Re: Issue with raspberry pi4 and lcd 4k sharp 5.5 inch

It seems that it occurs on 2k and 4k LCD both with pi4(buster OS). I got same problems with alliexpress 4k LCD. It also occurs in 2k LCD in Wanhao D7 with pi4. Maybe we have to wait OS upgrade.

I report this problem in Raspberry pi forum, but no solution yet.

Do you have correct color in 4k lcd with Pi4? somehow the color is not correct with Pi4. Maybe the middle line issue is connected to the weird color problem.

Hello roy_anz,
I'm sorry I'm not helping you! But I have a question, if you can help me I will be grateful! I saw that you use the RPi4 with nano dlp, can you please tell me how you connected the Pi4, direct control or via ramps/Arduino? I use the nanoshield v2.2 with the Pi4, but it's for 2 weeks I can't get it going, it doesn't move the engine (in manual, and via UI), and won't turn on the UV LED! Can you help me? Tell me how you connected everything, and how did you set up nanodlp? Thank you very much!
