Having exhausted every avenue, I'm turning to you guys. I have had a dual monitor setup with my laptop(Inspiron 1545 with GM45 Intel Card) extending to a regular LCD screen. It worked for two months and until recently has stopped working.
I have uninstalled, reinstalled, uninstalled, reinstalled the newest drivers
, changed the cables(power supply and VGA), system restored back a month to when it was working, and changed the power outlet.
This originally worked flawlessly and now the laptop is not recognizing any device I attach via the VGA output. I have plugged the laptop into another monitor with no avail as well. I find it hard to believe that this would stop working one day with no notice or any problems. I have also tried attaching a projector that had worked for over a year with the laptop and have gotten nothing.
I receive a black screen as if to say this something being outputted, but nothing is displayed. Both windows screen resolution and the intel GUI both do not recognize another device.
