The display color is abnormal.
• Does the display appear discolored (16 colors)?

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
