IOGear GCS1934 4k/60Hz Displayport 4 port KVM/KVMP with audio

Description

This KVM supports 4 computers with up to 4K resolution. It also supports displayport daisy chaining so you can connect more than one display. Check IOGear website for more details.
It works as designed. Reason for selling is I had to switch over to HDMI due to some problems inherent with Displayport that you should be aware of.
Switching back and forth is more like a hot disconnect/hot plug operation. For instance in Windows it deals with that usually just fine, but in BIOS or another OS, it often results in a black screen which blocks me from doing my work. This isn't an IOGear problem, but a problem with how Displayport works.
Also IOGear still doesn't support modern keyboards and mice. You can still use them but you have to plug them into the hub ports instead of the dedicated keyboard/mouse ports.
The USB/DP cables I am including are probably not what came with it.
