Introduction
This manual provides comprehensive instructions for the Amazon Basics Uni-Directional USB-C (Source) to HDMI (Display) Cable Adapter. This cable enables you to connect a USB-C enabled device (source) to an HDMI display (monitor, TV, projector) for high-quality video and audio transmission. Please read this manual thoroughly before use to ensure proper setup and operation.
Compatibility
It is crucial to verify that your source device's USB-C port supports DisplayPort Alternate Mode (DP Alt Mode) or Thunderbolt Full Functionality for video output. Not all USB-C ports are designed to transmit video signals.

This image illustrates USB-C port compatibility. Compatible ports include USB-C with Power Delivery + Display Alt Mode, USB-C with Display Alt Mode, Thunderbolt 4, and Thunderbolt 3. Incompatible ports are USB-C for Power Delivery only and USB-C for Data Transfer only.

This image shows compatible and incompatible devices. Compatible devices include laptops (Mac and Dell, any laptop supporting USB-C video output), phones (iPhone 15/16 Series, Samsung Galaxy S8 or later), tablets (all USB-C iPad, Surface Pro 9/8, Samsung Galaxy Tab S8/S9), and portable monitors. Incompatible devices include Samsung A Series phones, Nintendo Switch, cars, Fire Tablets, GoPro, cameras, Kindle, and devices with DisplayPort or USB Type A ports that do not support video output.
Setup Instructions
- Identify Ports: Locate the USB-C port on your source device (laptop, tablet, phone) and the HDMI input port on your display device (monitor, TV, projector).
- Connect USB-C: Insert the USB-C end of the cable into the compatible USB-C port on your source device. Ensure it is fully inserted.
- Connect HDMI: Insert the HDMI end of the cable into the HDMI input port on your display device. Ensure it is fully inserted.
- Power On Devices: Turn on both your source device and your display device.

Operating Instructions
Once the cable is securely connected and both devices are powered on, your display device should automatically detect the video and audio signal from your source device. You may need to adjust display settings on your source device (e.g., duplicate display, extend display) to achieve your desired screen configuration.
This cable is uni-directional, meaning it transmits video and audio exclusively from a USB-C source to an HDMI display. It does not support bi-directional transmission (HDMI to USB-C).
The cable supports 4K video resolution at 30Hz refresh rates. For optimal performance, ensure your source device and display are capable of these specifications.
Maintenance
- Keep the cable and its connectors clean and free of dust or debris.
- Avoid bending the cable sharply or placing heavy objects on it to prevent internal damage.
- Store the cable in a cool, dry place when not in use.
- Do not expose the cable to extreme temperatures or direct sunlight.
