Resolution and Screen Space

The native 2560 x 1440 QHD resolution determines available workspace and graphics load. Higher resolutions sharpen text and fine detail, while ultrawide formats provide additional horizontal space for timelines, multiple windows and immersive games.

Refresh Rate and Motion

A maximum refresh rate of 240Hz allows the screen to update more frequently than a standard 60Hz display. The listed 0.03ms class response rating helps reduce visible trailing. The chosen cable, input and graphics hardware must support the intended mode.

Panel Technology

The OLED panel is selected for this model's intended use. OLED technology provides exceptional black levels, contrast and pixel response. Panel-care functions should remain enabled, and long periods of static content should be avoided where practical.

Adaptive Synchronisation

Adaptive Sync can reduce tearing and uneven frame presentation when used with compatible hardware. The working variable-refresh range depends on the selected input, graphics card, driver and game settings.

Connectivity

HDMI and DisplayPort connectivity, with USB-C, USB hub or KVM functions on models that include them. Use a cable rated for the required resolution and refresh rate. USB-C display operation requires DisplayPort Alternate Mode, while charging requires compatible power-delivery support.

Ergonomics and Mounting

The stand and VESA mounting provision vary by model. Ergonomic versions may provide height, tilt, swivel or pivot adjustment, while portable screens use an integrated stand. A monitor arm must support the screen's weight and VESA pattern.
