How to use

Adjust display settings such as brightness, input selection and colour presets using the on-screen menu to match your working conditions.

Recommendations

For best results in colour-critical work, allow the monitor to warm up for 20–30 minutes, use a calibrated colour profile when possible and set ambient lighting to avoid strong reflections. When mounting, ensure the VESA arm supports the monitor weight and follow the manufacturer’s installation instructions.
