34" curved OLED screen in 21:9 format
The ASUS ROG Strix OLED XG34WCDG combines extreme performance, a high-end panel and innovative features. Its ultra-wide curved design and QD-OLED technology immerse you in total immersion, while its intelligent tools protect your screen over time.
Picture quality and fluidity
With its 34-inch QD-OLED panel featuring 3440 × 1440 resolution and 1800R curvature, the XG34WCDG delivers enhanced immersion worthy of the cinema. Its 175 Hz refresh rate combined with an ultra-fast response time of 0.03 ms (greyscale) ensures smooth, responsive images with no motion blur, enhanced by exclusive Extreme Low Motion Blur technology.
For designers, photographers or videographers, 99.3% coverage of the DCI-P3 gamut, true 10-bit colour and a delta E < 2 ensure exemplary colour fidelity. Finally, G-SYNC and AMD FreeSync Premium Pro compatibility guarantees stable, tear-free rendering, even in the most intense action scenes.
Comfort and modern connectivity
To ensure the longevity of the OLED panel, ASUS has equipped this model with the OLED Care Pro suite: the Neo proximity sensor detects your absence and triggers a black screen to avoid the risk of screen burn-in. You'll also benefit from a customised heatsink, optimised internal airflow, uniform brightness adjustment and intuitive DisplayWidget Center software to manage all settings via mouse.
In terms of ergonomics, the USB-C socket with 15W PD, integrated tripod socket for efficient streaming, space-saving base, height/tilt/rotation adjustment and VESA 100×100 support ensure a smooth, customisable installation.
