laptop display set to display on tv now cannot use laptop display and tv unavailable
I have done this successfully before. Set up tv as laptop display. Now when the laptop boots up only my background screen appears with blue lines on the side. I thought I picked clone but must have slipped and gotten another choice and now cannot hook up to any tv or monitor to get the display. How can Ichange it back --??from when it is booting up? It is an hp 9000 nvidia REally need this as is also work computer.
this has been resolved. I used an old monitor I had and was able to get it back to laptop. Thanks anyway.
