Can I Use My MacBook as a Monitor?

Yes, you can use your MacBook as a monitor, but it's important to understand the limitations: MacBooks don't have HDMI input ports, meaning you can't simply plug in a cable like a traditional monitor.

Here's what actually works in 2026:

• Can you connect a Mac to a monitor? Yes - MacBooks can OUTPUT to external monitors
• Can I use my Mac as a monitor? Yes - through AirPlay, third-party apps, or capture devices
• How to connect Mac to PC monitor? Use USB-C to HDMI/DisplayPort cables for output

The key difference: Your MacBook can BE a monitor (with workarounds), but cannot accept direct video input like traditional displays.

Why Use Your MacBook as a Second Monitor?

• Gaming on bigger screens: Play Nintendo Switch, PS5, or Xbox on your MacBook display
• Extend your workspace: Use an old MacBook as a second screen for productivity
• Can you hook up a MacBook to a monitor? Absolutely - both as input source AND display
• Portable dual-screen setup: Perfect for travel or remote work without carrying extra monitors

Method 2: How to Use MacBook as a Monitor for Another Mac with AirPlay (Wireless)

Here are the steps to use your Macbook as a secondary monitor with AirPlay:

1. Make sure both your Macbook and the primary Mac you want to use as the external display are on the same Wi-Fi network and signed into the same Apple ID account.
2. On the primary Mac, go to System Preferences > Displays.
3. Click "Add Display" and select your Macbook from the list of available AirPlay displays.
4. By default, it will mirror your primary Mac's screen. To use the Macbook as an extended display instead, click "Display Settings".
5. Select the AirPlay screen and under "Use As", choose "Stop Mirroring".
6. Now select "Use as: Extended Display" to use the Macbook as a secondary extended monitor.
7. For the best display quality, change the resolution to "Scaled" and select a lower resolution like 1920 x 1080.
8. Arrange the displays to match the physical setup on your desk by dragging the display representations.

That's it! Your Macbook will now function as an extended wireless secondary monitor for the primary Mac. Keep in mind this feature requires a 2018 or later Macbook Pro/Air, 2019 or later iMac/Mac Pro, iMac Pro, or 2020 Mac mini running macOS Monterey or later. You can find more information on this method by referring to the guide available on Apple's official website.

Advantages:

• Simple and cost-effective
• No additional hardware required

Disadvantages:

• Limited to Apple devices
• Wireless connection can affect clarity and stability

Common AirPlay Issues & Fixes:

Problem: "AirPlay device not showing up"

• Solution: Ensure both devices are on the same Wi-Fi network (not guest networks)
• Go to System Preferences → Firewall → Uncheck "Block all incoming connections"

Problem: "Laggy or choppy performance"

• Solution: Close bandwidth-heavy apps (iCloud sync, backups)
• Use 5GHz Wi-Fi instead of 2.4GHz for better speed

Problem: "Can't extend display, only mirroring works"

• Solution: Update both devices to macOS Ventura (13.0) or later
• Restart both devices and try again

AirPlay vs. Traditional Monitor Connection:

Many users ask "can you connect a Mac to a monitor?" - yes, but AirPlay offers wireless freedom. For wired connections to external monitors, use USB-C to HDMI cables instead.

Some troubleshooting tips:

• Restart both Macs
• Unplug and reconnect the cable
• Use the keyboard that came with the iMac, as some third-party keyboards don't support Target Display Mode

However, it's important to note that Target Display Mode only works with certain older iMac models and is not supported on newer Macs according to Apple. If your iMac is from 2015 or later, you'll need to use alternative solutions like Luna Display, Duet Display, or Sidecar to use it as an external monitor.

Method 3: How to Connect Mac to PC Monitor Using Third-Party Software

You can use third-party software or apps to turn your Macbook into a secondary monitor. There are many options available, such as SpaceDesk, Duet Display, and AirDisplay. Below are the proven steps for installing and setting up the software to make it work effectively.

Step by step guide on using Spacedesk to turn your Macbook as a secondary monitor

Spacedesk is a software that enables a device to function as an external monitor. It has received a lot of attention and recommendations on platforms like YouTube and Reddit. It offers both wired and wireless modes, but the wireless mode is considered to be more stable. The best part is, it is completely free of charge. However, some users have reported issues with uninstalling files.

Here are the steps to use Spacedesk to turn your Macbook into a secondary monitor for your Windows PC:

1. Download and install the Spacedesk Driver software on your Windows PC from the Spacedesk website. Make sure to allow the firewall exception during installation.

3. To optimize the display, go to Windows Settings > System > Display on your PC. Select the Spacedesk display, then adjust the resolution and scaling to your preference.
4. Configure the monitor layout in Windows Settings > System > Display to match the physical positioning of your screens. This allows you to move your mouse seamlessly between them.
5. In the Spacedesk Viewer app on your Macbook, click the gear icon and select Settings for additional options like resolution and quality.

Some key points:

2. Make sure to log into Duet with the same account on both computers and sign up for Duet Air or Duet Pro.
3. On your Macbook, click the Desktop tab in Duet and select Mirror or Extend once you see your primary computer.
4. If both computers are on macOS 12.3 or later, you can also connect them using an official Apple Thunderbolt cable. The instructions are the same, but you'll need to ensure they recognize each other over the Thunderbolt bridge.
5. Once connected, simply move your cursor to the edge of your primary display and it will automatically appear on your Macbook. You can then drag windows and applications between the displays.

Using Duet Display allows you to use your Macbook as a wireless or wired second monitor, increasing your productivity by providing extra screen real estate. Duet's proprietary technology ensures low latency and efficient use of system resources.
