Replaced "Display" environment settings
The Mac external display has two main display modes.One is the "extended desktop" mode (hereinafter, expanded desktop) that uses the main desktop screen.Especially if you are a notebook type MacBook Air or MacBook PRO users, the desktop screen should be more comfortable.
The other is the "mirroring" mode (hereinafter, mirroring) that displays the same screen as the main display on external displays, projectors, large high -definition TVs, etc.Used when displaying a Mac screen on another screen when presentation.
The display mode of these external displays is set from the "Display" panel in the system environment settings, but this "display" panel has evolved significantly in Monterey.
When the external display was connected, the setting window was displayed for each display before MacOS Big Sur, whereas Monterey could set multiple displays on one screen.
In addition, a keyboard and mouse image are displayed on the screen, making it easy to imagine an actual screen layout when an external display is connected to a Mac.
