    Have you tried F8 while it is plugged in to the TV?

    Is Dell Quickset installed? I would install Dell quickset and play around with FN F8like JTO said.

    It's possible that vga won't work on your TV and the computer is sending the signal out the VGA port but the TV can't display it.

    Do you have a monitor you can try this on?

    Should be "Fn" + "F8"
