Connect iPad Pro to your Mac or other computer
You can connect iPad Pro to your Mac or PC to charge the device or sync content using iTunes.
First, identify the ports on your computer. If your computer is a more recent model that has a Thunderbolt 3 (USB-C) or USB-C port, connect to it with the USB-C to USB-C cable that came with iPad Pro.
If your computer has only USB-A ports, you need a USB-A to USB-C cable to connect to iPad Pro. One example is the mophie USB-A Cable with USB-C Connector; many other USB-certified brands available in your country or region might also work. The correct cable has connectors that look like this:
Charge iPad Pro
To charge iPad Pro, connect the included USB-C cable to the device's USB-C port and to the included 18W power adapter. Then plug the adapter into a wall outlet.
If you have a higher-wattage USB-C power adapter — such as the one that came with your Mac notebook — you can use it with iPad Pro, and you might see faster charging. Waltr 2 6 25 cm. You can also charge iPad Pro by connecting it to the USB-C port on your computer.
Connect to displays and monitors
The USB-C port on iPad Pro connects to external displays so that you can watch video, play Keynote presentations, and more on a larger screen. Depending on the display that you're connecting to, you might need an adapter.
When you connect an external display, it mirrors the iPad Pro built-in display, unless you're using an app that has a 'second screen' experience (such as a video app).
USB-C displays
iPad Pro uses the DisplayPort protocol to support connections to USB-C displays with resolutions up to 5K.1 To connect iPad Pro to high-resolution displays, use a USB-C cable that supports high-bandwidth connections, such as the cable included with the display, the Belkin USB-C to USB-C Cable, or the Apple Thunderbolt 3 (USB-C) Cable (sold separately).2
iPad Pro also supports high-dynamic-range USB-C displays that use the HDR10 standard. You can switch between SDR and HDR modes by going to Settings > Display & Brightness and selecting your connected display. iPad Pro matches the frame rate and dynamic range of currently playing content when you turn on Allow Display Mode Changes.
Some USB-C displays can also charge iPad Pro while it's connected.
1. iPad Pro supports the 2019 LG UltraFine 5K Display at 4K resolution with video, audio, data, and power. iPad Pro doesn't support Thunderbolt 3 displays such as the 2016 LG UltraFine 5K Display.
2. The Apple Thunderbolt 3 (USB-C) Cable has a Thunderbolt symbol to distinguish it from a USB-C cable.
HDMI displays or TVs
You can connect iPad Pro to an HDMI display or TV with a USB-C to HDMI adapter. Adapters that support HDMI 2.0 can output video from iPad Pro at 4K resolution and 60Hz.
The Apple USB-C Digital AV Multiport Adapter is also compatible with iPad Pro. This adapter can output video from iPad Pro at up to 4K resolution and 30Hz.*
iPad Pro can output Dolby Digital Plus audio streams via HDMI, but not Dolby Atmos. Also note that iPad Pro will play HDR10 or Dolby Vision content via HDMI when HDMI 2.0 adapters that support these formats become available.
Custom Keyboard Cable
* When you use the Apple USB-C Digital AV Multiport Adapter with iPad Pro, its Home screen and apps appear on HDMI displays at 1080p and 60Hz. When you begin playing video content, the resolution switches to match the content, up to 4K at 30Hz. Turn on the Match Content option on iPad Pro in Settings > Displays.
Play audio
To play audio on iPad Pro, you can use its built-in speakers, connect to AirPods or other Bluetooth devices, or use AirPlay. You can also use the USB-C port to connect to USB-C docks, audio interfaces, or wired headphones that have a USB-C connector.
If you need to play audio through the USB-C port to other speakers or headphones, connect using the Apple USB-C to 3.5 mm Headphone Jack Adapter (sold separately).
Connect to other devices

Use iPad Pro to charge other devices
Away from a power outlet and need to charge your iPhone, other iPad, Apple Watch, or third-party USB device? Just connect the right cable or adapter to iPad Pro to share its long-lasting battery with your other devices:
- To charge your iPhone or earlier-model iPad that has a Lightning port, connect it to iPad Pro using the Apple USB-C to Lightning Cable. If you have a Lightning to USB cable, you can combine it with the Apple USB-C to USB Adapter, then connect the adapter to iPad Pro.
- If you have two iPad Pro models with USB-C ports, you can connect them directly with a USB-C cable. One iPad Pro will draw power from the other. If you want to change which iPad Pro charges, unplug the USB-C cable and then reconnect them.
- Charge your Apple Watch by connecting its Magnetic Charging Cable to iPad Pro via the Apple USB-C to USB Adapter. If you have an Apple Watch Magnetic Charger to USB-C Cable, you can connect it directly to iPad Pro.
