    in safe mode does it auto change the resolution? i thought i had to press a series of keys after f8 to change the resolution
  3. What kind of cable(s) are you using to connect your pc to the tv? Most connection methods support ddc/ci, which would allow Windows to automatically detect what resolutions are supported, and change the desktop resolution accordingly. You shouldn't even need safe mode.

    Safe mode will boot without drivers.... effectively making your video card resolution something like 640x480 or something close to it.

    So restart....
    Begin pressing F8 for 10-15 seconds.....
    press the down arrow 1 time
    Hit enter

    That should get you into the OS where you can set your native resolution

    thanks very much! i have never needed to use safe mode before so wish me luck :p. your help is much appreciated
  6. MauveCloud may be on to something.....

    You should at the very least have video on your POST screen(right after your PC restarts) no matter what your OS resolution is. Maybe there is a cable issue.
  7. I had to chuckle when I read the title - definitely not what I was expecting. But I would like to second MauveCloud. Skit75's method will definitely work, however.
