Just in case this thread turns up in a future search.  The useEdidDpi false
is not supposed to be ignored.  FWIW I dont think it is ignoring it. I
think the nvidia driver is just choosing to use the display size from the
edid to calculate the dpi instead of using what I specified in the
xorg.conf file. Telling it to ignore all edid seems to fix the dpi issue,
but if I do that I don't know how to set the display resolution. Ive tried
adding modlines but did not succeed.

I've decided its not worth more time foolong with it. The tv probably won't
last much longer anyway.

Thanks,

Jeremy
