[mythtv-users] nVidia DVI out?

[Steve Frank]

Can you post your modeline?  When I use HDTV timings I get
ghosting--it's like one of the interlaced frames is down several pixels.
It's not unlike Wang Chung's "Everybody Have Fun" video. :-)

------Update------

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.
