Rocstor USB-C to 4K HDMI Adapter

The Rocstor Y10C129-B1 adapter converts a USB-C or Thunderbolt 3 port into an HDMI output. It supports 3840x2160 resolution at 60Hz for a crystal clear video feed. The six-foot cable connects laptops such as a MacBook or Chromebook to an Ultra HD display or projector. It is also backward compatible with 1080p screens.

Suits single-display USB-C laptops.

This adapter suits users who need one external 4K 60Hz screen from a USB-C or Thunderbolt 3 port. It works well for presentations, office work and home entertainment. Buyers who require multiple independent displays from a single port should look at a dock or hub instead. The device does not add extra USB or Ethernet connections.

Plugs directly into a USB-C or Thunderbolt 3 port

No external power supply or driver installation is required for basic video output. The adapter frees up other ports on the laptop by handling the video link through the single USB-C connection. It fits into a bag alongside the laptop for mobile use with any HDMI-equipped display. Ensure the host port supports video alternate mode.

Questions about this item

Does my laptop need a USB-C or Thunderbolt 3 port to use this adapter?

Yes, the adapter plugs into a USB Type-C or Thunderbolt 3 port on the host device to output video.

Will it work with my older 1080p monitor?

The adapter is backward compatible with 1080p displays, so it will downscale the signal to match that resolution.

How can I confirm the adapter is running at 4K 60 Hz?

Check the display settings on your computer; they should show 3840x2160 at 60Hz when the adapter is connected to a compatible 4K screen.
