Display and Resolution

The 27 inch panel uses a native 2560 x 1440 QHD 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 240Hz 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 0.03ms 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.

Panel and Image Quality

The OLED with glare coating panel is selected to balance image quality, colour presentation and motion performance for the intended use of this monitor.

Core image specifications include contrast: 1,500,000:1; colour gamut: 98.5 percent DCI-P3.

VESA DisplayHDR True Black 400 support allows compatible games, videos and applications to use an expanded range of brightness and colour information. HDR results depend on the content, operating system settings, graphics hardware and selected picture mode.

Variable Refresh Rate

AMD FreeSync Premium Pro, NVIDIA G-SYNC compatible operation and Adaptive Sync allows the monitor to coordinate its refresh behaviour with a compatible graphics card. This can reduce visible screen tearing and minimise stuttering when the rendered frame rate changes.
