Review on TRENDnet 2-Port 4K DisplayPort 1.2 KVM Switch: Ultra High-Definition Video, Audio, USB 2.0, Integrated Cables (Black) by William Turner

I've had several of these units from different manufacturers and they were both good and weird. This one is no different. This works very well most of the time, but sometimes when I change monitors the screen gets really small and I have to turn the monitor off and on again to get it to the right size. This is a minor annoyance in a product that otherwise performs very well and does what few other KVMs can - 2560-1440 resolution with DVI.
