I don't know why, but this connection resulted in very noticeable lines on my screen - a smaller version of the lines you see when recording a computer screen, but are still very clear. It made me a little sick so I had to send it back. I've never connected it to my other laptop, so I can't comment on how well the dual connection works. I can say that pressing the switch button turned it off on my current laptop, so it's likely it would switch to another without issue.
