I upgraded my computer to Windows 7 today, and now I can't figure out how to detect my external monitors. I go into the displays and press "detect" but nothing is happening. The monitor just says "no signal." Is there something special I need to do? It used to always work on what I had before (Windows Vista).
Also, no drivers are needed for this monitor. When I first bought this monitor, I didn't have to install anything. I just plugged it in to my Windows Vista and it detected it fine.
In fact, I tried two seperate monitors which I have used with my machine prior to upgrading to windows 7 (neither of them requiring drivers). Still nothing.
I've tried the win+p trick, but nothing popped up when doing that.
I also restarted my computer with both monitors plugged in. Still didn't work.
