I have a mid 2014 15" MacBook Pro Retina connected to 3 1920x1080 monitors on thunderbolt+HMDI ports (NVIDIA GeForce GT 750M 2048 MB). The monitors are in portrait mode with total screen resolution of 3240x1920.
I would like to be able to make an application run in full screen across all three monitors using the full screen mode introduced in Yosemite. At present, I can scale a window to almost fit the full screen manually. Is it possible to make this happen with the green full screen button in the gui?
