My Windows 8 laptop (Dell Vostro 1520) was working OK up until now with the laptop monitor and a ASUS monitor connected via a VGA port. Tonight I pulled the monitor out of while the OS was still running to test another PC and when I plugged the monitor in the VGA port again its not being recognized by my laptop.
My laptop can now only recognize one monitor, namely the external monitor. If I disconnect the monitor it can recognize the laptop monitor, but it shows up as "Other" in the control panel display window. When I connect the ASUS monitor it is the only monitor recognized and I am unable to set my old resolution. The display looks ugly. So I'm no longer able to use dual monitors and what ever works, works with poor resolution.
How can I trouble shoot this?
