Welcome to AAC!

I have not looked at the requirements of HDMI.
Do you really need HDMI?
I can do VGA output from STM32.

Firstly Thanks!

Well yes, I need to know if they have HDMI output cause in that case I should use an IC or sth else to get HDMI output. I didnt find anything in datasheet about that but I wanna be sure.

With analog video, there were chips that could overlay text for closed-captioning, channel display, caller ID, time and such. IIRC they were pretty easy to interface to a microcontroller, according to an article in some magazine like Circuit Cellar Ink or Radio-Electronics. Doing that sort of thing to HDMI seems to be much more difficult and requires FPGAs and things with molecular structures.
