Many Windows users wonder if they can use their iMac as an external monitor. You might have a beautiful iMac display sitting there and want to put it to good use with your Windows PC. The truth is, using an iMac as a monitor for Windows is possible, but it’s not as simple as just plugging in a cable.
Target Display Mode, Apple’s old solution, doesn’t work with Windows PCs. However, modern solutions like Luna Display make it possible to use your iMac as a monitor for Windows. This guide will show you exactly what works, what doesn’t, and how to set it up step by step.
Key Takeaways
- Target Display Mode only works on older iMacs (mid-2014 or earlier) and doesn’t support Windows PCs
- Luna Display is the best modern solution for using iMac as monitor for Windows PC
- Ethernet connection is recommended for PC-to-iMac setup for best performance
- Not ideal for gaming or video editing due to potential pixelation during fast motion
- Works with iMacs from 2011 to newer models, including 5K displays

What is Target Display Mode and Why It Doesn’t Work with Windows?
Target Display Mode was a feature Apple introduced in 2009 that allowed certain iMacs to work as external monitors. You could press Command-F2 on the iMac keyboard, and it would switch to showing the display from another connected Mac. However, this feature has significant limitations that prevent it from working with Windows PCs.
Target Display Mode only works on iMac models from mid-2014 or earlier. These older iMacs need to be running macOS High Sierra or earlier to support this feature. Even if you have one of these older iMacs, imac target display mode windows compatibility simply doesn’t exist. Apple designed Target Display Mode to work only between Mac computers, not with Windows PCs or any other operating systems.
The reason Target Display Mode doesn’t work with Windows comes down to hardware and software limitations. The feature requires specific Thunderbolt or Mini DisplayPort connections that only Mac computers can communicate through properly. When you try to connect a Windows PC to an iMac using Target Display Mode, nothing happens because the iMac doesn’t recognize the Windows computer as a valid input source.
Apple discontinued Target Display Mode starting with iMacs released in late 2014. Newer iMacs simply don’t have the necessary hardware to accept video input from other devices, making it impossible to use them as monitors through any built-in Apple feature.
If you’re having monitor connection issues, it might be related to cable problems rather than Target Display Mode limitations.
Can You Really Use an iMac as a Monitor for Windows 10?
Yes, you can use an iMac as a monitor for Windows 10, but not through Apple’s Target Display Mode. The imac monitor for windows 10 setup requires third-party solutions that work around Apple’s limitations. Many users get confused by outdated guides that suggest Target Display Mode works with Windows, but this information is incorrect.
The most reliable way to use imac as monitor windows is through Luna Display, a hardware and software solution designed specifically for this purpose. Luna Display works by creating a virtual display connection between your Windows PC and iMac over your network or direct cable connection.
For Windows 10 users, the setup process involves:
- Purchasing a Luna Display dongle
- Installing the Luna Display software on your Windows PC
- Installing the Luna Secondary software on your iMac
- Connecting both devices through Ethernet for best performance
This solution works with most iMac models from 2011 onward, including newer 5K iMacs that can’t use Target Display Mode at all. The connection quality is generally good for office work, web browsing, and basic tasks, though it’s not recommended for gaming or video editing.
If you’re experiencing no sound from your monitor after setting up your iMac as a display, you may need to adjust audio settings on your Windows PC.

Why can’t I get my iMac to work as a monitor for my Windows PC?
If you’re having trouble getting your iMac to work as a monitor for your Windows PC, there are several possible reasons.

Can I use any Windows computer with older 2009/2010 iMacs?
Yes, you can use certain older 2009/2010 iMacs as monitors with Windows computers, but only with specific models and adapters.
