" ... I verified this by plugging in a StarTech MST hub behind the KVM. ... All of the pieces work fine on their own (Monitors, graphics card, MST hub, KVM), just not together at the same time. ... For all other use cases (one monitor shared between multiple computers) this would work fine. ... "
" ... I have a StarTech 2 port DP KVM, but now I have more computers and it was time for an upgrade. ... Not many other companies even make a 4 port DP KVM, and most that do want an outrageous price. ... "
" ... Very good KVM. ... "
" ... Plugged it in, and it worked. ... I bought the 2-port Mini DisplayPort to use with a Surface tablet, Apple Mac Pro, Apple 27" display, Apple USB keyboard, USB wireless mouse and USB headset. ... "
" ... Setup was simple: no power cord required, and it comes with two DisplayPort+USB cable combos. ... And since the cables provided with the unit have the USB+DP cables connected together, I opted to provide my own USB cable also. ... Summary: if your computer/docking station don't have standard-sized DP connectors, you'll need to provide your own DP cable, and a USB Type-A to Type-B cable. ... And you need a DP-to-monitor cable also. ... "
" ... Does high resolutions, audio, and mini display port so I can hook my my mac via the lightning port. ... Great to have a high-end windows PC and a mac connected to the same KVM with minimal fuss. ... "
" ... Bought these for some employees at work that needed a KVM switch. ... They have UHD monitors so it took the right cables. ... "
" ... - Works great for two DisplayPort computers with a single DisplayPort 1920x1200 monitor ... - Included were two sets of cables that were basically a DisplayPort and USB cable glued together ... "

" ... The other issue is apparently when it switches from one desktop to the next it doesn't keep the device its plugged into on. ... When switching back to my windows desktop it takes about 3~4 seconds and about a third of the time it'll be in time to keep my monitor from going to sleep. ... "
