34" UWQHD 200Hz gaming monitor

This 34-inch VA panel delivers UWQHD resolution at a 200Hz refresh rate. Adaptive Sync matches the display to the GPU for tear-free motion. The 21:9 aspect ratio suits immersive gaming and multitasking alike. A 0.5ms GTG response time keeps fast action sharp.

Thermal performance and power

The monitor runs at a typical brightness of 300 cd/m² with a 4000:1 contrast ratio. Non-glare coating reduces reflections during long sessions. No active cooling is present so operation stays silent. Power draw scales with the selected refresh mode.

Dual-mode and AI switching

Dual-mode lets the panel run at UWQHD 200Hz or drop to a lower resolution for a 400Hz refresh rate. MSI AI Dual Mode detects the resolution change and adjusts the refresh rate automatically without a trip to Windows settings. SLMB Sync reduces ghosting while variable refresh rate remains active. The stand provides tilt adjustment and the cabinet includes one DisplayPort 1.4a and two HDMI 2.0b inputs.
