Can I Use My 24-inch iMac as a Monitor? Target Display Requirements

Wondering, is your 24-inch iMac can be used as an external monitor? Unfortunately, you cannot use 24-inch iMac 4.5K Retina Display as an external monitor or target monitor. This is because the Mac before 2014, have official support to add the Target Display/External Monitor, and from 2014 or later Mac, Apple lift this support. However, with time, Apple has added much more improvements which makes it easy to share and use other displays and tablets as External Monitor with Apple devices.

In addition, there is no confirmation or news from Apple to let us use 24-inch iMac as a Monitor. However, if you have an alternate display, then it can be used as an external monitor with up to 6K Resolution Monitor. There are plenty of External Displays available that works with iMac, Mac Mini, and many other computers, without any compatibility issues.

Though, the newer macOS and iPadOS update added an amazing feature that lets you screen share the Mac and iPad screen with each other, which is known by the name SideCar. Make sure to update the Mac and iPad to the latest version and refer to our detailed article on What is SideCar: Compatible Mac and How to Use SideCar.
