This is weird.

With a config that asks the Intel driver to ignore VGA and VGA-2, that
specifies using only TMDS-1, with all the logs saying that in deed this
is what it is doing, if I plug an analog VGA cable to the PC and TV, I
get an image on VGA? 

It is 4:3 and all pink/green, but it exists when it should not.
