Windows 7: Laptop/ Video Card Won't Recognize Second Monitor

24 Aug 2011   #11

Windows 7 64-Bit Home Premium

Is there any way to test the port via software? I think it's the port that's gone. My friend has the exact same Inspiron 1545 and looking at the updates, they're all the same. Tested with the same wire, monitor, and driver for the Mobile 4, it works with his. Anything?

It would seem your tests have condemed your port. I know of no software to test a port, but you may take it to a shop. Maybe they can measure output from it.
