Configuring Projection Params

Get some Text Editor and open /home/<youruser>/projection-config.json

Every time you save the file the plugin will reload configs.

display[].monitor_bounds: This field is used to identify the monitor (in other words, positioning the opengl window into the system space). If you change a monitor resolution or position on the operating system config, you should update this field so it matches the new configs

display[].projection_enabled: If a projection window should be displayed in this monitor.

display[].virtual_screen: This is like a mapping of a render area and a monitor area.
    You can also create blends (useful when projecting to one larger screen composed by multiple projectors)
    Black level adjusts (useful when projecting to one larger screen composed by multiple projectors)
    Help lines (useful for aligning one or multiple projectors)
    White Balance
