Just tried driving the panel directly via DVI-D using the same
ATSC-1080i modeline I have been using fine under analogue connection,
and ..........

It works. 100% picture is definitely clearer now all I need is a gefen
DVI switcher. cos I can't be doing with unpluging cables every couple
of hours.

Thanks for the idea. Altough EDID data was useless from the panel
itself the result is good.

Tried a progressive version of the same modeline and its a no-go the
image is stuck at the bottom of the screen and repeats itself 2.5
times. still I've made progress.
