Not sure what you are asking. Are you trying to have multiple clients using difference resolutions and window modes? If so you can use the “Screen” class to change the resolution and window mode. Screen.SetResolution(int x, int y) and Screen.fullScreen = true/false
I see. It should be possible to do this but I need some more information. What is the desired functionality? Is is 4 applications running on the same pc with the settings ( window mode, resolution ), or 1 application split across the 4 displays?
