Key Features 

Ultrafast 255Hz (OC) Refresh Rate and 0.3ms Response Time
An overclocked refresh rate of up to 255Hz is supported to deliver extremely smooth motion, while a minimum response time of 0.3ms is achieved using ASUS Fast IPS technology. As a result, fast-paced competitive games are displayed with reduced ghosting and improved responsiveness.

Fast IPS Panel with WQHD Resolution
A 2560 x 1440 resolution Fast IPS panel is employed to balance sharp image detail with high refresh performance. Wide 178° viewing angles and consistent color accuracy are maintained, making the display suitable for both gaming and multimedia use.

ELMB Sync and Variable Refresh Rate Support
Extreme Low Motion Blur Sync is enabled alongside VRR technologies, allowing motion blur reduction to operate simultaneously with Adaptive-Sync. Screen tearing and stuttering are minimized, even when frame rates fluctuate during gameplay.

G-SYNC Compatible and FreeSync Premium Support
Smooth, synchronized visuals are delivered through compatibility with NVIDIA® G-SYNC and AMD FreeSync Premium. Variable refresh rate technology is applied to reduce tearing and input lag across supported GPUs.

High Dynamic Range with DisplayHDR 400
VESA Certified DisplayHDR 400 support is included to enhance contrast and brightness. Highlights are rendered with improved luminance while darker scenes retain visible detail for a more dynamic image.

Wide Color Gamut and Factory Calibration
A cinema-grade DCI-P3 97% and sRGB 133% color gamut is supported. Each unit is factory checked for color accuracy, ensuring vibrant and consistent visuals suitable for gaming and creative content.

AI-Powered Gaming Enhancements
ROG Gaming A.I features are implemented to enhance on-screen performance. Dynamic Crosshair adapts in real time for improved targeting accuracy, while Dynamic Shadow Boost enhances visibility in dark areas without overexposing bright scenes.

Modern Connectivity with USB Type-C
A USB Type-C port with DisplayPort Alt Mode is provided for video output and power delivery up to 15W. DisplayPort 1.4 and HDMI 2.1 inputs are also included to support high-resolution, high-refresh-rate connections across PCs and consoles.

DisplayWidget Center Software
Monitor settings are adjusted easily through the DisplayWidget Center application, allowing profiles and visual modes to be customized using a mouse instead of physical buttons.

Compact, Ergonomic Design
A compact footprint is used to conserve desk space. The ergonomically designed stand supports tilt, swivel, pivot, and height adjustment, while VESA wall mounting and a built-in 1/4" tripod socket provide additional installation flexibility.
