FAQs About Using iMac as a Monitor

What is Target Display Mode?

Target Display Mode is a feature available on certain iMac models that lets the user use their device as an external monitor for another computer.

What do I do if my Target Display Mode doesn’t Work?

If your Target Display Mode doesn’t work, check if you have done the steps correctly. If it still won’t work, try to restart your iMac, unplug all the cables you connected, and plug it in again. After that, press Command + F2 or Command + Fn + F2 to enable the feature.

Why won't Command + F2 work on my iMac?

Other third-party keyboards won’t enable Target Display Mode by using Command + F2. To fix this concern, open your Keyboard System Preferences and look for "Use all F1, F2, etc. keys as standard function keys" if it is checked. If it is, you can use the other key Command + Fn + F2 to turn on your Target Display Mode.
