I bought a Orange PI 4G-IOT but as we know HDMI is working weird. But I was able to connect one monitor to it.
Then I bought a LCD, but it that didn't work (there was a white screen when turned on). The seller on Aliexpress prompted to update the firmware, that I did, and the LCD worked. But now has stopped working HDMI! Absolutely! (I tried Android 6 and 8).
Prompt where to take a old firmware with the working 48Hz HDMI?

If you manually set the resolution sometimes and its not a good one for the screen, it wont show at all.

I had HDMI working on one of the monitors. I just changed the firmware to the one that is posted in Downloads. It doesn't work after that. Previously, monitors wrote that "format is not supported", now simply "no signal".

Yes, I use the 5.5inch display. But for some projects I also need HDMI. And such firmware where LCD and HDMI work at the same time I did not meet.

Prompt the modern monitor working with HDMI? I tried IIYAMA GE2288HS, on the website AMD in the list of monitors with FreeSync this model declared work from 47 Hz. But it did not work, maybe need something else to work FreeSync.

It's not a configuration issue. The  bridge driver(LT8912b) is not completed at all. It's just a bunch off useless letters after each other nothing more. I have a driver for it , but nowdays i don't have the time to implement it in the kernel.It's only works with 3.18. The 4.4 not supported by this Mediatek chip. I tried to complie once I think and the kernel is missing a tons of files. If anyone have the patient and time. Feel free to download and use it.
