate and 0.03 ms response time minimise motion blur and ghosting in fast action. An efficient custom heatsink and advanced airflow help maintain stable operating temperatures, and ASUS OLED Care functions plus OLED Anti-flicker technology reduce the risk of burn-in and flicker during refresh-rate changes. Built-in USB connectivity and a height-adjustable, VESA-compatible stand add practical ergonomics for desktop setups.

Suitable for

• Competitive and fast-paced gaming (FPS, racing, esports)
• High-contrast multimedia and video playback
• Users who need a glossy WOLED panel for deeper blacks and vivid highlights
• Desktop setups that require USB hub access and adjustable ergonomics

When it may not be suitable

The glossy surface can produce reflections in bright or uncontrolled lighting, which may be distracting for some users. The monitor does not include built-in speakers, so an external audio solution is required for sound. Energy efficiency ratings indicate relatively higher power use compared with some LED/LCD alternatives.

How to use

Position the monitor on a stable desk or mount it using a compatible VESA arm, adjust the height to achieve comfortable eye level and connect your PC or console via DisplayPort or HDMI. Use the built-in USB 3.2 Gen 1 hub to attach peripherals. Access ASUS DisplayWidget Center software or the on-screen display to enable OLED Care functions, set uniform brightness if desired, and activate OLED Anti-flicker to reduce refresh-rate flicker. For best image quality, calibrate brightness and colour settings for your environment and avoid prolonged static high-contrast content to reduce burn-in risk.

What to consider before purchase

• Glossy WOLED surface may reflect ambient light; consider your room lighting
• No built-in speakers — external audio required if sound is needed
• Power consumption is higher than some LED monitors; check energy use expectations
• OLED panels benefit from using manufacturer care features to minimise burn-in risk

Recommendations

Use the ASUS OLED Care functions and optional uniform brightness setting, enable OLED Anti-flicker during mixed refresh-rate scenarios, and avoid leaving static high-contrast images displayed for extended periods to preserve panel longevity. Adjust monitor height and viewing angle to reduce reflections on the glossy surface.
