I bought this to use the same 4K monitor and keyboard between my personal and work computers. That serves the purpose well. And I have confirmed that it supports 4K@60Hz. One negative point I noticed: since I connected the laptop to this device, the screen now and then goes black for a few seconds. I've noticed the same thing with another monitor that won't connect to this unit, but I'm not sure if it's a cable issue. The clicking just started when I got this device.
