Parts missing plus appears to be incompatible with my system
"The box should have contained a remote port selector and user instructions, but it didn't. Instructions were available on-line, though and there are supposedly hotkey combinations to toggle between ports. However, I could not get this device to work with my system. I had two computers with DP ports, and a monitor with an HDMI port. I had purchased a DP to HDMI adapter cable, which worked with a single computer and the monitor, but not with the KVM switch."
