There are many occasions where I would like to put simple graphics up on a TV - to use it like a giant oscilloscope, or to log data via an optically isolated link. Monochrome, low resolution would be fine.
It sounds like you have to pay licensing fees if you want to sell a product using HDMI ($5K a year!?). So VGA seems like the simplest approach, and if the TV doesn't have a VGA input, you can buy a VGA to composite converter. (But I have noticed that some newer TV's only seem to accept HDMI as an input option).
I know there are options on the web for building your own VGA interface - and I may end up resorting to that. But I thought I would add my name to those who would like a VGA connector on a DISCO board - as Clive commented back in 2016 :
"I'm surprised ST doesn't have a DISCO with a VGA 15-pin connector on it. A Video DAC might be asking a bit much, but a resistor chain/ladder would do, and it wouldn't have the licensing or IP issues of HDMI, etc."
