Invalid Format when laptop connected to HDMI TV
I messed up display settings for when I attach a TV via HDMI to my laptop. I set the system to display only on the TV (OK, not a totally stupid idea) and then picked a resolution the TV doesn't support (that was TOTALLY stupid!) When I disconnect the TV, laptop display works as normal. As soon as I connect the TV, laptop screen blanks and TV goes to Invalid Format. I have tried to change display settings through the control panel with the TV disconnected, but as soon as I plug in the TV, it goes back to the bad resolution on the TV and no laptop display.
Is this stored in the registry somewhere? I want to reset the flag telling the system to display only on 2nd display.
Please help
