Just finished a patch that visualizes sound input using a jit.gl.sketch that is sent to a gl Render window. This identical information is also drawn to a jit.matrix, where different effects are added to it, so the two outputs look significantly different. I want to send the 2 different windows to 2 projectors at the same time. I am using a mac mini, so I do have 2 display ports, but I cannot figure out how to go fullscreen with both the gl and the matrix. Matrox is not an option right now, so any other solution or idea would be very welcome.
Create a jit.window. Set shared 1. Make another window.
Lets say all your outputs are 1024 x 768. Set each window state with the position AND size argument.
Main screen is 1024 x 768. Thus position is 0 x 0 size 1024 x 768
window 1 position is 1025 x 768 , size 1024 x 768
Window 2 position is 2049 x 768, size 1024 x 768
Adapt this according to the output needed for your beamers. Jit.window also allows you to turn off the border.
