I have 2 Macs (which I'll call A and B) and a video-projector. Mac B is connected to the video-projector. I want to show on the video-projector the screen of Mac A but the video-projector is too far to be connected to Mac A. So I was looking for a way to connect Mac A to Mac B (via Wifi or such, no cables) which gives the information to the video-projector. I want anyway that the files to show and all the commands are given to Mac A because nobody will have the access to Mac B.
So the question is the following, if I use Mac B as a screen for Mac A, is Mac B going to give the information to video-projector?
Are there better ways for doing this? Does it work also with the sound?
I hope the question is clear, thanks a lot.
P.s. If anybody has a good solution that works on Windows or Linux I would be happy too.
