[simon chmiewliski] "is it possible to create on big comp and render out the 4 display areas as 4 single 1920 x 1080 (for example) videos?"
Yes. Create one single working comp that's the full size of all your displays (with space for bezels).
Then create four render comps at 1920x1080. Drop your working comp into each of these render comps and re-position it as necessary.
You'll continue to work in your working comp, but when it comes time for output, add all four render comps to the render queue and go. There's no need to render the working comp.
