I setup on a RPi 3B
and it works fine. (no screen)
I put a waveshare27inch onto the RPi and set the display to the “waveshare27inch” and it displays!
Great. But anytime there is an update to the screen, the waveshare screen blinks fullscreen black, fullscreen white, white lettering on black, then black lettering on white screen.
This does this for all screen updates.
I tried changing refresh rates, FPS, fastAndFuruious and other settings for the screen. Nothing seems to work and the screen keeps blinking.
Anyone have any ideas ?
ALSO, when you shut the power off on the RPi, the 2.7inch display stays on the screen. I disconnected the hat from the RPi and it stays on the screen. Anyone have any ideas on how to clear this upon power down?
