Both laptop screen and external monitor go black
I have the new Acer Aspire laptop and a TV which I use as a monitor. They have worked together very happily some time now. But yesterday I had to do a forced shutdown when the start button would not work and the TV screen shrank in size and there were error messages. When I rebooted, the TV monitor stayed black and a computer screen came alive for about 10 seconds as it was rebooting, then went black. I disconnected the TV from the computer and started her up and the computer screen behaved itself.
Even if I set all of the display parameters to indicate only one screen (the computer screen), if the TV monitor is connected to the computer, I end up with two black screens.
I have tried many display duplicate and extension.
No new software installed.
There is one clue. I disconnect the TV monitor from the computer, boot up, choose duplicates to display. Then I connect the TV monitor to the computer. What happens, for about one second, is that both screens light up.
What is going on? Help please.
