Как подключить мак как второй монитор к windows

Многие пользователи задаются вопросом: можно ли использовать iMac как внешний монитор? Ответ зависит от модели компьютера и используемой операционной системы. Некоторые старые iMac поддерживают режим Target Display Mode, позволяющий использовать их в качестве дисплея для других устройств, но современные модели уже лишены этой функции. В этой статье мы разберём, какие iMac можно использовать как монитор, как подключить их к Mac и Windows, а также какие существуют альтернативные способы.


Какие модели iMac можно использовать как монитор?

Режим Target Display Mode – что это и как работает

Target Display Mode (TDM) – это специальный режим, позволяющий использовать iMac как монитор при подключении к другому Mac через Thunderbolt 2 или Mini DisplayPort. Однако он поддерживается только на моделях iMac с 2009 по 2014 год.

Какие модели iMac поддерживают TDM

  • iMac 27″ (Late 2009 – Mid 2014)
  • iMac 21,5″ (Mid 2011 – Mid 2013)

Почему современные iMac (2015 и новее) не поддерживают TDM

Apple отказалась от этого режима из-за технических и маркетинговых причин:

  • Новые iMac с Retina-дисплеями (5K и 4K) требуют мощного видеосигнала, который невозможно передать через Thunderbolt 2.
  • В iMac 2015+ изменена архитектура дисплея, которая не позволяет ему работать как внешний монитор.

Совместимость iMac с macOS и Windows

Подключение iMac как второго монитора возможно только с macOS, если модель поддерживает Target Display Mode. Windows не поддерживает прямое подключение iMac как монитора, но есть обходные пути с использованием стороннего программного обеспечения.


Как подключить iMac как монитор для MacBook или Mac mini

Подключение через Target Display Mode (iMac 2009–2014)

Если у вас iMac, поддерживающий TDM, выполните следующие шаги:

  1. Подключите iMac к другому Mac с помощью Mini DisplayPort или Thunderbolt 2 (в зависимости от модели).
  2. Включите iMac и войдите в macOS.
  3. Нажмите Cmd + F2 (или Cmd + Fn + F2) на клавиатуре iMac, чтобы активировать режим Target Display Mode.
  4. Теперь iMac должен работать как внешний монитор.

Важно:

  • Не работает с Thunderbolt 3/USB-C без адаптера.
  • TDM недоступен на macOS Monterey и новее.

Использование iMac как монитора для новых Mac (2015 и новее)

Если ваш iMac 2015 года или новее, подключить его как монитор напрямую невозможно. Однако есть альтернативные способы через сторонние приложения.

Программы для использования iMac как монитора:

  • Luna Display – аппаратное решение с USB-C или HDMI-адаптером.
  • Duet Display – подключение через кабель или Wi-Fi.
  • Astropad – для художников и дизайнеров.

Минусы:

  • Не поддерживает 4K и 5K разрешение на полной мощности.
  • Возможны задержки при беспроводном соединении.

Можно ли использовать iMac как монитор для Windows?

Прямое подключение – возможно ли это?

Подключить iMac к Windows через HDMI или DisplayPort невозможно, так как iMac не поддерживает видеовход – он работает только на вывод изображения.

Обходные пути – использование стороннего программного обеспечения

Можно использовать специальные программы, передающие изображение по сети:

Популярные решения:

  • Luna Display (адаптер для Windows)
  • Duet Display (через USB или Wi-Fi)
  • Deskreen (бесплатное приложение для трансляции экрана по Wi-Fi)

Недостатки:

  • Возможны задержки и снижение качества изображения.
  • Невозможно передавать 4K-картинку без проводного соединения.

Как использовать iMac как второй монитор по сети

Подключение через Sidecar (для iPad, аналогично с iMac)

Apple разработала Sidecar – функцию, позволяющую использовать iPad как второй монитор. Однако этот метод не работает для iMac, но похожие решения существуют.

Использование AirPlay для дублирования экрана

  • Если ваш Mac поддерживает AirPlay, можно транслировать экран на iMac (некоторые модели 2017+ поддерживают AirPlay-приёмник).
  • Работает только для macOS Monterey и новее.

Приложения для передачи изображения по Wi-Fi

Если нужно использовать старый iMac как внешний монитор по сети, можно попробовать следующие приложения:

  • Luna Display – передаёт картинку по сети или через USB-адаптер.
  • Duet Display – подключение через Wi-Fi или USB.
  • Deskreen – бесплатное ПО для дублирования экрана на любое устройство.

Старый iMac как монитор – стоит ли использовать?

Какие модели iMac устарели и не подходят для работы как монитор?

  • iMac 2008 года и старше – не поддерживают TDM.
  • iMac 2015 года и новее – не поддерживают видеовход.

Альтернативные способы использования старого iMac

Если ваш iMac не подходит в качестве монитора, его можно использовать иначе:

  • Установить Windows или Linux – превратить в рабочую станцию.
  • Использовать как медиаплеер для просмотра фильмов.
  • Превратить в домашний сервер для хранения файлов.

Заключение – стоит ли использовать iMac как монитор?

Какие iMac можно использовать как монитор?

  • iMac 2009–2014 – поддерживают Target Display Mode.
  • iMac 2017+ с AirPlay – можно использовать для беспроводного дублирования экрана.

Какие iMac не подходят?

  • iMac 2015 года и новее – не поддерживают Target Display Mode.
  • iMac 2008 и старше – устаревшие модели без поддержки внешнего подключения.

Лучшие альтернативные способы

  • Для Mac → Luna Display, Duet Display, AirPlay.
  • Для Windows → Luna Display для Windows, Deskreen.
  • Другие варианты → Установить другую ОС, использовать как медиаплеер.

Вывод: если у вас iMac 2009–2014 годов, его можно легко использовать как монитор. Если модель новее, придётся использовать сторонние программы или найти альтернативное применение.

The rivalry between MacBooks and PCs may forever rage on, but that doesn’t mean the two computers can’t still work together! Using your MacBook as a second display for your PC is a great way to mirror or extend your desktop space. This wikiHow article will teach you the easiest ways to use a MacBook as a second monitor for your Windows PC.

What to Know About Using Your MacBook as a PC Monitor

  • The simplest option is to use a free app like spacedesk to transmit your PC’s screen into a browser window on your MacBook.
  • For better results, you may need to use additional hardware, such as a video capture card, a virtual display adapter, or a specialized dongle (such as Luna Display).
  • You can also use paid third-party apps to easily cast from your PC to your Mac.
  1. Step 1 Install the spacedesk driver on your PC.

    Spacedesk is a screen mirroring or casting app that you can use to extend or mirror your PC’s screen to almost any device. To use it with a MacBook, you’ll need to install the main spacedesk app on your PC and use the browser-based HTML5 viewer on your Mac. Download the driver for Windows 11, 10, or 8.1 here. Open the installation file and follow the prompts.

    • Before installing the driver on your PC, check out the system requirements.
    • Spacedesk’s basic non-commercial private license is free.
  2. Step 2 Verify your setup and installation.

    Once you install spacedesk, you’ll need to take a few more steps to make sure it’s properly set up and ready to go:[1]

    • Go to Control Panel > Programs > Programs and Features and make sure the spacedesk driver is listed.
    • Check if you can see the spacedesk System Tray icon at the bottom right side of the screen. If so, click on it to open the console. Go to the Control tab and make sure the radio button next to ON is selected.
    • Open your PC’s Control Panel and navigate to Windows Firewall > Allow an app through Windows Firewall > Change settings. Select Allow another app, then browse for spacedeskService.exe. Check the box next to its name, as well as the boxes next to Private and Public. Click OK.

  3. Step 3 Make sure your PC and Mac are connected to the same network.

    For spacedesk to work properly, both devices need to be on the same local network (such as a Wi-Fi network or a wired Ethernet network). Before you proceed, check your network settings and connections on both machines.

  4. Step 4 Navigate to http://viewer.spacedesk.net/...

    Navigate to http://viewer.spacedesk.net/ on your Mac. There’s no spacedesk viewer app for macOS, but you can use the browser-based viewer on any device. To get started, visit the viewer website in any browser.

    • Your browser will need to be up to date for this to work. Check for and install any available updates.
  5. Step 5 Select your PC and click Connect.

    If spacedesk is set up correctly, it should automatically detect your PC. Select your PC from the list of available devices and click Connect.

    • If you’re not sure which device is the right one, check your PC’s IP address. Select the device with the matching address in the viewer.
    • Once you connect, the viewer should enter full screen mode and display your PC’s screen on your MacBook.
  6. Step 6 Adjust your settings from your PC’s Display Control Panel.

    On your PC, right-click the Desktop and click Display settings in the context menu. This will open your Display Control Panel. From there, you can choose whether to:[2]

    • Duplicate (mirror) or extend your PC’s display
    • Select which monitor is your primary display
    • Make adjustments to things like the orientation of the display, the size of text and apps on the screen, your screen resolution, and so on.

  1. Step 1 Download and install Deskreen on your PC.

    Deskreen is an open-source application that allows you to turn any computer into a second screen via Wi-Fi. You can download Deskreen from https://deskreen.com.

    • While Deskreen is a free app, the disadvantage is that you need to buy additional hardware to get the best results.
    • You only need to install Deskreen on your PC, as your MacBook can project your PC’s screen via an IP address that Deskreen will give you.
  2. Step 2 Find a virtual display adapter.

    Software like Deskreen relies on the use of a small dongle called a virtual display adapter, usually with an HDMI connector.[3]
    These adapters make your computer think an external display is connected. They tend to be very affordable and will make your second-screen experience much smoother.

    • You may sometimes see virtual display adapters referred to as display dummy plugs.
  3. Step 3 Plug the virtual display adapter into your PC's HDMI port.

    This adapter will come in handy later when we want to trick Deskreen into thinking an external display is connected.

  4. Step 4 Open Deskreen on your PC.

    The homepage for Deskreen will show you a QR code as well as a customized IP address. If you are trying to extend to an iPad or iPhone, the QR code may come in handy. You’ll need the IP address to connect to a MacBook.[4]

    • Before continuing any further, ensure your MacBook and PC are on the same Wi-Fi network.
  5. Step 5 Type the IP address into your Mac's browser.

    Enter the address exactly as you see it on Deskreen, then click Enter.

  6. Step 6 Click Allow on Deskreen from your PC.

    If you entered the IP address correctly, Deskreen should receive notification from your MacBook that it is trying to connect. Allow your MacBook to connect and choose to share your Entire Screen.

    • If you only need to project a single application to your second monitor, you can do so at this time and get to work with your dual monitors!
  7. Step 7 Choose your second screen from Deskreen's list of options.

    Once you cast your entire screen, Deskreen should show you two screens: your current desktop as it appears to you, and a blank version of it. This blank version is the extension enabled by your virtual display adapter. Click on it to project it onto your MacBook. You will now see your PC’s screen in the browser window on your Mac.

    • When you’ve chosen the view you want, click Confirm in the Deskreen app window.
  8. Step 8 Change your PC's projection settings to Extend.

    With the virtual display adapter plugged in, hold down the Windows and P keys simultaneously, then choose Extend from the options that appear in the ensuing menu.[5]

    • Extending your display allows you to see your desktop across multiple screens, as opposed to mirroring it perfectly on another device. Luckily, with Deskreen enabled, we have a second screen to extend!
  9. Step 9 Start working with your dual set of monitors.

    Now, your MacBook should be functioning as a second monitor for your PC. To test it, drag any window to the edge of the page until it disappears. It should then appear on your second screen (i.e., your MacBook).

  1. Step 1 Purchase a USB video capture card.

    This is a device that you can plug into your MacBook, allowing it to act like a camera that can capture display information from another computer. This option is both effective and fairly inexpensive.

    • You can get a decent video capture card for around $20 USD.
    • Depending on what kind of USB ports your MacBook has, you may need to buy a USB-C adapter (or purchase a video capture card that comes with one).
  2. Step 2 Download OBS on your MacBook.

    OBS is an open-source broadcasting app that you can use to stream data from your PC to your Mac via the video capture card. Download it from the OBS website, open the installation file, and follow the prompts to install it on your Mac. You’ll need macOS 11 or later.

  3. Step 3 Plug the video capture card into your MacBook.

    Plug it directly into one of your USB ports or use an adapter, depending on what kind of USB ports your MacBook has.

  4. Step 4 Connect your PC to the video capture card with an HDMI cable.

    Locate the video output port on your PC and plug an HDMI cable into it. Plug the other end into the HDMI port on your video capture card.

    • If your PC doesn’t have an HDMI port, you may need to use a USB-C or Mini DisplayPort adapter.
  5. Step 5 Launch OBS on your MacBook.

    You’ll be using it to view the stream from your PC.

  6. Step 6 Choose Video Capture Device as your input source.

    Locate the Sources Dock at the bottom of the main app window, then click +. From the list of options, choose Video Capture Device.[6]

  7. Step 7 Select your device from the dropdown menu.

    A new window should open, prompting you to choose a video capture device. Click the dropdown menu to select it. Your device may have a name like “USB Video.”

    • You can also select a custom resolution or choose Use Preset. When you’re done, click OK.
  8. Step 8 Switch OBS to full screen mode.

    Right-click the preview window and select Full screen projector (preview). In the sub-menu, choose Built in Retina Display. You should now see your PC’s screen on your MacBook!

  9. Advertisement

  1. Step 1 Download an app that enables Airplay on your PC.

    Airplay is a feature that makes it incredibly easy to cast your screen to and from various Apple devices. Although Windows PCs don’t come with built-in Airplay capabilities, there are several third-party apps that can make your PC into an Airplay sender or receiver. While you generally have to pay for these apps, some of them offer free trials.

    • Some popular options include AirParrot and AirMyPC.
    • Check the documentation that comes with the app to make sure it allows you to cast from your PC to an Airplay device.
    • Follow the installation instructions for your chosen app.
  2. Step 2 Enable your Mac as an Airplay receiver.

    You’ll need to have macOS 12 or later installed on your MacBook for this to work.[7]

    • Go to
      Mac Apple

      Apple menu > System Settings and select General from the left menu pane.

    • Click AirDrop & Handoff in the main menu on the right.
    • Toggle on Airplay Receiver.
    • Click the menu next to Allow Airplay for and select Anyone on the Same Network.
  3. Step 3 Make sure your MacBook and PC are on the same network.

    Airplay uses Wi-Fi to connect two devices together, so you’ll need to ensure that both your computers are logged into the same network.

  4. Step 4 Open the Airplay app on your PC.

    With most of these apps, you’ll find the app icon in the System Tray at the bottom right corner of your screen, near the clock. Click the icon to open the app menu.

  5. Step 5 Select your MacBook from the list of available receivers.

    Your Airplay app should now begin casting to your MacBook! Use the tools in the app menu on your PC to select whether to mirror or extend your screen, stream just a specific app to your MacBook screen, and so on.

  1. Step 1 Install Duet Display on both your computers.

    Duet Display is an app that allows you to share your screen by turning your computer into a remote desktop. You’ll need to download and install the software on both your MacBook and your PC to use it, and log in with the same account on both devices.[8]

    • While this app has the advantage of being easy to use and not requiring any additional hardware, you have to pay a subscription fee to use it, although there is a free trial available.
    • You’ll need to have Windows 10 or later on your PC and macOS 11 or later on your MacBook.
  2. Step 2 Open Duet and log in on both devices.

    The app must be running and you have to be logged in simultaneously on both your PC and your Mac.

  3. Step 3 Locate your Mac in the Connect Devices tab.

    In the Duet app on your PC, look for your MacBook in the list of available devices. If you don’t see it listed, make sure both computers are on the same Wi-Fi network. You can also go into the Settings tab and make sure Screen Sharing Enabled is checked on both devices.

  4. Step 4 Click Mirror or Extend.

    To extend your PC’s screen to your MacBook, click Extend. To show the same view on both screens, select Mirror instead.

  5. Step 5 Click Connect.

    Your PC should now begin sharing its screen to your MacBook! You can make adjustments to display settings such as the frame rate, performance, resolution, and scale in the Duet window on your PC.

  1. Step 1 Purchase a Luna Display dongle.

    This is an easy and versatile option, but it’s also fairly expensive. To start, you’ll need to buy a Luna Display, which is a dongle that you can plug into a USB-C/Thunderbolt port on your PC. You can buy it here.

    • Unfortunately, this dongle doesn’t work with adapters. You’ll need a PC with a USB-C port that supports Thunderbolt or DisplayPort.[9]
  2. Step 2 Connect your PC to your MacBook with an ethernet cable.

    While you can use Luna Display wirelessly, you’ll get a better performance if you have a wired connection. If you don’t have an ethernet port on your MacBook, you may need to use an adapter or hub to connect your computers.

  3. Step 3 Install the Luna Display app on your PC.

    Luna Display is the app you’ll need to use on your primary computer. You need Windows 10 64-bit or later to run it. Run the install file and follow the prompts to install it on your PC.

  4. Step 4 Install Luna Secondary on your MacBook.

    This is available on the same download page as Luna Display.

  5. Step 5 Launch the apps on both computers.

    They should automatically detect each other, and your MacBook will now be configured as a monitor.

    • From here, you can experiment with the settings in the Luna Display control panel to find what works best for you. It is recommended that you enable the Retina Resolution option for the best results.

Macbooks and PCs have rivaled for many years, and the two computers don’t get along too well. A different operating system, architecture, and hardware design can be hard to work with the two computers together.

That’s why most Mac mini, Macbook Air, and Macbook users find it hard to work with Windows applications and vice versa. However, there is an interesting problem where you might need the two devices to work together.

Using Macbook as External Display for PC

When you’re in your school or office, your colleagues may have a Macbook, while you could be a Windows machine lover. What if you need to use the Macbook as a display for your PC?

Fortunately, there is a way to extend or mirror your screen to a Macbook and vice versa.

Why Do You Need External Displays

While working on multiple applications, running out of space on the desktop is possible. As a result, you’re forced to minimize applications and use them sequentially. Unfortunately, that involves a lot of navigation which can often become too frustrating for the users.

Hence, when you have dual monitors, it can provide much-needed screen real estate to work with.

Likewise, if you need to present something on a screen, a mirror screen will ensure you won’t carry your laptop around the table to show everyone what you’re doing.

Connecting a PC to another PC via HDMI ports is pretty straightforward. Likewise, you can connect your Macbook air with another Mac device. But what if you have a Macbook as a second monitor? How do you connect a PC to a MacBook to extend or mirror your display?

Find out the answers in this post.

How to Use Macbook as a Second Monitor without the HDMI Port

You guessed it right! How can you connect Macbook to a PC when Macbooks don’t have HDMI ports?

The idea of an HDMI cable becomes useless because most Mac devices have no such display ports.

Only Mac Mini has an HDMI port, but there is a problem. The Mac mini DisplayPort is an output-only display port, so you can’t use it to send signals from a PC.

Although there are some hacks, like using an adapter to connect the devices for external display, it doesn’t give the desired signal quality, so it’s not all that efficient.

Additional Hardware Often Causes Hardware Damage

The problem with additional hardware is the high chance of hardware damage. Often, users end up damaging HDMI ports or loose connectors.

Therefore, additional adapters for external display are not the most efficient option for connecting Macbook with a PC.

MacBook as a Second Display for Windows Machine without HDMI Ports

Even though HDMI ports are not an option for Macbooks, a wireless display is an easier and more efficient way to connect it to a Windows PC. It means you can conveniently move your MacBook around and still receive quality input from the PC.

Here is how to do it:

  • Use Deskreen Software Application with a Virtual Display Adapter
  • Use a Video Capture Card for Macbook

Using Deskreen Software to Connect Macbook as an External Monitor for PC

First, to use Deskreen as a display software for your Macbook, ensure a stable Wi-Fi connection. The software uses Wi-Fi signals to turn any device into an external display.

As a result, you can extend your desktop screen to one external display. More importantly, this application works well with Mac computers without needing installation and provides a stable video output every time.

To use Deskreen for making your Mac computer a secondary display to your PC, follow these simple steps.

Step 1 – Download the Official Deskreen App

Start by downloading the Deskreen app from its official website. You will need to install the app on your Windows PC only. The installation process is straightforward, so you need to follow the on-screen prompts.

After installation, you should receive an IP address from the app. So, you can use this IP address to connect your Mac to the PC and turn it into a second screen through the Wi-Fi signals.

Step 2 – Adding a Virtual Display Adapter

Screen projection software like Deskreen and several others rely on a small device called the Virtual Display Adapter. These adapters are small dummy plugs that act as an external computer display.

It’s pretty easy to find these adapters, and they are affordable too. So, go on and connect the VDA USB device to your PC.

Step 3 – Launch the Deskreen Application

Next, you need to launch the Deskreen software on your PC. The application will provide a QR code and an IP address that you will use to connect the Macbook. The IP address is handy when you’re joining the Macbook. And the QR code is useful when you project a display to an iPad or iPhone.

You must ensure that both devices are connected to the same Wi-Fi network.

Step 4 – Access the Provided IP Address

Launch the web browser, Safari, or any other, and enter the provided IP address. Press Enter to connect to the PC.

Step 5 – Grant Access to Macbook for Display

When you enter the IP address, you should see a message on your PC screen warning you about the display request from a Macbook. Click the ‘Allow’ button to enable a second monitor for your PC.

Here, it would be best to share the Entire Screen. You can also choose to share a specific application to the secondary display.

Step 6 – Pick the Second Screen Option

You will get two screens on display when you choose the Entire Screen option. One will be your Desktop, while the other should be a blank screen.

The blank screen is where you can project your desktop screen. So, to extend the display to your Macbook screen, click on the blank side of the screen.

Step 7 – Choose your Projection Settings

Once you click the blank section, you can choose how to protect your PC screen from the Macbook. For that, press Windows + P; you should see a side panel on the Windows machine.

Here, you can choose from the following settings:

  • The ‘PC Screen only’ setting will disable the display on the Macbook.
  • Choose ‘Duplicate’ to share your screen with your Macbook. This option is useful when you are presenting files to an audience.
  • Choose ‘Extend’ to create more space on your desktop. This option allows you to drag files from one screen to another. The’ Extend’ option is helpful when working with multiple applications and needing additional display space.
  • Choosing the ‘Second Screen Only’ will turn off your Windows screen, and you will only see the output on the second screen. It’s useful when displaying content on Mac computers and saving power on your Windows desktop.

Using the Video Capture Card to Connect Macbook as an External Display for Your Windows Machine

You can also use the video capture card to transmit video signals to your Mac mini or Macbook pro. You won’t need a mini DisplayPort cable to connect to the Mac mini as a second monitor.

The video capture card is much like a mini HDMI device and is widely used for game console streaming. However, you will need a USB-C to USB-A adapter when you connect the video card. That’s because Macbook only has USB C ports.

Once you connect the card to the Macbook, here is what you must do.

Installing the OBS to Macbook

After connecting the card, you must install the OBS and launch it on the Macbook. Then, on the bottom of your screen, locate a menu where you will see a plus sign.

From there, choose ‘Video Capture Device’ and give a name to your device. Then, choose your device from the given list, so you must choose your device to capture video output.

If you don’t see your device name in the list, there must be a problem with the hardware drivers, so you must install the relevant drivers before proceeding.

  • Set the video capture settings to YUY2 video format
  • Set 1920 x 1080 video resolution.
  • Disable buffering
  • Choose a partial color range.

Once the settings have been adjusted, you can capture video from your Windows machine.

Can You Connect Two Macs Using Target Display Mode?

The target display mode was a setting in the older Mac devices. With the target display mode, mac users could connect two MacBooks where one would work as the second monitor for display.

However, modern Macbook devices don’t feature the Target display mode, as Apple got rid of this feature as it would require numerous Thunderbolt ports to work.

Conclusion

Connecting Macbook as a secondary display to a Windows desktop could make your life easier when you want additional desktop space. Moreover, sharing the screen for presentations and similar tasks makes it more accessible.
