Just thought I'd chime in another view to this common problem. I see quite a few people claiming that the EDID is not being read/seen properly when infact it is. It is very common for TV manufactures (all of them) to delibrately provide incorrect Horz + Vert refresh rates to PC's. Why? because the average user that connects a PC wants the best possible picture which is generally Native Resolution @ 60hz on LCDs.
Most EDID's on Tv's contain all the possible Resolutions and HZ you could ever want without the hastle of modelines. Its actually nvidia-settings in Xorg that is delibrately ommiting modes outside of the reported Frequencies.

This can be overidden simply in the device section of xorg.conf with

Option "UseEDIDFreqs" "FALSE"

If you look though the /var/log/Xorg.0.log you will see modes that have been rejected.

Simply extend your Horz and Vert refresh rates in Monito section to include rejected.

HorizSync 15.7 - 68.0
VertRefresh 24.0 - 75.0


What I also do is is ignore unwanted modes that normally are not associated with movie playback. In the device section of xorg.conf add

Option "ModeValidation" "NoDFPNativeResolutionCheck,AllowNon60HzDFPModes,NoXServerModes,NoVesaModes"

The usual lines in Sceen section are also required
Option "DynamicTwinView" "False"
Option "FlatPanelProperties" "Scaling = Native"

If by chance you have a HD Ready TV (Not full HD) with a max res of 1360X768, You will also need to add to Screen Section so it includes 1080P

SubSection "Display"
Depth 24
Modes "1920x1080"
EndSubSection


I've tried and tested this method on many different TV's and brands successully

For some poeple starting out on a fresh install, a useful way to generate a good base xorg.conf for Nvidia is using

# nvidia-xconfig --force-generate --no-logo --no-twinview --no-composite --depth=24 --no-dynamic-twinview --no-flip --exact-mode-timings-dvi
