For some reason almost every existing DisplayPort KVM is junk and this one takes over, I just get an image from the bios and then a black screen, from every port, computer and cable I use have tested. Also, I had a weird keyboard that worked fine in another KVM's dedicated keyboard port. This doesn't work unless I use a USB hub port instead. It's mostly worth its weight in scrap and a bit more.
