Wide QHD (WQHD) Resolution

The widescreen 21:9 aspect ratio is perfect for watching movies in an expansive format or immersing yourself in the latest game, plus it offers more space when it’s time to work. True 8-bit color provides a broad color palette for vibrant, natural-looking images.
1500R Curved
Curved design wraps around you putting you at the center of the action and provides an immersive gaming experience.
250Hz Refresh Rate
Whether you immerse yourself in fast action movies, edit quick-moving videos or play competitive games, less blurry motion and fast screen response create smooth, realistic pictures that show you what a truly clear display looks like.
Fast VA
Immerse yourself in a world of deeper blacks and striking contrast. Vivid, bright visuals bring your games to life like never before.
Vesa Certified DisplayHDRTM 400
Even the lowest level of High Dynamic Range (HDR) feature poses a significant upgrade to common monitors. The peak luminance of 400 cd/m2 enables your display to hone the picture quality with a manifold colour spectrum and more diverse contrast. The VESA-certificate ensures richness of detail and realistic portrayals of game and film worlds.
Adaptive sync
Adaptive Sync aligns your monitor’s vertical refresh rate with the frame rate delivered by your GPU, making your gameplay and casual gaming experience even more fluid by eliminating stuttering, tearing and judder. This feature is also useful when enjoying videos and other visual media, for a smoother entertainment.
