I have 2 monitors, and I was trying to switch my display from both of them to just the one on the right so I could play my 360 on the other like I do all the time, but I accidentally chose some 3rd monitor that doesn't exist so now both monitors are blank. I tried booting up in safe mode and vga mode trying to switch it, but that part of the control panel doesn't open in those modes. I am completely lost and not sure what to do. Any tips would be greatly appreciated.
