It works fine for me; however only 4 stars because it doesn't work with some settings. My display is a Monoprice 4K IPS monitor. My late 2013 Macbook Pro connected to the monitor's display port with a mini display worked fine. However; My late 2013 Macbook Pro used a mini-display for the KVM display port and then the display port on the monitor was not working (distortions on the screen and frequent power outages). I later upgraded to a 2018 Macbook Pro and plugged in the USB-C cable from the display port to the KVM display port and then to the monitor's display port and everything works fine. Beautiful 3840X2160@60Hz.
