Are you holding onto an old iMac, wondering if it’s still useful? Maybe you’ve upgraded to a newer model or switched to a different brand, but you’re not ready to let go of your trusty 2015 iMac just yet. The good news is that you can breathe new life into it by repurposing it as a monitor. But before you do, let’s dive into the details to ensure it’s the right decision for your needs.
The Benefits of Repurposing Your 2015 iMac as a Monitor
Using your old iMac as a monitor can be a cost-effective and eco-friendly solution. Here are some advantages to consider:
Reducing Electronic Waste: By giving your iMac a new purpose, you’re extending its lifespan and reducing the likelihood of it ending up in a landfill. This is a great way to minimize your environmental footprint and contribute to a more sustainable future.
Cost-Effective: Buying a new monitor can be expensive, especially if you’re looking for a high-quality one with similar features to your iMac. Repurposing your old iMac eliminates the need for a new purchase, saving you money that you can allocate elsewhere.
Convenient: If you’re already familiar with the iMac’s interface and settings, using it as a monitor means you won’t need to learn new controls or adjust to a different display. This can be especially beneficial if you’re planning to use it as a secondary monitor for tasks like video editing, coding, or gaming.
Check Your iMac’s Compatibility
Before you start using your 2015 iMac as a monitor, ensure it’s compatible with your current setup. Here are a few things to consider:
Operating System
Your iMac’s operating system will play a significant role in determining its viability as a monitor. If your iMac is running macOS High Sierra (10.13) or later, you can use it as a monitor. However, if it’s running an older version of macOS, you might encounter compatibility issues.
Graphics Card and Resolution
The graphics card and resolution of your iMac will also impact its performance as a monitor. The 2015 iMac models come with either an AMD Radeon R9 M390 or R9 M395X graphics card, which are capable of supporting resolutions up to 5K (5120 x 2880 pixels). If you’re planning to use your iMac as a 5K monitor, ensure that your computer or device can output a 5K signal.
Ports and Connectivity
Take stock of your iMac’s ports and connectivity options:
- Thunderbolt 2 ports: These can be used to connect your iMac to a Mac or PC using a Thunderbolt 3 to Thunderbolt 2 adapter.
- HDMI port: You can connect your iMac to a device using an HDMI cable.
- USB ports: If you have a USB-C device, you’ll need a USB-C to USB adapter to connect it to your iMac.

- Connect your iMac to a power source and turn it on.
- Press the Command + F2 keys on your iMac’s keyboard to enable Target Display Mode.
- You’ll see a prompt on your iMac’s screen indicating that it’s now in Target Display Mode.
Connect Your Devices
Once you’ve enabled Target Display Mode, connect your devices to your iMac. You can use a Thunderbolt 2 cable, HDMI cable, or USB-C to USB adapter, depending on your device’s connectivity options.
Configure Your Display Settings
On your main computer or device, go to the display settings and select your iMac as the external display. You may need to adjust the resolution, brightness, and other settings to your liking.
Common Issues and Troubleshooting
As with any technology, you might encounter some issues when using your 2015 iMac as a monitor. Here are some common problems and their solutions:
Resolution Issues
If you’re experiencing resolution issues, ensure that your iMac is set to the correct resolution. You can do this by going to System Preferences > Displays on your iMac and selecting the desired resolution.
Audio Issues
If you’re not getting audio output from your iMac, check that the audio settings are configured correctly. Make sure that the audio output is set to the iMac’s internal speakers or an external audio device.
Conclusion
Breathing new life into your 2015 iMac as a monitor is a great way to reduce electronic waste, save money, and enjoy a convenient solution for your display needs. By following the guidelines outlined above, you can set up your iMac as a monitor and enjoy a seamless experience.

Can I really use my 2015 iMac as a monitor?
You can use your 2015 iMac as a monitor, but there are some limitations and considerations to keep in mind. The 2015 iMac can still function as a display, but it might not be as straightforward as you’d hope. You’ll need to ensure that the device you’re connecting to the iMac has the correct ports and compatibility.
Before you start, check that your 2015 iMac is running macOS High Sierra or later, as this is necessary for Target Display Mode to work. Additionally, the device you’re connecting to the iMac needs to have a compatible video output, such as Thunderbolt 3 or HDMI. If your devices meet these requirements, you can use your 2015 iMac as a monitor.
What is Target Display Mode, and how does it work?
Target Display Mode is a feature introduced by Apple in 2009 that allows you to use your iMac as an external display for another device. When activated, your iMac’s display becomes an extension of the connected device, allowing you to mirror the screen or use it as a separate display. To enter Target Display Mode, press the Command + F2 keys on your keyboard while your iMac is turned on.
Keep in mind that not all iMacs support Target Display Mode, and the 2015 model is one of the last ones to offer this feature. If you’re using a newer iMac, you might not be able to use Target Display Mode. Also, the connected device needs to be compatible with Target Display Mode, which might not be the case for all devices.
What kind of ports do I need on my devices to use my 2015 iMac as a monitor?
To use your 2015 iMac as a monitor, you’ll need to ensure that the device you’re connecting to has a compatible video output port. The 2015 iMac has a Thunderbolt 2 port, which can be adapted to Thunderbolt 3 using an adapter. The device you’re connecting to the iMac needs to have a Thunderbolt 3 port or an HDMI port.
If your device only has a USB-C port, you might need an adapter or a dongle to convert the signal to Thunderbolt 3 or HDMI. Additionally, if your device is a PC, it might require specific drivers or software to recognize the iMac as an external display.
Can I use my 2015 iMac as a monitor for gaming?
Using your 2015 iMac as a monitor for gaming is possible, but you might not get the best gaming experience. The 2015 iMac’s display is not designed for gaming, and it might not be able to handle high frame rates or fast-paced graphics. Additionally, the iMac’s display panel might not be as responsive as a modern gaming monitor.
That being said, if you still want to use your 2015 iMac as a gaming monitor, you can try adjusting the graphics settings on your gaming device to optimize performance. You might need to reduce the resolution, turn off some graphical effects, or adjust the refresh rate to achieve a smoother gaming experience.
Can I use my 2015 iMac as a monitor for a PC?
Yes, you can use your 2015 iMac as a monitor for a PC, but you’ll need to ensure that the PC has a compatible video output port. You’ll also need to install the necessary drivers or software on the PC to recognize the iMac as an external display.
Keep in mind that using a Mac as a monitor for a PC can be a bit more complicated than using it with another Mac. You might need to use third-party software or drivers to get everything working smoothly.
Will using my 2015 iMac as a monitor affect its performance?
Using your 2015 iMac as a monitor might slightly affect its performance, especially if you’re using it as an extension of another device. The iMac will need to process the video signal and display it on its screen, which can take up some system resources.
However, the performance impact should be minimal, and you might not notice any significant differences. If you’re concerned about performance, you can try closing any unnecessary apps or background processes on the iMac to free up system resources.
Can I use multiple devices with my 2015 iMac as a monitor?
You can use multiple devices with your 2015 iMac as a monitor, but it might require some extra hardware or software. If you want to switch between multiple devices, you might need a KVM switch or a video switcher that can handle multiple input sources.
Alternatively, you can use software solutions that allow you to extend your desktop across multiple devices. However, this might require some setup and configuration to get everything working smoothly.
