Product Overview
The ASUS ROG Strix OLED XG34WCDMS delivers an immersive ultrawide gaming experience through its 34-inch Tandem RGB QD-OLED display. The 1800R curved panel features a 3440 × 1440 UWQHD resolution and 21:9 aspect ratio, providing additional horizontal viewing space for gaming, content creation and multitasking.
A rapid 280Hz refresh rate and ultra-low 0.03ms GTG response time deliver exceptionally clear motion during competitive and fast-paced games. Support for AMD FreeSync Premium Pro and NVIDIA G-SYNC compatibility helps minimise tearing and stuttering when paired with supported graphics hardware.
The RGB-stripe subpixel arrangement improves text clarity and colour reproduction, while ASUS BlackShield film provides increased scratch resistance and deeper perceived black levels. The display supports true 10-bit colour, covers 99% of the DCI-P3 gamut, and is factory calibrated to achieve a Delta E of less than 2. VESA DisplayHDR 500 True Black certification enables deep blacks, brilliant highlights and excellent HDR contrast. RGB Stripe Pixel OLED
