Yes, the USB-C to HDMI 2.1 8K Cable works with compatible iPad Pro models, but some cases can block the USB-C connector from fully inserting.

• The USB-C connector needs a direct, full connection to the iPad Pro.
• If your case blocks the connector, remove the case before connecting.
• 8K video output is not supported on iPadOS.
