I've had this KVM for 2 years now and have very few complaints. I have 4 computers connected to it (3 PCs running Windows 10, Linux Ubuntu 18.04) and a Mac. There are many things I like about this device and overall I have very few complaints. You'll need to plan on buying your own cables for this as they don't come with them and make sure you use good quality DisplayPort cables. I connected it to 2 Dell U2417H monitors and they are stable and not blurry. I found another reviewer who mentioned that sometimes one of the monitors doesn't return immediately when the computer goes to sleep. I've found that if I turn this monitor off and then back on, the problem goes away on its own. Actually the problem is only if I leave it overnight. Devices connected to the USB hub work as expected. I used to use an old PS2 keyboard with the USB adapter attached, but for some reason I lost my keyboard, so I switched to a modern USB keyboard and everything is fine. The Mac was a little tricky since the Mac originally only supported one monitor. I was able to get around this by getting a docking station with two Displayport out connectors to connect to KVM. Overall it made my setup easier anyway, now I only have one cable to connect. I would say if you want to use it and minimize problems I would recommend a quality docking station for your device to connect it to KVM. It will make your life easier, keep the clutter to a minimum and really tidy up your workspace. In all my setups, I use my laptop's own monitor as the third display for two external monitors, one of which is set as the main monitor.
