Hi guys, I'm not the most technical person in the world so I might need technical terms dimmed down somewhat to understand everything but I'll go ahead and explain my problem.

On the back of my pc I have 2 DVI ports

I use the first one for my monitor and I'm trying to use the 2nd one for my projector however the 2nd port will not display an output to my monitor or the projector so I need to keep going behind my desk and switching the wires which is a bit inconvenient.

I know it's not the monitor or the projector as they both work fine in port #1 but neither will work in port #2, I have updated my graphics card drivers (I think, not sure if I did this properly), and nothing has changed.

I wondered if there was something I was doing wrong or could do differently so that I could dual screen with my monitor and my projector on at the same time

Thanks in advance

btw my graphics card is

AMD HD Radeon 6800

How would I do that? I've tried going into my display but it doesn't detect a second monitor to extend an output to
