Connecting new laptop to older projector


Aug 7, 2017
I have a new Dell Inspiron 5000 running Win10 and I'm trying to connect with an older Dell 3200MP projector. I am physically connecting with the cable that came with the projector which has both VGA and USB connectors for the laptop. I am using the USB as the computer does not have a VGA connector. When I plug in the projector the computer dings as if recognizing it but the projector does not find a signal. I did lower the resolution on the laptop to 1024 by 768, the native resolution of the projector.
What is the solution to this connection issue? Dell support was no help at all.
