How to use

Place the monitor on a stable surface or attach it to a VESA-compatible arm or bracket. Connect the video source using a suitable cable (e.g., DisplayPort or HDMI) and plug in the power cord. Use the on-screen display (OSD) menu to select input, adjust brightness, contrast and colour settings to match your environment. Adjust the stand for comfortable viewing height, tilt and angle; pivot to portrait mode when needed. For audio, connect external devices to the headphone jack or use the built-in speakers for everyday calls and media.

Recommendations

For prolonged use, enable the blue light reducer and set monitor brightness to a comfortable level to reduce eye strain. Calibrate colour settings if accurate colour reproduction is required for photo or video work. When creating a multi-monitor setup, align bezels and match display settings across screens for consistent appearance. Ensure adequate ventilation around the monitor and use VESA mounting if desk space is limited.
