Whether normal or HDMI with 3D the KVM switch does what he is and what you expect from him more I need to prop. Not write. A negative point there nonetheless. - The 2 connecting cables to the 2 PCs are unfortunately (in my case) a little too short but that the assessment is no deduction.
What in other recessions is that the switch between 5 to 10 seconds required until it switches over, I can not confirm. For me it switches like my predecessor (LevelOne 2-Port USB Cable KVM with Audio) within a maximum of 3 seconds.
5 * and a recommendation my part, of course there are.
