Sudden loss of picture on one of the displays
I've got no idea what to think of it, why it happened and because of what. I have 2 displays, had them for 2 years now and Nvidia GTX 9700. One of them is connected to my graphic card via HDMI and the other one is plugged via DP. A few minutes ago, while I was talking to my friend on Facebook, suddenly my screens went blank and after a second both of my screens were linked via Nvidia Surround - thought that it's strange as I didn't ask for it and didn't give this command. But ok, went to Nvidia control panel and unchecked option "span displays with surround". Applied and from this moment my 2 screens stopped working. The one connected via HDMI. First of all - whaaaaaaaaaaat????
What's going on in a first place that system changes display properties without any action on my part.And second - why now my second display stopped working?
I know that it's not the cable cause when I unplug HDMI, then the 2 monitor starts working. In Nvidia Control Panel I can change settings in only one monitor(one connected via HDMI), in Windows settings I do see 2 displays but the one that was working just a minute ago, is greyed out and I can only change settings of one. What's going on here?
Edit: Forgot to mention. Did system restart, it didn't help. In device manager I can see 2 monitors, there is nothing wrong with them.
