Features：

1. **Focused Function**: Specifically designed to detect whether a mobile device supports video transmission to a TV via the USB Type-C port, providing compatibility reference before purchasing a Type-C to TV cable or adapter, helping users avoid blind purchases.

2. **Easy to Use**: The tool is designed with user needs in mind, offering a low barrier to entry, making it easy for even non-technical users to operate. It also provides a consultation and assistance channel to resolve any usage questions.

3. **Clear Compatible Devices**: Known compatible devices from major brands (including Samsung, Huawei, Honor, HTC, and others) are clearly listed, allowing users with these devices to quickly confirm compatibility.

4. **Clear Technical Principle**: Based on USB Type-C's Alt Mode technology, it supports non-USB signal transmission such as DisplayPort. This explains how compatible devices can directly output video via a single cable, eliminating the need for additional adapters, demonstrating the practicality of the technology.

The standard allows for the creation of USB Type-C cables that do not require additional dongles or converters, enabling supported devices to directly transmit video from a USB-C-compatible device to a TV display using a single cable.

Alternative Mode, often abbreviated as Alt Mode, permits non-USB signals to be transmitted over a USB-C cable. Other Alt Modes for USB-C include DisplayPort, MHL, and Thunderbolt. Devices with USB-C that support these Alt Modes can transfer these signals along with standard USB data when used with the appropriate cable.

2. Q: Is this app difficult to use?

A: Not at all. Its design is user-friendly and has a low learning curve, making it easy for even non-technical users to use. Users can also seek help through consultation channels if they encounter problems.

3. Q: Which brands and models are confirmed to be compatible with Type-C video output?

A: Known compatible models cover many mainstream brands, such as Samsung Galaxy S8/S9/S10 series, Note8/Note9, Huawei Mate10/Mate20 series, P20/P30 series, Honor Note10, V20, HTC U Ultra, U11, etc.

4. Q: What is the technical principle behind the Type-C interface's ability to transmit video signals?

A: The core technology is **Alt Mode** based on USB Type-C. This technology allows non-USB signals, such as DisplayPort, MHL, and Thunderbolt, to be transmitted over Type-C cables. Devices supporting this mode, when paired with a suitable cable, can directly output video.

5. Q: Do I need an additional adapter to connect a Type-C device that supports video output to a TV?

A: If the device supports the corresponding Alt Mode, it can be directly connected to the TV to transmit video using a standard USB Type-C cable. No additional adapter or docking station is required.
