Simply cant get display to work
So this is the first time I have tried anything with a Raspberry Pi (4B) - I have a WaveShare 7.9 inch screen attached (resolution is 400x1289).
Ive loaded followed all the steps, but when the Rasberry Pi boots, the screen shows a load of white lines (the resolution is clearly completely out of sync).
I have tried editing the config.txt to include hdmi_cvt 400 1280 60 6 0 0 0
Nothing works. please help
Hey,
I have the same type of screen just a bit bigger, this is how i solved the same problem on mine:
hdmi_cvt 400 1280 60
hdmi_group=2
hdmi_mode=87give it a try? :)
thank you :) so I tried this config with a standard Pi OS install, and it shows an image.
but - the quality is HORRIBLE :(
Maybe try flipping the 2 around, looks like the rotation messes stuff up?
hdmi_cvt 1280 400 60
hdmi_group=2
hdmi_mode=87Hey @Newtothis,
This weekend I also got one of these screens and already have an open thread regarding settings here:

Maybe they help you as well.
