1. Let's rule out the problem of the monitor and replace it with another monitor or TV to see if the display is normal.

2. If the display is normal, it indicates that the display is a problem.

3. If the display is abnormal, please use the HDMI cable provided by us, and check whether the HDMI cable is plugged into place

4. Check whether the display is switched to HDMI display (VGA, HDMI, DP switching signal source is HDMI);
