The display color is abnormal.
• Does the display appear discolored (16 colors)?
- Set the color to 24 bit (true color) or higher. In Windows, go to Control Panel > Display > Settings > Color Quality. (The settings may differ depending on the operating system (OS) you use.)
• Does the display color appear unstable or monochrome?
- Check if the signal cable is connected properly. Reconnect the cable or reinsert the PC's graphics card.
• Are there spots on the screen?
- When using the monitor, pixilated spots (red, green, blue, white, or black) may appear on the screen. This is normal for an LCD screen. It is not an error, nor is it related to the monitor's performance.
No sound from the headphone port.
• Are images displayed using DisplayPort or HDMI input without sound?
- Make sure that the headphone port connections are made properly.
- Try increasing the volume with the joystick.
- Set the audio output of the PC to the monitor you are using. On Microsoft Windows, go to Control Panel > Hardware and Sound > Sound > set the Monitor as default device. (The settings may differ depending on the
operating system (OS) you use.)
