Specifications

26.5″ QD-OLED Display

At the heart of the ROG Strix OLED XG27AQDMES is its 26.5-inch QD-OLED panel.

Unlike conventional LCD gaming monitors, OLED displays don't depend on a separate LED backlight. Individual pixels generate their own light and can switch off independently, producing exceptionally deep blacks and high contrast.

QD-OLED technology combines this pixel-level control with quantum-dot color conversion, making the monitor particularly attractive for users who value vibrant colors alongside OLED's outstanding contrast.

2560 × 1440 QHD Resolution

The XG27AQDMES delivers a native 2560 × 1440 resolution.

QHD provides significantly more screen detail than 1920 × 1080 while remaining easier to drive at very high frame rates than 4K UHD. On a 26.5-inch display, it provides an excellent combination of sharpness, desktop space, and gaming performance.

It's particularly well suited to powerful gaming PCs where maintaining high FPS is just as important as image quality.

Ultra-Fast 240Hz Refresh Rate

With a maximum refresh rate of 240Hz, the XG27AQDMES can display up to 240 refreshed frames each second when paired with compatible hardware and settings.

The increased refresh rate is especially valuable in fast-paced games such as:

• Counter-Strike 2
• VALORANT
• Call of Duty
• Overwatch
• Apex Legends
• Fortnite
• Rainbow Six Siege
• Racing Games

For competitive gamers, the combination of 240Hz and OLED response characteristics provides exceptionally clear and responsive motion.

0.03ms GTG Response Time

OLED's extremely fast pixel transitions allow the XG27AQDMES to achieve a rated 0.03ms GTG response time.

This is considerably faster than typical LCD gaming monitors and helps minimize visible ghosting and motion smearing during rapid camera movements.

Combined with the 240Hz refresh rate, it makes the monitor particularly well suited to competitive FPS and esports gaming.

Deep OLED Blacks & High Contrast

Because every OLED pixel can control its own illumination, black areas of an image can be displayed with the pixels effectively switched off.

This provides:

• Deep blacks
• Excellent dark-scene detail
• High perceived contrast
• Precise highlights
• No conventional backlight glow
• Strong image depth

These characteristics benefit atmospheric single-player games just as much as competitive titles.

HDR10 Gaming

The XG27AQDMES supports HDR10, allowing compatible PCs, consoles, games, and media to display HDR content.

OLED's pixel-level lighting control is particularly advantageous for HDR scenes containing bright highlights alongside very dark backgrounds, such as explosions, lights, stars, and reflections.

Adaptive-Sync Technology

Variable refresh rate support allows the monitor's refresh cycle to synchronize dynamically with the frame output from a compatible graphics system.

This helps minimize:

Screen tearing – when portions of multiple frames appear simultaneously.

Stuttering – inconsistent frame presentation caused by mismatched GPU and monitor timing.

The result is smoother gameplay when frame rates fluctuate below the monitor's maximum 240Hz refresh rate.

Anti-Reflection Display

The XG27AQDMES incorporates an anti-reflection screen treatment, helping reduce distracting reflections from lamps, windows, and other environmental light sources.

This is especially useful for OLED displays used in gaming rooms that aren't completely dark.

ASUS OLED Care

OLED displays require additional consideration around long-term static content, so ASUS integrates OLED Care technologies designed to help protect the panel.

These features are intended to reduce the likelihood of image retention associated with extended display of static interface elements such as taskbars, HUDs, icons, and application windows.

For PC users who alternate between gaming and desktop productivity, these protection features are an important part of the overall OLED experience.

Ideal for Competitive & Immersive Gaming

The XG27AQDMES sits in an attractive performance category by combining:

QD-OLED image quality for immersive games
QHD resolution for excellent detail
240Hz refresh rate for competitive gaming
0.03ms response time for exceptional motion clarity

This makes it a versatile choice for gamers who play both competitive multiplayer titles and graphically rich single-player games.
