34" UWQHD QD-OLED gaming monitor

The MPG 341CQPX QD-OLED is a 34-inch ultrawide display built around a QD-OLED panel with a 3440 x 1440 resolution and a 21:9 aspect ratio. Its 1800R curvature wraps the image for an immersive field of view. G-Sync Compatible adaptive sync keeps frames tear-free. The panel produces 1.07 billion colours with 10-bit depth and covers 97.8% Adobe RGB, 99.3% DCI-P3 and 139.1% sRGB.

240Hz refresh and 0.03ms response headroom

A native 240Hz refresh rate combined with a 0.03ms GTG response time delivers smooth motion for competitive FPS and racing titles. Brightness reaches 250 nits in SDR, 450 nits typical in HDR and peaks at 1000 nits with a 3% APL window. The 150,000:1 contrast ratio and DisplayHDR True Black 400 certification provide deep blacks, though full-screen HDR brightness is limited to the 450-nit typical level.

HDMI 2.1 and USB-C 98W PD connectivity

Dual HDMI 2.1 ports supply 48Gbps bandwidth with 120Hz console support, VRR and ALLM. DisplayPort 1.4a handles the full 240Hz on PC. The USB-C input carries DP Alt Mode video and up to 98W power delivery for a laptop. ClearMR 13000 certification and OLED Care 2.0 with a 24-hour refresh cycle further define the monitor’s capabilities.

Questions about this item

Will the 240Hz 0.03ms QD-OLED panel work properly with my older GPU that only has HDMI 2.0 and DisplayPort 1.2?

The monitor includes HDMI 2.1 and DisplayPort 1.4a inputs; an older GPU with HDMI 2.0 or DP 1.2 will still output a signal but you will be limited to lower refresh rates and may not reach the full 240Hz at 3440x1440.

How can I verify the panel is delivering the advertised 240Hz refresh rate and 0.03ms response time once I have it set up?

Enable the on-screen refresh-rate counter in the monitor menu and confirm it reads 240Hz; then run the UFO test at testufo.com to visually check motion clarity at that frame rate.

What cables and accessories come in the box, and do I need to buy anything extra for 98W USB-C power delivery or the KVM function?

The package includes the monitor, stand, power cable, DisplayPort cable, HDMI cable, USB-C cable and USB-B upstream cable; no extra purchase is required for 98W PD or KVM operation.
