Interesting idea. Basic DVI is somewhat VGA with analog signal replaced with TDMS. I think if you limit yourself to only few predefined colors with 8b10b encodi

Interesting idea. Basic DVI is somewhat VGA with analog signal replaced with TDMS. I think if you limit yourself to only few predefined colors with 8b10b encoding hardwired in shift registers, it's doable. (for signal integrity you can only pick colors that have balanced encoding) edit: as pointed in other comment, lowest bit clock is 250MHz, which might be a problem, it seems fastest discrete logic chips are topping out at ~150MHz
