Does anyone know if its possible to disable the internal display when the 520c is connected to an external display. The only options i have are extended or screen mirroring. I am running system 7.5.5. If it is not possible to disable the internal screen does anyone know what the computer does if you disconnect the internal screen and plug in an external display. Does it automatically use the external display like on most pc laptops or does it expect the internal screen to always be there and working.
