A Guide on How to Use iMac as a Monitor for a Windows PC

iMacs often come with high-resolution Retina displays that offer vibrant colors, sharp images, and wide viewing angles, making them ideal for tasks like photo and video editing, graphic design, gaming, and media consumption. If you have both iMac and Windows computers, it is a good idea to set up your iMac as a second monitor for PC for either work or leisure purposes.

This article will elaborate on how to use iMac as a monitor for PC for you. Read on.

Requirements for your iMac

Unfortunately, not every iMac can be used as an external monitor for a Windows computer. Only certain older iMac models that have a feature called Target Display Mode can be used as an external display when plugged into another computer.

The requirements for different iMac models vary. Check your iMac model and make sure your device meets all requirements below.

• Your iMac is running macOS 10.13 High Sierra or earlier. If your iMac has a newer version of macOS installed, follow this guide to install older versions of macOS on your iMac.
• The cable connecting the iMac and PC computers must be a Thunderbolt or Thunderbolt 2  cable if your iMac model was introduced in 2011, 2012, 2013, and mid-2014, or a Mini DisplayPort cable for an iMac model introduced in 2009 and 2010.

After verifying that the Target Display Mode feature is available on your iMac, you can proceed to use the iMac as a monitor for your PC.
