How to use
Place the monitor on a stable desk surface and adjust the height to align the top third of the screen with eye level for comfortable viewing. Connect to your device using a compatible video interface supported by your graphics card to achieve 3840 x 2160 resolution; ensure cable and source settings are configured for 4K output. Use the on-screen display menu to set brightness, contrast and color settings according to your ambient lighting and visual preferences. For best results with photo or video work, allow the display to warm up for a few minutes and use calibrated color profiles when available.
Usage recommendations
For prolonged use, enable ergonomic desk setup practices: maintain an appropriate viewing distance (typically 50–70 cm for a 27" screen), adjust height and tilt to reduce glare, and take regular breaks to minimise eye strain. When working on color-sensitive tasks, use an external hardware or software calibration tool and ensure the source device outputs native 4K resolution and appropriate color depth.
