Step-by-Step Guide to Turn Your iMac as a Monitor

Transforming your iMac into a secondary monitor is a valuable way to maximize your workspace. Follow these step-by-step instructions to seamlessly set up your iMac as a monitor:

Connect the Cable or HDMI Adapter

To begin the process of how to use iMac as monitor for PC, you'll need either a Mini DisplayPort cable or an appropriate HDMI adapter. Identify the "input" port on the computer or device you wish to use with the iMac. Depending on the version of your iMac and the device you want to connect, you may need either a Mini DisplayPort to Mini DisplayPort cable, a Mini DisplayPort to HDMI adapter cable, or a USB-C to HDMI adapter. Once you have the correct cable, connect it to the 'input' port of your source device and the other end to the Thunderbolt (or appropriate) port on your iMac.

Enable Target Display Mode

After you have successfully connected your devices, you will need to enable Target Display Mode on your iMac. To do this, press “Command” + “F2” on your iMac's keyboard. This should switch your iMac into Target Display Mode, meaning your iMac will now serve as a display for your other device. If the screen does not immediately switch over, ensure that both devices are powered on and double-check your cable connections to make sure they are secure.

Adjust Display Settings

Finally, to ensure optimal viewing, you may need to adjust the display settings. Using the computer or device now connected to your iMac, navigate to its display settings. The exact location of these settings varies depending on the device & its operating system, but generally, you would go to 'System Preferences' on a Mac and 'Display Settings' on a Windows computer. You should set the resolution to match the resolution of your iMac screen or select the highest resolution available. Adjust also the other parameters such as brightness, contrast, and orientation to your liking. Your iMac is now operating as a secondary monitor.

Tips and Considerations

  1. iMac Compatibility:Keep in mind that only iMac models released between 2009 and 2014 support Target Display Mode. iMacs with Thunderbolt ports (2011-2014) only support Target Display Mode with other Thunderbolt-enabled devices. 
  1. Choose the Right Cable and Adapter: Make sure you select the appropriate cable and adapter according to your device's port and your iMac model (Mini DisplayPort or Thunderbolt). 
  1. Video/Audio Output: While iMacs with Mini DisplayPort or Thunderbolt 1/2 can transmit both video and audio, some adapters may only support video transmission. Verify your adapter's specifications for accurate information. 
  1. Keyboard Functionality:Target Display Mode may also be activated using an external keyboard by pressing the appropriate function key (F2 or display key, depending on the keyboard). 
  1. Exit Target Display Mode: To exit Target Display Mode, press Command + F2 again, or turn off the connected device. 
  1. Performance:Using an iMac as an external display might not provide optimal performance (e.g., input lag) compared with dedicated monitors. Consider this when using the iMac in this capacity, especially for gaming or other latency-sensitive tasks.
