How to use

Place the monitor on a stable desk surface and connect it to your computer using a compatible video cable. Adjust the display resolution in your operating system to 3440 x 1440 for optimal sharpness. Position the screen at eye level and at an appropriate viewing distance to reduce eye strain. Use the on-screen menu to calibrate brightness, contrast and colour settings according to ambient lighting and your task-specific needs. For multi-window workflows, arrange applications side-by-side or use the operating system's window management features to take full advantage of the 21:9 workspace.

Recommendations

For colour-critical tasks, perform a hardware calibration with a colourimeter and review results in a controlled lighting environment. When gaming, enable the monitor's recommended display mode and adjust frame rate settings on your GPU to match the monitor's capabilities. To prolong panel life, avoid leaving static high-contrast images on-screen for prolonged periods and reduce brightness when working in low-light conditions.
