Output different sources of video to 3 projectors from a single laptop/computer
We recently got 2 extra projectors fitted to our assembly hall. In total we now have 3 all connected to a single laptop displaying the same content. Is it possible to project 3 different videos to the projectors from a single laptop/desktop. We basically want to have powerpoints running on the side projectors and have video on the middle.
There is a possiblilty of using raspberry pi and hooking it up to the network and have vnc on it. This would allow the computer to remote into it.
But is there a another way.
Thanks in advance for your help.
