For the display port, it's just heavily used and worn. Too loose to stay connected reliably. This was a $120 used computer with windows 10 and a 2T HDD, so I can't complain if I have to stick to the VGA for now.Now that you mention the HDD, holy cripes it's loud. Like LOUD. I've been around desktop PCs since the early 90's and this is the winner in the category of annoying. I can actually hear it in the other room. I was going to set this up as a network storage type deal, but I'm going to rethink my plans.
