I'm not sure if this has anything to do with what you're talking about, but
here goes anyway.
I'm using a DVI>>> HDMI cable going into the regular HDMI port on my HDTV
(There is another HDMI port that is intended for "computer" resolutions, IE:
It displays quite nicely, however, the outer edges of the screen aren't
shown (probablt 50-25px worth).. could this be the vertical/horizontal
This is what I'm currently using as my xorg.conf:
By the way, changing between the different settings (like 480p and 1080i),
doesn't seem to have any effect on the appearance... I looked under gnome's
"screen resolution" app, and it stays at 1280x720 ... o_0 It seems as if
linux is ignoring my xorg.conf file!
Any suggestions would be greatly appreciated... and I'm sure it would help
out alot of other people as well...
