The ROG Strix XG129C is engineered to be the perfect secondary display—ready to seamlessly slide underneath a primary monitor to upgrade the overall desktop experience. Unlike ultrawide 32:9 portable screens, the XG129C utilizes a highly optimized 12.3-inch 24:9 (1920 x 720) IPS panel. This specific ratio minimizes black bars along the top and bottom of the display, offering a more generous vertical viewing area. Its 10-point touch control provides smooth, precise multi-finger input for quick OSD interaction, hotkey execution, and app management during intense gaming or streaming sessions.To ensure consistent visuals across a multi-monitor setup, the XG129C boasts exceptional color performance, covering 125% of the sRGB and 90% of the DCI-P3 color gamuts, to match the vibrant output of premium primary displays. And to empower hardware enthusiasts keen on keeping a close eye on system performance, the XG129C includes a bundled one-year subscription to AIDA64 Extreme. This pairs perfectly with two exclusive ROG SensorPanel interfaces to transform the screen into a dedicated, real-time hardware monitoring dashboard. It is also fully supported by the ASUS DisplayWidget Center and ASUS Control Panel for intuitive, immediate setting adjustments.

Connectivity and physical design are equally refined to keep desktops pristine. A hybrid-signal USB-C port handles power, video, and touch data simultaneously through a single cable. A secondary USB-C port offers 20 W Power Delivery, while an HDMI 1.2 port ensures broad compatibility with PCs and other devices. All this functionality is housed in a sleek chassis that measures just 6.3 mm at the panel, and a built-in adjustable kickstand and standard tripod socket offer maximum mounting versatility.
