20 Grant,

22 By default most TVs overscan inputs due to broadcast signals at the
23 edges as the picture there is not well defined and can have white
24 overscan lines and such. The TV compensates by overscanning which
25 basically zooms in on the picture making (on my 46" Samsung TV) the
26 outer 1-1.5" of the picture disappear.
27
28 On my TV it was fairly simple to turn this off, I just had to label the
29 HDMI input as "DVI PC" and it automatically turned off any picture
30 processing/overscanning. Yours may be similar.

32 Sorry if there's typos, I have a bandaged finger and it's a PITA to type
33 with. I think I fixed all of them.
