Dear colleagues!

Please, help with your HDMI experience.

I have a project with a plenty of small linux boards which must be connected to the cheap displays. I'd like to use these:

This display works via HDMI with Raspberry but refuse to works with Orange Pi PC plus.  As I can understand it is same issue described there

My only need from linux board : eMMC (or NAND) memory (SD card is not reliable) and cooperation with such displays. Raspberry can work but does not have eMMC chip.

What do u think , can I use A20-Olinuxino-Lime-4GB or another Olinuxino board?

Thanks!
