Not looked at my xorg.conf for quite some time now so it might well need a
tweak (I've just noticed that xvmc bits are still in, and xvmc is not
supported on my 8500GT!) for performance but it works just fine with my
Samsung series 5 42" at 1920x1080 using the latest Nvidia driver, if it
helps here are the relevant section verbatim:
Section "Monitor"
