Review on HDMI 4 Port KVM Switch: Share Keyboards, Mice, and Devices Across 4 Computers with 4K@60Hz Support by Ario Rojas

The KVM is small and made out of nice, solid metal, not plastic, which is great. I was able to connect my Blu-ray (4K) player to two external monitors. I wanted to see if switching between both monitors maintains quality and if there are any performance issues. I was not disappointed. I was able to switch from one monitor to another without losing the movie I was viewing. The KVM comes with enough cables to cover all the ports offered. A power cord is included, but you will need a 5V charger. The one your phone uses will do. Another feature I love about this product is the external control module that connects directly to the KVM with a cable and allows you to press a button and toggle between inputs. Great if you want to set this up in a more permanent environment.
