Monitor ASUS ROG Swift OLED PG32UCDMZ 31,5 inch QD-OLED 3840 x 2160 4K 240Hz, 0,03 ms, DisplayHDR 400 True Black

The ASUS ROG Swift OLED PG32UCDMZ 31.5" QD-OLED 3840 x 2160 is a 31.5-inch flat computer monitor with a 4K Ultra HD resolution of 3840 × 2160 pixels. Its QD-OLED panel combines quantum-dot colour enhancement with OLED pixel control to deliver wide colour gamut and deep black levels. The display features a very fast 0.03 ms response time and a 178° viewing angle for consistent image quality from different positions. Built-in connectivity includes a USB hub with one USB Type-C downstream port (USB 3.2 Gen 1) and the monitor supports VESA mounting with height adjustment for ergonomic placement. The enclosure is finished in black and the monitor does not include integrated speakers.

Advantages

The QD-OLED panel offers vibrant colours and a high typical contrast ratio of 1,500,000:1 for pronounced highlights and deep blacks. The ultra-fast response time of 0.03 ms reduces motion blur in fast-paced content, while the 178° viewing angle maintains colour accuracy when viewed off-centre. Onboard USB 3.2 Gen 1 connectivity and a USB Type-C downstream port simplify peripheral connections. VESA compatibility and height adjustment allow flexible ergonomic installation.

Suitable for

• High-resolution gaming at 4K where fast pixel response is required
• Content creation and colour-critical workflows that benefit from wide gamut and deep black levels
• General office and multitasking setups requiring a large 31.5" workspace
• Ergonomic desk arrangements using VESA mounting and height adjustment

How to use

Position the monitor on a stable desk or install it using a VESA-compatible mount. Connect the display to a video source that supports 4K resolution using an appropriate cable (e.g., DisplayPort or HDMI compatible with the host device) and plug in USB peripherals to the built-in USB hub or the USB Type-C downstream port as required. Use the on-screen display (OSD) menu to adjust brightness, colour settings, and input selection. Adjust the height to a comfortable viewing position to reduce neck strain. Note that the unit does not include speakers, so external audio output is required if sound is needed.

Recommendations

For best visual results, calibrate the display using hardware calibration tools or the available OSD colour presets to match your workflow. When using high-brightness HDR content, monitor energy consumption will increase; consider adjusting HDR and brightness settings to balance picture quality and power usage.
