Well, the problem persist
If I plug the TV, select nview clone mode, Rome total war uses 1024x768.
If I select single display, to use the monitor or TV, Rome total war thinks it has a 2048x768 screen, but in the options it says 1024x768, so I end up seen half of the game.
Another issue, after using the TV, MicroMachines looks like its running on 16-bit.
Too bad that using the TV screew so baddly my PC. As a Nvidia fan boy, I'm really disappointed.
I also tryied uninstalling the 91.31 drivers and installing an older one, not look neither
