I have a dual monitor setup running under Windows 7. With my previous operating system Windows XP I could just turn off the primary monitor to concentrate on something which was displayed on the second monitor.
Now, if I do turn off the primary display, the second display also blackens, thus I cannot use the second monitor alone.
The situation I want to use this for, is reading a website or text file for a couple of minutes without being distracted by the stuff shown on the first display. Afterwards, if I need to use the Windows task bar again, I could then turn on the first display again.
I know that I could just move my window from the second monitor to the first one and then turn off the second one instead, and afterwards when I'm finished reading I could move the window again, but that is a lot of hassle.
I want the second monitor to stay on when I turn off the first display.
Is that possible in Windows 7?

I think it depends on you hardware configuration, if your monitor is connected via HDMI, DVI, Display Port or any other digital connector your pc "knows" if a monitor is connected and/or switched off, and so windows trys to set your second monitor as main display, but this seem to fail.
