Diagnose an iPad that shows no picture over USB-C
Check the iPad model, adapter and display input using the Home screen or a personal clip before testing the streaming service.

Check what the cable carries
Confirm Apple lists external display support for the exact iPad and the connection you want to use. A USB-C cable used for charging can have different video capabilities from a cable made for an external display. For an HDMI television, identify the adapter and select its HDMI input manually. Connect directly where practical and test with the iPad Home screen before opening any streaming app.
Separate basic output from app playback
If a personal clip appears correctly, keep the same adapter and input and try the programme again. A picture that goes black only in one service app can depend on that app or its external-playback rules. If nothing reaches the display, try a compatible cable or input and check Apple’s model-specific guidance before buying another adapter. Note the iPad model and adapter when asking for help.
