I have a 60" Pioneer Kuro 1080p display connected via HDMI from the HDMI-out
on an Asus board (geforce 8200 on-board video card).  To avoid any confusion
with an Onkyo AVR that sits in the middle of all this, I pulled the EDID
from the Pioneer panel and pointed my xorg.conf at that file.  The xorg log
confirms that a Pioneer display is connected (without this EDID file, xorg
always reported the Onkyo AVR as the connected device).

Anyway, my panel detects "1080p" when I monitor the Mythtv input.

I have obvious overscan, and wonder what my best option is to fix that.
Should I upgrade to the 185.18.14 nvidia driver? (I noticed atrpms has that
version now)  I have 177.80 now.  Figured this couldn;t hurt.
