Im new to Ubuntu, and can't get it to recognise my Sony Bravia TV as a monitor. In the Displays Settings menu, it shows my regular monitor (23" BENQ) as a Laptop which concerns me a little, not sure if this is part of the problem.

I have a GeForce GTX 275 Graphics Card, with my TV plugged in through the HDMI output. It runs fine in my windows environment

Thanks

Do you have three output devices connected or two? Mine ran into problems when I had three, so I disconnected one of them. –  Emre Sep 20 '12 at 6:05

If you have not already done so then install the NVidia graphics driver. Go to System Settings > Additional Drivers to see what is available.

I have 2 options in there and tried both - NVIDEA Accelerated Graphics Drivers (version current) [Recommended] and NVIDIA Accelerated Graphics Driver (post-release updates) (version current-updates). Neither of them displayed anything –  Zyth May 7 '12 at 11:55
    
install the ` NVIDEA Accelerated Graphics Drivers (version current)` or via command line sudo apt-get install nvidia-current be sure to do a reboot afterwards! –  blade19899 Sep 20 '12 at 7:13

I tried to compile CUDA once and the Ubuntu drivers couldn't get it off the water (it can't recognize my DVI output as a separate screen, two screens with different aspect ratio are always tied together)

Not everyone would recommend this, but I found NVidia's proprietary drivers work best for Ubuntu. It can recognize my monitors properly, but you have to install it manually and not via Ubuntu's Additional drivers interface. Follow the instructions here to install this driver (you have to blacklist Ubuntu's open source drivers first), you can skip the CUDA part.

And to be clear, NVidia is to blame for this mess, they hold up a lot of information to open source developers.
