Review on 🖥️ StarTech.com 4 Port DisplayPort KVM Switch w/ Audio - USB - Keyboard, Video, Mouse, Computer Switch Box for 2560x1600 DP Monitor (SV431DPUA) - Black by John Arsov

This is the second KVM I've tried, the first was Kanex SnapX and it wasn't overly reliable. Kanex sometimes gave noise on the picture and disconnected. I was very happy to see the full picture without any interruptions from this thing. The keyboard macros are amazing too, I can press ctrl+ctrl+1 to connect to port 1 and so on, which is great because I can keep the KVM out of sight and never have to press the buttons on its front panel. So far I've used this with a Mac Mini, a PC with a GTX970 graphics card, a PS4 (requires a special active HDMI to DisplayPort converter) and will likely add a virtual desktop thin client on the latter port later.
