Why USB-C is confusing

USB-C is only the shape of the plug. The same shape can carry charging only, data, video, or all three, depending on the device and the cable. Video over USB-C is usually called DisplayPort Alt Mode, and Thunderbolt ports always include it.

USB-C to HDMI not working?

• The port may not send video. Use the checker above.
• Only one of several ports may do video. Try each one.
• Some adapters with extra ports need their own power. Plug in the charger.
• For a monitor with a USB-C input, a basic charging cable often carries no video. Use one that lists video or 4K support.
• Set the TV or monitor to the input you plugged into.
