Now that you know the things that are required, let’s move on to the step-by-step procedure to set up a MacBook as a second monitor for a PC.

Check Compatibility

First things first, Ensure your MacBook supports Target Display Mode. This feature is available on certain Mac models, typically those released before 2019. To check if your MacBook qualifies, head to Apple’s official support page or check your MacBook’s specifications.

Activate Target Display Mode

With the cables in place, it’s time to activate Target Display Mode on your MacBook. Here’s how:

  • For iMac Models: Turn on your iMac and the MacBook. Connect them using the Thunderbolt or Mini DisplayPort cable. Press and hold the “Command (⌘) + F2” keys on your iMac’s keyboard until the MacBook’s desktop appears on the iMac screen.
  • For MacBook Models: If you’re using a MacBook as your secondary display, simply press “Command (⌘) + F2” on its keyboard to activate Target Display Mode.

Configure Display Settings on Your PC

Once your MacBook is in Target Display Mode, head to your PC and configure the display settings. Go to “Settings > System > Display” and select the newly connected display. You can adjust the orientation, resolution, and other settings to ensure a seamless dual-monitor setup.
