Computer monitor ASUS ROG Strix OLED XG32UQDMS 31.5 inch 3840 x 2160 4K OLED, 0.03 ms, USB 3.2 Gen 1, VESA, height adjustable, black

The ASUS ROG Strix OLED XG32UQDMS is a 31.5" 4K (3840 x 2160) QD‑OLED monitor designed for high‑fidelity gaming, content creation and productivity tasks where color accuracy, contrast and low latency are important. It features a flat OLED panel with a 16:9 aspect ratio, 250 cd/m² typical brightness, 178°/178° viewing angles, a 240 Hz refresh rate and an ultra‑fast 0.03 ms (GTG) response time. The monitor includes an integrated USB 3.2 Gen 1 hub, VESA mounting support and height adjustment. ASUS OLED Care Pro functions with a Neo Proximity Sensor help reduce burn‑in risk by switching to a black screen when no user is detected.

Advantages

The QD‑OLED panel delivers deep blacks, wide color gamut and true 10‑bit color for accurate, vivid images and reliable HDR performance. A 240 Hz refresh rate combined with 0.03 ms response time minimizes motion blur and input latency for smooth, responsive gameplay. Built‑in features such as the Neo Proximity Sensor and optional uniform brightness setting provide additional control to protect the panel and maintain consistent luminance. Integrated USB connectivity and ergonomic height adjustment make the monitor adaptable to different setups.

Suitable for

• Competitive and fast‑paced PC gaming
• Color‑critical content creation and photo/video editing
• General productivity and multitasking with high‑resolution workspace
• Users who need a VESA‑mountable, height‑adjustable display

When it may not be suitable

This monitor’s typical brightness of 250 cd/m² and VESA DisplayHDR 400 True Black classification provide improved HDR contrast but may not reach the peak luminance of higher‑end HDR displays aimed at professional mastering. The panel does not include built‑in speakers, so a separate audio solution is needed for sound.

How to use

Connect the monitor to your PC using a compatible video cable that supports 4K at high refresh rates (check GPU and cable specifications). Use the monitor on‑screen display or DisplayWidget Center to enable OLED Care functions, adjust color settings, toggle uniform brightness and configure adaptive sync. Adjust the stand height for ergonomic viewing; if needed, mount the monitor using a VESA‑compatible arm. For optimal gaming performance, match the in‑game refresh rate to the monitor’s 240 Hz capability and enable G‑SYNC or FreeSync in your GPU settings.

What to consider before purchase

• Confirm your graphics card and cables support 4K at 240 Hz to take full advantage of the panel
• Plan for external audio if speakers are required, since the monitor has no built‑in speakers
• Consider room lighting and workflow—typical brightness is 250 cd/m², which affects perceived HDR highlights
• Account for energy consumption class and typical power usage in your setup

Recommendations

Use the Neo Proximity Sensor and OLED Care Pro settings to reduce static content time and enable uniform brightness when working with still images; keep firmware and GPU drivers updated to ensure compatibility with high refresh rate and adaptive sync features.
