Universal USB-C to HDMI Adapter

This 3 ft black adapter cable connects any USB-C device to an HDMI display using a female port. It supports smartphones, tablets and laptops including Samsung Galaxy, MacBook Pro and Surface Pro models. Plug-and-play operation requires no drivers or external power. The compact design suits home, office or travel use.

Sustained 4K 60 Hz Output

The adapter maintains a stable 3840x2160 signal at 60 Hz during extended sessions such as presentations, teaching or movie playback. Gold-plated connectors resist corrosion and preserve signal integrity over time. No digital compression is applied to 7.1, 5.1 or 2-channel audio streams. Performance stays consistent without thermal throttling or driver overhead.

HDMI 2.0 and DisplayPort 1.3 Alt Mode Limits

The female HDMI 2.0 interface caps video bandwidth at the 4K 60 Hz level, so higher refresh rates or resolutions are not possible. DisplayPort 1.3 Alt Mode carries the signal from the host, meaning the source must support that alt mode for video output. An additional HDMI cable is required to reach the display, adding its own length and quality constraints. Thunderbolt 3 hosts are compatible but do not extend the adapter's maximum resolution.

Questions about this item

Does the 3 ft adapter cable get warm or draw extra power when it drives a 4K 60 Hz display all day?

The adapter is passive and draws only the small amount of power the host USB-C port normally supplies for DisplayPort Alt Mode; it has no active electronics that generate noticeable heat during extended use.

What separate cable do I need to already own to connect this adapter to my monitor or TV?

You must provide a standard male-to-male HDMI cable; the adapter ends in a female HDMI port so an HDMI cable is required to reach the display.

Will the USB 3.1 Type-C connector work with an older laptop that only has USB 3.0 Type-A ports?

No — the adapter requires a USB-C port that supports DisplayPort 1.3 Alt Mode; a USB 3.0 Type-A port cannot carry the video signal even with a physical adapter.
