Orange Pi 4 LTS HDMI not outputing.

NinjaFB

Hi, this is my first post here so I apologise for any errors.                                                                                                
I recently purchased an Orange PI 4 LTS and when I power it and plug it into a display Android appears and is usable.                                       
When I inserted an SD card with Ubuntu from the Pi 4 LTS website using Balena Etcher the green light flashes regularly but nothing comes up on the display (
no output from cable detected)                                                                                                                              
Help would be much appreciated

I don't know why, I had this issue too, but I somehow resolved it by running an image for the wrong Orange Pi. Then I could boot and I did some stuff, overwriting the SPI flash and then tried with the correct image, which then suddenly worked.
