31.5" 4K QD-OLED gaming monitor

The MPG 322UR QD-OLED X24 is a 31.5-inch UHD display built for competitive gaming and colour-critical work. A 240 Hz refresh rate and 0.03 ms response time deliver fluid motion, while the QD-OLED panel covers 99 % DCI-P3 and 138 % sRGB for vivid, accurate colour.

Capacity and headroom

4K resolution at 240 Hz fits high-frame-rate esports titles and detail-heavy single-player games alike. The 1,500,000:1 contrast ratio and DisplayHDR True Black 500 certification provide deep blacks and bright highlights, though sustained full-screen brightness tops out at 300 cd/m², limiting peak HDR impact in very bright scenes.

Thermals, noise and power

The 5-layer Tandem OLED architecture improves light efficiency by 30 %, reducing panel heat during extended sessions. No active cooling is present, so operation stays silent. AI Care Sensor detects user absence and triggers OLED protection measures to minimise burn-in risk during idle periods.

Questions about this item

Will the DisplayPort 2.1a port run 4K at 240Hz with my existing graphics card?

The DisplayPort 2.1a interface supports the full 3840 x 2160 resolution at 240Hz. Your graphics card must also support DisplayPort 2.1 or DisplayPort 1.4 with DSC to deliver that signal without compression artefacts.

How can I verify the panel is hitting the 0.03 ms response time and 240Hz refresh rate in games?

Enable the on-screen display refresh-rate counter and run a motion-clarity test pattern; smooth motion at 240 frames per second with no visible ghosting confirms the 0.03 ms response and 240Hz operation.

Which cables are included and what must I buy separately for the USB hub?

The box contains the monitor, stand, power cable, one DisplayPort cable, one HDMI cable and one USB Type-B upstream cable; the USB-C cable for DP Alt Mode or charging is not included.
