34-Inch UWQHD QD-OLED Gaming Experience

The 3440 x 1440 UWQHD resolution provides a wide 21:9 workspace with detailed visuals across the 34-inch curved display. The ultrawide format provides additional horizontal screen space for immersive games, racing simulations, strategy titles, multimedia, and productivity workflows.

280Hz Refresh Rate and 0.03ms Response Time

The 280Hz refresh rate provides highly fluid motion for fast-paced gaming when the connected hardware can deliver sufficiently high frame rates. Combined with the 0.03ms GTG response time of the QD-OLED panel, the monitor is designed to minimize motion blur and ghosting during rapid on-screen movement.

Tandem RGB QD-OLED Technology

The XG34WCDMS uses Tandem RGB QD-OLED technology, combining OLED contrast with Quantum Dot color reproduction. ASUS specifies 99% DCI-P3 coverage, 10-bit color, ΔE ≤ 2 color accuracy, and a 1,500,000:1 typical contrast ratio for detailed and vibrant visuals.

1800R Curved Ultrawide Display

The 1800R curvature brings the edges of the 21:9 display closer to the user's natural field of view. This design is particularly suited to immersive gaming, racing simulations, widescreen entertainment, and multitasking across multiple applications.
