Hi all!
I have bought a portable HDMI display hoping it will work together with an Orange pi in one of my custom project I have planned.
The display is this:

As you can see it is originally a MIPI display, but I have bought the converter board that makes it HDMI so I had high hopes. Long story short: it is not working.
I have tested the display on a PC and it work without an issue. It first blinks some led (maybe some handshaking) and the display shows up afterwars. When I plug in the same board into my Orange Pi PC plus, all I get is the led blinking like it would never finish some handshaking.
I am using the legacy kernel because I need GPU acceleration for the project.
I am trying for a longer time as of now, but nothing seems to work so far. The operating system is armbian and I also asked on their forum with no answer yet.
I know that the resolution is pretty high, but I only need the hardware resolution to be high so if the software works for it on a lower resolution that is fine for me too...
Tomorrow I might have a chance to test the same display on a Raspberry pi too (just to have more insight with more devices being tested as I only tested it with PC so far). I would prefer the orange pi however for the project...
Thank you for any ideas in advance

PS.: Some information hinted that I might add custom resolutions with building my own kernel. I use the orange pi in question daily so I skipped this possible solution so far as I have no experience and I feel I would backup my pi and take a long turn for nothing...
