The ASUS ROG Strix XG34WCDMS is a 34-inch curved ultrawide QD-OLED gaming monitor with 3440 × 1440 resolution, a 280Hz refresh rate, and 0.03ms response time, suited to players who want a wide, smooth display for fast-paced PC gaming.
Recommended For
- PC gamers who want a wide, immersive view for racing games and cinematic single-player titles, with OLED contrast and smooth motion at up to 280Hz.
- Competitive PC gamers who want very fast OLED response and refresh rates, and whose games and graphics card can make use of a 3440 × 1440 ultrawide display at high frame rates.
- Multitaskers who prefer a single wide desktop for side-by-side documents, spreadsheets, or editing panels, and value improved text clarity compared with older QD-OLED pixel layouts.
- PC users who want an OLED gaming display with color-focused features for hobby photo or video work, while accepting a 34-inch 21:9 screen rather than a dedicated reference display.
