Secomp USB Type-C to HDMI Adapter Cable S3730, USB-C to HDMI, 1 m

The Secomp USB Type-C to HDMI Adapter Cable S3730 is a 1 m wired connection designed to carry video from USB-C equipped laptops, tablets or smartphones directly to HDMI displays. The cable supports a single-cable solution for transmitting video and audio to monitors, TVs or projectors, enabling screen mirroring or extension without the need for separate adapters or docking stations.

Advantages

The cable delivers a simple plug-and-play connection that requires no external power or software on compatible hosts. Its 1 m length balances desktop convenience and reach, reducing clutter while providing enough flexibility to position a display. A direct wired link offers lower latency and more stable transmission compared with many wireless options, and the integrated HDMI output carries both high-definition video and audio in a single cable.

Suitable for

• Connecting a USB-C laptop to an HDMI monitor or TV for presentations
• Extending or mirroring a tablet or smartphone screen to a larger display
• Home streaming of video and audio from a portable device to a TV
• Classroom or meeting-room setups where a reliable wired video feed is required

When it may not be suitable

This cable requires a source device with an alternate mode USB-C video output (DisplayPort over USB-C). It will not provide a video signal from USB-C ports that support only power delivery or data without video alt mode. It is not designed as a charging-only cable and does not replace a multiport docking station when multiple peripheral connections are needed.

Key specifications

• Cable type: USB Type-C (male) to HDMI (male)
• Length: 1 m
• Function: Transmit video and audio from USB-C alt mode to HDMI display
• Connectivity: Direct wired connection, single-cable solution

How to use

Connect the USB-C end to a compatible device that supports video output over USB-C, then plug the HDMI end into the display’s HDMI input. Select the corresponding HDMI input on the display. On the host device, configure display settings as needed to mirror or extend the desktop. No drivers are typically required on modern operating systems; ensure the source device’s USB-C port supports video output before use.

What to consider before purchase

• Verify that your device’s USB-C port supports DisplayPort over USB-C (alt mode)
• Confirm the target display has an available HDMI input and supports the required resolution
• Consider cable length (1 m) for your workspace layout and reach requirements
• Check whether you need additional ports or power delivery that this single-purpose cable does not provide

Usage recommendations

For optimal performance, use with devices that explicitly list USB-C video output or DisplayPort alt mode. Avoid tight bends near the connectors and route the cable to prevent strain. If you require longer reach or additional connectivity (USB, Ethernet, power pass-through), consider a docking solution instead of a single-purpose adapter cable.
