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 the appropriate cable supported by your computer or device. Adjust the screen height and tilt to achieve a comfortable viewing angle and position the monitor so the top of the screen is near eye level to reduce neck strain. Use the on-screen display (OSD) controls to set brightness, contrast and colour presets for your environment. If using the built-in speakers, connect the audio output from your device or enable audio over the video connection.
Usage recommendations
For consistent colour-critical work, allow the display to warm up for at least 30 minutes and use calibration tools or software. Keep the monitor firmware and graphics drivers up to date. To reduce power use, select appropriate power-saving settings and lower brightness when possible. When mounting on an arm, ensure the VESA mount supports the monitor weight and that cables are routed to avoid strain.
