Note: The AirPlay Mirroring menu extra icon is blue when AirPlay Mirroring is on.
You can choose between two desktop resolution matching modes that let you select which display will have the best image. When AirPlay Mirroring is turned on, select a "Match Desktop Size" choice via the AirPlay Mirroring menu extra.
Match Desktop Size To: Apple TV
AirPlay Mirroring changes the desktop resolution to best match your Apple TV, resulting in 16:9 aspect ratio that fills the HDTV screen. This setting often produces the sharpest image on the HDTV.
Match Desktop Size To: This Mac
AirPlay Mirroring scales the contents of the desktop to fit on the Apple TV, leaving the resolution of your Mac's display unchanged. Use this setting for the sharpest image on your Mac's display.
