Greetings:

I've been attempting to set up two monitors for my business for quite some time now. I can't seem to figure out what I'm doing wrong. I believe I've purchased all of the correct cords, dongles, etc. However when I try to set them up, EPIC fail. CONTROL PANEL -> DISPLAY -> CHANGE DISPLAY SETTINGS. Once I'm in CHANGE DISPLAY SETTINGS, only 1 monitor shows. I've tried to hit detect and get nothing.

I found some info online which stated, "Every graphics card provides at least two outputs, with most motherboards also providing display output and cheap access to a second graphics card."

Here are my questions:

1. How many graphics cards are in the Optiplex 780?

2. Do I need to add a graphics card?

3. If so, how do I add a graphics card?

4. What am I doing WRONG?

Thank you very much for your time and assistance in this matter.
