How to split a video image into four?
I've been trying to think if there is a way to split a video image into four or more parts (like split-screen) so that each part can be displayed on a separate screen. With this, I was hoping to make a big screen from several smaller LCD monitors which could also be split up for some gaming.
In my head I've figured that the easiest would be to run through a computer or shuttle in which the programme could split an image into separate channels, and then have as many out ports from the shuttle to each of the screens.
Essentially what I'm asking is if anyone has done this before and if so, how please?
