Sewell SwitchDeck 4K HDMI KVM Switch, Switch easily between two PCs/Macs/game console

Works for 4k 60fps

First, the cables that are supplied will not support 4k 60fps. I would suggest buying new cables . I use a 1 foot cable for monitor to switch and 3 foot cables to computers. I still get green sparkles on black with changing content. Would not use this for games of movies, but is perfect for my work.
