Multiple Monitor Ports? Help please
When it comes to computers, I really don't understand much. I have about the same knowledge as an average computer user, so I would like some help on this issue. Basically, on the back on my computer, there are two ports to plug in the monitor cable. For some reason, my primary one (separated from others) isn't working. When I plug in the cable, I don't get a signal from the computer. However, if I plug the monitor cable into the other port, which seems like a secondary port, it works fine. Can anyone clear up the difference between the two ports? And why my primary one isn't working? I would like to go back to using the regular one instead of this new one. Is something wrong the computer? Like videocards etc? Any help would be appreciated.
