[QUOTE = "davieboy, post: 33156, member: 10157"] change kodi GUI to 720p for the Pi4, that's really the only thing you need to do after the install to prevent the black screens. Take it you can get to the configuration page ok and everything else is setup in there - GPIO pin etc etc? [/ QUOTE] After setting the GUI to be limited to 720p, I can see the OSD fine, no blanking. However, Hyperion is started (latest Alpha 9 release) but nothing on LEDs. I am using GPIO18 for data and GND to GND on WS2812b, but nothing is coming out. You say: configuration page...which is the config page? How do I get to it?
