I am using an European version this TV and will try to describe problems I have here.

Connected to a Nvidia 7300GT with an DVI to HDMI cable.

I was not able to get the TV setup to 1080p with 50hz, so I choosed 1080p and 60hz. Then afterwards I changed the xorg.conf and changed/added the folowing lines : 

Option         "UseEDIDDpi" "false"
Option         "UseEDID" "true"

Modes       "1920x1080_50"
VertRefresh     49-51

and rebooted. After that I had 50hz.

The line "1920x1080_50" uses the EDID information it gets of the TV and sets things up correctly. In the /var/log/Xorg.0.log you can then see that it chooses the right resolution.

"UseEDIDDpi" "false" is important, otherwise you will get very small unreadable characters.


Alternate solution (I used first).

I was not able to get the TV setup to 1080p with 50hz, so I choosed 1080p and 60hz. Then afterwards I changed the xorg.conf to the right 1080p@50hz Modeline i found in the HDTV list in the MythTV modeline database. 

       # 1920x1080 @ 50 Hz (EDID) HSync: 56.25 kHz
       ModeLine "1920x1080" 148.50 1920 2448 2496 2640 1080 1084 1089 1125 +HSync +VSync

And changed the VertRefresh to : 

       VertRefresh     49-51

and rebooted. After that I had 50hz.

My latest xorg.conf
