34-inch QD-OLED ultrawide for competitive play

The 34-inch QD-OLED panel delivers a 3440 x 1440 resolution at a 21:9 aspect ratio with an 1800R curve. A 240 Hz refresh rate and 0.03 ms response time provide the speed required for high-level competitive gaming. DCI-P3 99.3% coverage and 1.07 billion colors ensure accurate, vivid visuals for immersive single-player experiences.

Connectivity and ergonomics built for a clean desk

Video inputs include one DisplayPort 1.4, one USB-C with DisplayPort Alternate Mode, and two HDMI 2.1 ports. A USB 5 Gbps Type-B upstream port enables the monitor’s integrated hub for peripherals. The stand offers height, pivot, swivel, and tilt adjustments so the screen can be positioned precisely without extra mounting hardware.

Steps up from standard IPS ultrawides

The QD-OLED technology replaces traditional backlit panels with per-pixel lighting for a 1,500,000:1 contrast ratio and true blacks. VESA DisplayHDR TrueBlack 400 certification and 1000 nits peak brightness upgrade HDR performance significantly. The jump is worth it when motion clarity, contrast depth, and color volume are priorities over basic high-refresh gaming.

Questions sur cet article

How does the 1,500,000:1 contrast ratio hold up during long HDR sessions?

The QD-OLED panel maintains its 1,500,000:1 contrast ratio continuously because each pixel emits its own light, so black levels do not degrade even after hours of HDR400 content at up to 1000 nits peak brightness.

What are the thermal and acoustic characteristics when the monitor runs at 240 Hz all day?

The display operates silently with no fans; heat is dissipated passively through the rear vents, and the panel temperature stays within normal OLED limits during continuous 240 Hz use.

Which cables and ports must my PC already provide to use every feature?

You need a graphics card with DisplayPort 1.4 or HDMI 2.1 for 3440 x 1440 at 240 Hz, plus a USB-C port with DisplayPort Alt Mode if you want the single-cable video and 5 Gbps USB upstream connection.
