Can HDMI be interfaced into the Propeller

iseries

I see where the Raspberry pie has an interface for HDMI and that some display cards require this interface.

The Propeller is able to generate VGA and has an internal font and VGA code but VGA is a thing of the past.

Is it possible to build an HDMI interface for the Propeller so that it can display debug information on an LCD screen or something?

This gets way over my head, but there is a table on this link that shows the addresses. analog.com/en/analog-dialogue/articles/hdmi-made-easy.html
Maybe something could be worked out with the signal? Could possibly use a VGA to HDMI converter "after the fact" if it's a bench build, between whatever Prop board you use with VGA out and the monitor.

You can adapt from DVI to HDMI with cheap cable...

Sorry, I can't sell these anymore, but I did post the design files to the Prop forum, if you want to make your own...

Actually, I'm thinking about revisiting this now that I see Newhaven sells displays with HDMI interface...

There could also be P2 interest around this too.
What are the current interface chip choices ? Anything newer/better than SSD1963, TFP410 ?

I can find a good price here https://lcsc.com/search?q=SSD1963QL9&filter_field=mpn
and they also show https://lcsc.com/search?q=SSD2828QN4&filter_field=mpn
but I'm not sure where the SSD2828 fits into the various LVDS choices spectrum

I don't recall where I got my SSD1963 chips from at the moment...
I do know that Solomon stuff is hard to source sometimes though...

Is lcsc.com a good place to buy from?

I've not used them yet, but likely will.
They list STC8 and N76E series parts, (very low cost small MCUs) which are on design shortlists here.
