You probably also need to export the EDID data from within the NVIDIA
Settings GUI. Save it the edid.bin to your home directory e.g.
~/.nVidia-edid/edid.bin. Then add the following to your xorg.conf -

Option         "CustomEDID" "DFP-0:/home/mythtv/.nVidia-edid/edid.bin"

If you can you should use the NVIDIA macros to set the resolution (again
in your xorg.conf) -

SubSection     "Display"

        #          1080p           720p            480p
        Depth       24
        Modes      "1920x1080_60" "1280x720_60" "720x480_60"
EndSubSection
