The Asus ROG Strix XG309CM is engineered for gamers who demand both immersion and extreme speed. Featuring a 29.5-inch ultra-wide panel with a 2560 x 1080 resolution, this monitor provides a 21:9 aspect ratio that expands your field of view in games and offers significantly more desktop real estate for multitasking and productivity compared to standard 16:9 displays. Performance is at the core of the XG309CM. Utilizing ASUS Fast IPS technology, the display achieves a 1ms GTG response time, virtually eliminating motion blur and smearing. For the most demanding titles, the monitor can be overclocked to a massive 220Hz refresh rate, ensuring fluid visuals in first-person shooters, racing, and sports games. This is further enhanced by ELMB SYNC technology, which eliminates ghosting and tearing by combining Extreme Low Motion Blur with variable refresh rate support. Designed with the modern streamer and power user in mind, the monitor includes a unique 1/4-inch tripod socket on the stand, allowing you to mount a camera or additional display directly to your setup. The integrated KVM switch allows you to control two connected devices using a single keyboard and mouse, reducing desk clutter and streamlining your workflow. Connectivity is versatile and modern. A USB Type-C hub supports DisplayPort signal transmission and provides up to 15W of power delivery to charge mobile devices. For visual fidelity, the monitor covers 110% of the sRGB color gamut and includes HDR support, while Shadow Boost clarifies dark areas of the game world without overexposing bright spots. Build quality is matched by ergonomic flexibility. The stand offers comprehensive tilt, swivel, and height adjustments to ensure the perfect viewing angle, and the chassis is VESA-compatible (100 x 100 mm) for those who prefer wall mounting. Aura Sync lighting adds a final touch of ROG style, allowing the monitor to synchronize with your other RGB peripherals.
