Review on Universal Laptop Docking Station for Windows and Mac - Plugable USB 3.0 Dual DisplayPort 4K Monitor with Gigabit Ethernet, Audio, and 6 USB Ports by Mike Cassidy

So far I am happy with it and it works very well. Note that I originally had an issue with my Dell Nvidia G-Sync monitors - they don't work with DisplayPort connections. It has something to do with G-Sync. I had to buy two DP to HDMI adapters and plug them into the monitors' HDMI ports. Please note that I had to purchase active adapters (Pluggable also sells them) to get 2k resolution over HDMI. If you have passive adapters you only get 1080. I think connecting to the HDMI port saved me $260 on a DisplayPort KVM because I can easily switch the video source on the monitors. Still, I deducted a star for that - other than that initial issue, I had no problems with it. I use it when I work from home.
