I'm having difficulty getting a signal on my TV even though my VGA cable is properly connected from my laptop to my TV. Where do I need to go in Vista so that I can sync the two up?
There will be a key conbination to change the signal so it is mirrored on your tv, look at the FN and the keys associated with it. It will tell you in the manual.
Your screen will have to be set at a resolution and frequency that your tv can accept to display the screen properley. Without knowing your laptop and tv model no more help is available.
