I bought this 4 port kvm to hook up mi xbox mi desktop and mi laptop... since i have 2 port kvm same brand hooked up with my 22 inch monitor, the funny thing is the item is low quility it arrived with little scratch also the image with the 4 port kvm is blurry shadowy.. isnt clear with the 2 port kvm is not perfect but at least is clear and you dont notice also with the laptop it doesnt get all the full resolution... wich is weird because with the other kvm and also hooked up directly with lcd tv i have no problems with the resolution of the laptop... all i can say is buy at your own risk as i did but also im sure like me youll regret the buy... is pure garbage im sure out there is another one that works better...i would only recomend the buy if you are going to hook it up with something that doesnt require alot of resolution or a clean image
