I set my laptop to make WIDI my primary screen. It didn't work. Now the laptop has only a black screen and any display that I plug in via HDMI or VGA is blue with only a mouse cursor. I can move the mouse and it acts like there is a display to the left of the blue screen, which I assume is the non-existent WIDI display. I have rebooted several times, but it always comes up the same. I have tried the laptop's display mirror/project key, but it does nothing.
I'm working with a Toshiba Satellite P55-A5200B. It came with Windows 8 and I upgraded to Windows 8.1.
Can anyone tell me how to disable the WIDI display g.without being able to see anything?
