Waveshare 4" 800x480 HDMI display not working

[Clive]

Hi.

I have an Orange PI Zero 2

It displays fine on a normal TV through HDMI but on the waveshare there is no display at all.

The waveshare display works fine on the HDMI output of my Windows PC.

I have chased my tail for 2 weeks looking for a solution but can't get it to work.

If you can please point me in the right direction I would really appreciate it.

I connected the HDMI display, booted and ran the diagnostics...

Wishing you all the best and thanks.

Hi,

besides the fact that you are using a different board take note that you are using either a user-built or unofficial image which issues may not receive any attention.

Hi Werner,

 

I'll try the offical image first.

Thanks a lot.
