Product information

Description

The ASUS ROG Strix OLED XG27UCDMG is a 26.5" 4K Ultra HD monitor with QD‑OLED panel technology and a native resolution of 3840 x 2160. The display has a 16:9 aspect ratio, a flat screen and a very fast 0.03 ms response time. It supports wide 178° viewing angles and includes a built‑in USB hub, headphone output and VESA mounting compatibility for flexible setup.

Advantages

QD‑OLED panel delivers high contrast and vivid color reproduction while the extremely low response time minimizes motion blur for fast-moving content. The monitor’s 4K resolution provides detailed imagery suitable for gaming and multimedia, and VESA support plus a built‑in USB hub simplify installation and peripheral connections. Energy consumption values are specified for both SDR and HDR usage.

How to use

Place the monitor on a stable surface or attach it to a compatible VESA mount.

Adjust display settings using the on‑screen menu to select preferred picture modes, refresh rate and color calibration according to the connected device and content type.

Usage recommendations

For optimal image quality and motion performance, use a graphics card and cables that support 4K at high refresh rates. Calibrate color settings for color‑critical work and allow adequate ventilation around the monitor to prevent heat buildup during prolonged HDR use.
