Methods to connect your iPad as an external HDMI display
The iPad can function as an external display for a Mac in a variety of ways, from Apple's own solutions to third-party apps and physical adapters. Choosing the best method depends on your needs, available hardware, and the version of macOS and iPadOS you're using.
1. Connection via HDMI cable and adapters
The most traditional method for using your iPad as an external HDMI display involves physically connecting both devices using compatible cables and adapters, what it offers you high image quality and low latency. These are the basic steps:
- Connect an adapter to your iPad's port (This can be a USB-C to HDMI adapter if your iPad has USB-C, or a Lightning to HDMI adapter if it's an older generation.)
- Connect the HDMI cable to the adapter and the external monitor (whether it's a separate display or the Mac itself, if you want to mirror the image from your Mac to your iPad, you'll need a capture card that can forward the signal to the iPad.)
- When everything is connected, The iPad should automatically recognize the external monitor. and start mirroring your iPad screen (or your Mac, if you're using a compatible video capture device).
Attention: Not all iPad apps support mirroring, so you'll sometimes see a black screen in unsupported apps. Additionally, image quality will depend on the adapter, cable, and monitor used.
If you are looking for a simple and direct solution, USB-C to HDMI cables will allow you to avoid intermediate adapters, as they come with both connectors built in. Just plug the USB-C into your iPad and the HDMI into your external monitor.
2. Use iPad as a Mac display with Sidecar
Apple implemented Sidecar as a native feature since macOS Catalina to extend or mirror the Mac display on a compatible iPad. It's the smoothest, most stable, and lowest-latency option for using your iPad as an additional monitor.
- Requirements: Both devices must be compatible with Sidecar and signed in with the same Apple account.
- You can use Sidecar wirelessly, but connect iPad to Mac via USB cable ensures greater stability and performance in video transmission.
- To activate Sidecar: Simply hover over the full screen button on any window on your Mac and select the option to move it to your iPad.
- You can choose to extend your Mac desktop or mirror it on your iPad using the Display Mirroring options in the macOS menus.
- The iPad sidebar will display essential Mac controls, such as Command, Shift, and other modifier keys accessible with your finger or Apple Pencil.
Sidecar also supports useful Multi-Touch gestures, such as two-finger scrolling, three-finger copy, cut, and paste, undo and redo with specific side gestures, and works seamlessly with Apple Pencil for precision tasks like drawing, editing photos, or manipulating objects.
Another important advantage: If your Mac doesn't have a physical Touch Bar, Sidecar gives you a virtual Touch Bar on your iPad, accessible by touch or with the Pencil. You can adjust its visibility from Sidecar preferences.
Sidecar automatically turns off if you open an iPad app outside of Sidecar, but you can simply return to the Sidecar app to continue using your iPad as an additional display.
Recommended settings in Sidecar: You can configure sidebar visibility, Touch Bar location, and enable double-tap on Apple Pencil (2nd generation) to further customize your experience.
Third-party apps to turn your iPad into an HDMI monitor
Beyond the official options, there are apps on the App Store that allow you to connect your iPad as an HDMI display for any device, including your Mac. These apps are especially useful if you're looking for extra features or if your Mac/iPad doesn't natively support Sidecar.
Orion Video System: The app that turns your iPad into an HDMI monitor
Orion Video System is a free app that turns your iPad with USB-C port into a full HDMI monitor, for both computers and consoles, cameras and other devices.
- You only need a iPad with USB-C and a USB-C video capture card with HDMI input.
- Simply connect the HDMI cable from your Mac to the capture card, and then connect the capture card to the iPad via USB-C.
- The app displays the video signal in real time, with quality up to 4K enhanced by artificial intelligence (premium feature).
- Includes filters to simulate CRT screens (ideal for retro gaming or emulators) and does not include intrusive ads or collect user data.
- The free version covers the core functionality, but if you want extras like 4K upscaling or more filters, you have a one-time in-app purchase.
The cost of a USB-C to HDMI capture card is very affordable (they can be found for around 15 euros on Amazon), making this solution a versatile, compatible, and portable option.
Other ways: Wireless connection via AirPlay and HDMI
If you prefer to avoid cables, there are devices that allow you to send the HDMI signal from your Mac to the iPad wirelessly, Although the iPad doesn't officially support direct wireless HDMI input, the usual approach is to send the Mac's display to a monitor via AirPlay and clone the image to the iPad using compatible apps or wireless adapters that act as a bridge.
To share your iPad screen via Wi-Fi, you can use AirPlay by accessing the iPad Control Center and selecting "Screen Mirroring," then choosing a compatible device. This method primarily works for mirroring, not extending, your desktop, and quality will depend on your Wi-Fi network.
Audio and display settings
Once you've connected your iPad as an external display, either via cable, Sidecar, or an external app, you can configure the audio to your liking. To do this, simply go to 'Settings' > 'Sound & Haptics' > 'Audio Output' and choose the external monitor, which is especially useful in presentations or video conferences where the sound needs to come from the external device instead of the iPad.
If you use applications like iWork, you can take full advantage of the multimedia capabilities of the HDMI or Sidecar connection, including sound.
To optimize the viewing experience: Adjust the resolution from your iPad or Mac settings to improve image quality. If you're using Sidecar, macOS allows you to adjust resolutions and multitasking options from System Preferences (or System Settings in newer versions).
Compatibility, iPad models, and considerations
Apple currently markets up to five iPad lines, each with different capabilities for connecting external monitors. The iPad Pro (since 2018) is the most versatile, allowing you to connect an external monitor directly from its USB-C port. However, this port is unique and limits the ability to connect multiple displays simultaneously.
The iPad Air and 10th-generation iPad also allow direct connection, but only support one external display each. For the 9th generation and earlier, which use a Lightning connector, you'll need a special accessory for video output, and compatibility may be reduced.
Therefore, before purchasing any adapter or capture card, make sure your model is compatible and choose the appropriate accessory (USB-C, HDMI or Lightning as appropriate).
Practical tips to get the most out of connecting your iPad as an external display
- Always check that the cable or adapter used is of quality and compatible with your iPad model and monitor/Mac.
- Update both your iPad and Mac to the latest version of the operating system available, as this improves compatibility and features.
- Set extended mode whenever possible to enjoy more workspace instead of duplicating the image.
- Use Bluetooth keyboard and mouse on iPad for better multitasking and increased productivity, especially in office or design apps.
- If you are receiving the signal from a Mac with resolution or scaling issues, adjust your monitor settings. directly from the display preferences on your Mac or from the iPad options, although customizing the resolution depends a lot on the monitor manufacturer and iPadOS itself.
Limitations and recommendations depending on the iPad model
Despite its many advantages, the iPad still has limitations in the number of external displays it can manage, Especially compared to a Mac. iPad Pro, Air, or 10th-generation iPads only allow one external display per physical port; models with Lightning require additional accessories, and compatibility may not be guaranteed for all apps or resolutions.
If you plan to use the iPad as an extra display on a regular basis, invest in a good accessory and adapter, and consider the Pro range if you need maximum quality or professional utility.
Taking advantage of advanced features in iPadOS and macOS
Over the years, Apple has enhanced the multitasking capabilities of both iPadOS and macOS, making it easier to organize windows and streamline workflows between the two devices. Using Visual Organizer, you can manage windows and apps on the external display, resize them, arrange them on the canvas, and move files between your iPad and the external display.
The Dock and App Library let you drag apps and create sets of windows that are easily accessible, This increases efficiency in both office tasks and creative work or multimedia editing. Plus, you can natively drag and drop files between the iPad and the external monitor, streamlining collaborative work or document editing.
Which method should you choose? Advantages and disadvantages
The decision on which method to use depends on your device model, budget, and usage goal.
- HDMI cable connection: Simple, straightforward, and compatible with most models, but limited by the mirror mount, cable length, and quality.
- Applications like Orion Video System: They allow for more flexible use (especially for gaming, photography, or using the iPad as a universal display), but they depend on an additional accessory (USB-C to HDMI capture card).
