This morning , I hit the Project to Second Screen only button. I didn't set up the 2nd screen to receive a connection. There was no 2nd screen to project to. When this happened, the dell screen went blank or black. It looked like the device turned off. I can't get the tablet out of the black screen mode or turn it on or off. How do I fix this problem?
I did the same thing yesterday. I was having so many other problems that I can't remember how I fixed it, but I did get my screen back. All that comes to mind is maybe I held the power button down for a count of 10, or until something happened.
