mavericks vs yosemite vs el capitan vs sierra

It should be noted that the fact that the “Detect Monitors” button is not visible in OS X Mavericks does not indicate a problem or error, and does not really indicate an output device problem, it is simply hidden from everyday use presumably because most of the time Mac usually doesn’t have problems finding and connecting external monitors. Of course, you want to make sure the physical connection is protected by an external monitor, and if you have problems, check the cables for the LCD monitor, projector, or television.

Click “Recognize Screens” while holding down the Option button to use the feature as intendedĪt this point, the external monitor should be found and operated as usual by launching the secondary “Monitors” window for that monitor.

Hold down the “Option” key to display the “Detect Screens” button – note that it replaces the “Collect Windows” button.

Go to the  Apple menu and choose System Preferences.

Use the external display recognition screens on OS X Macsįollow these steps when the secondary monitor detects that it’s already connected to your Mac:

If you are having trouble displaying either the feature or the external display correctly, you need to do this. This applies to all types of secondary monitors, be it an external monitor, AirPlay mirroring, AirDisplay, a projector, an HDMI connection to a TV, or any other additional monitor you’ve tried to connect to your Mac. This does not indicate a problem on the Mac or external monitor you want to use, all you have to do is change the Option key to display the detection feature and then be able to perform the detection as usual. Like some other features in the newer versions of OS X, the “Detect Screens” button is now hidden by default and no longer appears immediately in the Display Settings of OS X El Capitan, OS X Yosemite, and OS X Mavericks.
