I am having difficulty getting the game to run on my new TV. I am running the Nvidia GTX260 and I cant seem to find a working resolution to allow the game to run. any suggestions? 
Welcome to the land of Bravia. see signature
I have not set mine up in awhile so I'm gonna be sketchy.
The TV HDMI port you use is important. Stay off the port set up for mobile devices.
I use HDMI 2. TV settings, you should have options here. Which type of wide yada yada. Also theres a option called game mode.......... so you might need some adjustments here?????
I had been using GTX 260's in SLI, it worked fine. Used the pc connect on an older Bravia, use HDMI current Bravia both worked. You might need to use an older driver. I was using game ready ver 330.????? Anything after only benefited newer hardware.
Select only native resolution! If you loaded a current issued driver, DSR could be messing with you. Make sure game video res is native res. U should be able to handle high res textures in game?????????????????
Earlier posts pretty much covered it, I just chimed in cuz I use a Bravia, it will work for you once adjusted.
Also something I ran into.
I changed my vid card, I changed it using the HDMI port on my Bravia. Now on reboot with new card in place, certain things are registered/recognized whatever. What happened is I lost the analog sound ports on my mobo, windows blanks them because its been decided that you are gonna use and need digital only, and that digital is provided by the video card. I discovered that I needed to install that vid card with an analog monitor, then switch over after the fact.
Your 260 has a 2 wire cable that plugs mobo directly to vid card, if you want HDMI audio from that card........................
