“DP cable doesn't connect to my computer I'm not very computer knowledgeable, so bear with me. One of the cables that comes with this monitor, I think it's the DP cable, cannot be connected to my computer because there isn't a port that it fits into. But the 3 other cables that came with this monitor (DVI, VGA, and USB) all connect properly, and my monitor is working. My question is, do I need to have the DP cable connected to get a better picture on my monitor? If so, Is there a separate piece I need to buy to connect the DP cable to my computer?”
