changing the resolution, I would imagine the TV "auto-compensates" (by
stretching) for that just like a PC monitor does.

I used http://www.gossamer-threads.com/lists/mythtv/users/324685#324685 as
a hint how to underscan. I never bevor done it and I have not the faintest
idea how underscan works. Google isn't really a help.

Isn't it right that I have to lower the H and V timings to shrink the
screen size so that it fits in?

That might help me but what should I do with this?
My TV isn't in it so do I have to test all lines to see if one fits?

> One thing that strikes me as odd is that the issue even exists with
HDMI. What's the point in overscan when you don't have a DA converter?

Don't ask me, I have no idea of all that.
All I knew is that the fglrx driver got it right just from the beginning.
