Windows 7: Display Problems: Switched from default display to non-usable.

Windows 7
Display Problems: Switched from default display to non-usable.

Hello guys! I really need someones help. I my video card is nvidia geforce gt 520mx
So this is what happened:
Right Click on background > Screen Resolution. I accidentally switched the display that shows everything that happens in the monitor to the one that does not.

Here is a picture I made using my other computer:

I pressed "Detect" and after it showed 2 more blanked displays.
In the "Display" there was something like "Only show display 1" (which is a default display) and "Only show Display 2" which is the display from geforce 520.

I wanted to get rid of the other displays, but accidentally pressed on "Only show display 2"
So now my laptop does not display anything, it became blank.

When I restart laptop and click on "Start Windows Normally" it shows Windows starting and then everything becomes blank.
When I restart laptop using "Safe Mode", the computer starts but I cannot change the display to the default one, it shows totally different display.
Here is a picture I made in safe mode:

What can I do to solve this? I tried to do "System Restore" in safe mode but it shows some weird window

Please help.
