The combination of G-Sync Compatible, AMD FreeSync Premium, and Adaptive-Sync technologies eliminates screen tearing by synchronising with your graphics card. Extreme Low Motion Blur Sync technology enables motion blur reduction and variable refresh rate to run simultaneously. Variable Overdrive 2.0 dynamically adjusts the panel's overdrive settings as frame rates fluctuate, maintaining optimal image sharpness at all times.
AI-powered gaming assistance
ROG Gaming A.I. technology brings intelligent features to assist in gaming situations. Dynamic Crosshair analyses the on-screen scene in real time and adjusts the reticle colour to improve visibility. Dynamic Shadow Boost brightens dark corners in the game without overexposing bright areas, making it easier to spot hidden enemies in dark game locations.
Ergonomics and physical stand adjustments
The ergonomic stand makes it easy to adjust the screen position for high comfort during long gaming sessions. You can adjust the height from 0 to 160mm, tilt from -5° to +20°, and swivel from -45° to +45°. The pivot function lets you rotate the screen 90° in both directions for vertical viewing. In addition, the design includes a practical 1/4" tripod thread and supports wall installation using a standard VESA 100×100 mount.
Eye protection for extended use
ASUS ROG Strix XG259QNSR 24.5" monitor uses certified technologies to reduce eye fatigue during long work or gaming sessions. The Flicker-free system removes imperceptible backlight flickering that strains your eyes. The integrated Low Blue Light filter reduces emissions of the harmful spectrum, protecting your vision from fatigue and contributing to better sleep quality after evening gaming.
Simple control with DisplayWidget Center
Forget struggling with mechanical buttons on the back of your monitor. The accompanying DisplayWidget Center application enables complete management of settings and display profiles directly within your operating system using a standard computer mouse. You can adjust colour, brightness, or gaming features in just a few seconds without interrupting your work.

Colour gamut
Determines how accurately the monitor displays colours. sRGB is ideal for web browsing, movies or gaming. Graphic designers or professionals will appreciate DCI-P3/Adobe RGB. The higher the value, the better the monitor displays colours.
Maximum brightness
The value given in nits or cd/m² determines the brightness level of the monitor. Brightness above 400 nits is key for HDR content and legibility in sunlight, while standard office monitors require values above 250.
Refresh rate and response time
The refresh rate (Hz) determines the number of frames displayed per second, so the higher the value, the smoother the image and the less eye fatigue. A lower response time (ms) eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
