get display name from NSScreen

NSScreen+DeviceName.swift

extension CGDirectDisplayID {

This solution not worked in M1 machine, any update for M1

which step is failed and return nil (#40, #46, #51, or #59)? Currently, I can't find an M1 machine around me, so I can't debug this issue.

#8, kernResult is return 0

This is my solution, it also works for M1:
