I have a problem with my raspberry pi zero. My HDMI screen shows weird things (see below). Other screens work fine it is only this one. I can move my mouse fine. Can I solve this issue or do I have to send it back? I appreciate your help.
EDIT: I have tried using different sources and HDMI cables.I tried rotating the output of the pi and set the signal strenght up in the config.txt file. I unplugged and plugged the ribbon cable on the back of the screen.
