ListDisplays
Takes a type-0x6 output buffer containing the array of #DisplayInfo output entries. Returns an output u64.
OpenDisplay
Takes a #DisplayName as input. Returns an output u64, the Display-handle.
To open the default display, input string "Default" can be used.
OpenDefaultDisplay
Returns an output u64.
Probably not (?) used by newer official user-processes, since those use OpenDisplay with the default string instead.
CloseDisplay
Takes an input u64 Display-handle.
