List of video devices via terminal

Question

How do you specify computer video devices through the terminal? Is there a team that lists them?

Answer 1

To display the video output of devices (e.g. monitors),

$ system_profiler SPDisplaysDataType

To display video input devices (such as webcams),

$ system_profiler SPCameraDataType

To get only device names, filter the list accordingly:

$ system_profiler SPCameraDataType | grep "^    [^ ]" | sed "s/    //" | sed "s/://"

Answer 2

system_profiler

Answer 3

system_profiler SPDisplaysDataType

or

ioreg | grep -i display

Note that the system_profiler command is case sensitive.
