Once both devices are updated and compatible, you can use the Sidecar feature to extend or mirror your Mac Mini's display to your iPad wirelessly or with a USB-C cable.

Setup Process

Here are the steps to use your iPad as a monitor for your Mac Mini:

Using Sidecar (built-in to macOS)

Connect your iPad to your Mac Mini using a USB-C cable.
On your iPad, go to Settings > Displays > AirPlay & Handoff and turn on "Allow Mac Display" and "Sidecar".
On your Mac Mini, go to System Preferences > Displays and select your iPad from the list of displays.
Choose whether to mirror your Mac's display or extend it to the iPad.

Using Luna Display (hardware dongle)

Connect the Luna Display dongle to your Mac Mini's USB-C port.
Install the Luna Display software on both your Mac Mini and iPad.
On your iPad, open the Luna Display app and select your Mac Mini from the list of available computers.
Your iPad will now act as a wireless display for your Mac Mini.

Using Duet Display (software only)

Install the Duet Display app on both your Mac Mini and iPad.
Connect your iPad to your Mac Mini using a USB-C cable.
Open the Duet Display app on both devices, and they will automatically connect.
Your iPad will now act as a wired display for your Mac Mini.

Some additional tips:

For best results, use a recent iPad Pro model with USB-C.
You can use an iPad in "headless mode" by connecting a USB-C display emulator to fool the Mac into thinking a monitor is connected.
Connecting a mouse and keyboard to your iPad allows you to control the Mac Mini interface.
Placing your iPad in landscape orientation on a stand provides the best viewing angle.

With these methods, you can turn your iPad into a portable, touch-enabled display for your Mac Mini, enabling a highly mobile and versatile computing setup.

Using Your iPad as a Primary Monitor

Here is a concise guide on how to use your iPad as the primary monitor for your Mac Mini:

Hardware Needed

Mac Mini
iPad
USB-C to Lightning cable or USB-C hub with HDMI port
Dummy HDMI adapter (optional)

Setup Steps

Connect the Mac Mini to power and the iPad using the USB-C cable or hub.
On the Mac, go to System Preferences > Displays and select the "Mirror to iPad" option.
If using a dummy HDMI adapter, plug it into the Mac Mini's HDMI port. This tricks the Mac into thinking an external display is connected.
On the iPad, open the Sidecar or Luna Display app. It should automatically detect the Mac Mini and mirror its display.

Optimize Display Settings

In the Sidecar/Luna app settings, select a lower resolution like 1024x768 or 1060x756 to reduce lag and improve performance.
Disable password prompts on the Mac Mini to allow the iPad to connect automatically on boot.
Use a wired USB-C connection for lowest latency. Wireless works but may have some lag.
Ensure you have a strong WiFi connection if using wireless mode.

With this setup, you can use the iPad's touchscreen to control the Mac Mini, run macOS apps, and even use it as a Wacom-style drawing tablet. The Mac Mini provides the processing power while the iPad serves as a portable, touch-enabled display.

Using Your iPad as a Secondary Monitor

To use your iPad as a secondary monitor, you only need to use Sidecar, which has several advantages:

Increased screen real estate: Having an additional display allows you to view more content simultaneously, making multitasking more efficient.
Flexibility: You can extend your Mac Mini's desktop to the iPad, showing different apps or windows on each screen, or mirror the same content on both displays.
Touch screen capabilities: With Sidecar, you can use your iPad's touch screen and Apple Pencil to interact with Mac apps in new ways, such as sketching or signing documents.

To use your iPad as a secondary monitor for your Mac Mini, follow these steps:

Make sure both your Mac Mini and iPad are signed in with the same Apple ID and have Wi-Fi and Bluetooth enabled.
On your Mac Mini, click the AirPlay icon in the menu bar, then select your iPad from the list of available devices.
Alternatively, you can set up Sidecar in System Preferences > Displays, select your iPad, and choose whether to use it as a mirrored or separate display.
Once connected, you can drag windows between the Mac Mini and iPad, use the iPad's sidebar and Touch Bar, and interact with apps using your Apple Pencil.
To adjust Sidecar settings, such as moving the sidebar or Touch Bar, or enabling double-tap on Apple Pencil, go to System Preferences > Displays and select your iPad.

By using Sidecar, you can efficiently extend your Mac Mini's display to your iPad, taking advantage of the additional screen space and touch capabilities for a more productive workflow.

Advanced Tips and Tricks

Here are some advanced tips and tricks for using your iPad as a monitor for your Mac Mini:

Productivity Tips

Disable animations and transparency effects in macOS to free up system resources for smoother performance when using your iPad as a second display.
Use Mission Control or keyboard shortcuts to quickly move windows between your Mac Mini and iPad displays.
Customize the Dock and menu bar to show on both displays for easy access to frequently used apps and system controls.
Take advantage of the iPad's touch screen capabilities with apps like Duet Display or Astropad to use it as a graphics tablet for sketching and photo editing.

Adjust the brightness and color temperature of your iPad display using Night Shift or a third-party app like f.lux to reduce blue light exposure in low-light conditions.

Troubleshooting Common Issues

On your Mac Mini, go to System Settings > Displays and click "Add Display". Your iPad should appear as an option.
Select your iPad and choose "Use As Separate Display" to extend your desktop, or "Mirror Built-in Display" to mirror your Mac's screen.
If your iPad doesn't appear, try restarting both devices.

Troubleshooting Display Issues

If the display is laggy or low quality, go to System Settings > Displays on your Mac and select "Optimize for iPad" under the iPad's display settings.

You can also set the iPad to mirror your Mac's display, which will keep the menu bar on the Mac's screen.
The iPad's display will automatically turn off when your Mac goes to sleep. Just wake your Mac to reactivate the iPad display.

By following these steps, you should be able to easily set up your iPad as a secondary display for your Mac Mini and troubleshoot any connectivity or display issues that arise.
