Display and Resolution

The 27 inch panel uses a native 3840 x 2160 4K at 160Hz or 1920 x 1080 Full HD at 320Hz resolution. This provides detailed images and useful desktop space for supported games, applications, media and multitasking.

The 16:9 aspect ratio provides broad compatibility with modern PC, console and video content.

Smooth and Responsive Performance

The 160Hz in 4K mode and 320Hz in Full HD mode refresh capability allows the display to update the image rapidly when paired with compatible hardware and the correct connection. Higher refresh rates can improve motion clarity and make cursor movement, camera panning and gameplay feel smoother.

A response time of 1ms Grey to Grey helps reduce visible ghosting and motion blur around fast-moving objects. This is especially valuable in competitive games, racing titles and other fast-paced content.
