Review on IOGEAR 4-Port 4K DisplayPort KVMP Switch with HDMI and DisplayPort Output USB 3.0 and RS-232, Including Full Set of Cables (TAA Compliant) GCS1934M by Marcelo Apriando

I use this switch with my 27" Dell 4K HDR monitor and four computers: 2 desktops, 1 laptop and 1 Mac Mini. Set it up but it's been working fine ever since It's nice to be able to use standard cables and run USB3 anywhere. Once you get used to 3840 x 2160 HDR @ 60Hz it's very hard to go back. A few notes for potential owners: - Use high quality video cables! DisplayPort seems to be pretty picky about cables and connectors, use a cable that doesn't match your setup and the image may flicker or the monitor may not sync to your computer, the cables that come with the Switch are fine for short runs , but if you need to do more, I've had luck with the Accell DisplayPort 1.2 cable with latches - I'm using a programmie Portable gaming mouse with additional buttons. I had to enable the Switch's "Mouse Passthru Mode" to force my computer to recognize additional features. Configure many aspects of the switch with different keyboard shortcuts - be sure to read the documentation carefully. - There was an error configuring the switch, so I flashed the device's firmware. You can do this if you encounter any problems - it's easy by following the instructions on the IOGear website. Since then he has become rock hard.
