[mythtv-users] how to set up xorg.conf for overscan

[Eyal Lebedinsky]

Jay,

So you say that selling a unit saying it is 1280x720 which cannot (there is no
way to adjust this to) display the whole 1280x720 (for any of the inputs - it
trims my DVD player component input and set-top tuner component input) is just
fine?

In this case there is no point for a discussion, it becomes a matter of opinion.
I paid for 1280x720 and got about 1180x680, I am annoyed and you are not.

cheers
