I need to split my footage across three screens, One screen will be the master and the other two will slave to the master using brightsign units. How can I split the picture/ footage into 3 parts so that each screen has a third of the picture/ footage? Can theis be done in premiere pro or is there a better application for this? Thank you all in advance.
Matrox makes units called "TripleHead2Go" and they come with different connection options. Basically, they take a graphics output from the PC or Mac display card which has a standard height, but triple width dimensions, and the hardware in the box splits that 1 ultra-wide graphics output into 3 discreet outputs of standard sizing across 3 displays.
I don't know if that would fit your particular need without knowing more details about the involved hardware, software and workflow though. But something to look into.

Exporting at the correct resolution should do the trick. For example, three 1920 x 1080 monitors would require 5760 x 1080 to fill all three screens.
