The HAT doesn't work right with the Pi 0. You have to use the cable.

They know about the problem and say they may fix it in the future.

Are you connecting VCC to 3.3V? Connecting it to 5V is what makes it crash.

I've recently received the 7.5 inch display, tried it with Raspberry Pi 4/zero, I can't get it even to work. I noticed that my display doesn't look the same as everybody's else's, I think I received a different display.... Screen image

That's the 880x528 black/white/red panel. Have you tried epd_7in5b_HD_test.py?

Yes, it worked also I had the interface wrongly attached. Thank you @missionfloyd
