How to fix my tv screen?

How can I fix this problem with my TV screen resolution?

• Basically, I got a new TV to use as a monitor, and when I try to put the computer in full resolution, it puts the left half of the screen on the RIGHT and theres a red line down the screen, about a third from the right. In the Nvidia control panel, it seems to think that the native resolution is 1440x900 and if I set it to that, it works (albiet being in a horrible resolution). An interesting thing I'd like to point out also - I got it working once, full resolution with the screen all in the right place. I accidentally pushed auto adjust on the screen and it went back to its retarded half screen state. It's a LOGIK screen. Does anyone know how i can fix this? (also, sorry, no idea how i got it working before. i was unpluggin and repluggin stuff in and out, restarted it and for some reason it worked.)

• Answer:

  check if there is any resolution option in your tv.
