USB-C to HDMI 4K 60Hz Adapter

The Cable Matters 201088-B adapter connects USB-C, USB4, or Thunderbolt ports with DisplayPort Alt Mode to HDMI TVs, monitors, and projectors. It supports video output up to 4K at 60Hz and 2560×1440 at 144Hz. HDR video is delivered when the source device, OS, and display all support it. The unidirectional design works for phones, laptops, tablets, and desktops.

Suits portable display expansion not charging

This adapter suits users who need a compact, aluminium-housed dongle for daily connectivity at home, in the office, or while travelling. It works with iPhone 15, 16, and 17 series, Samsung Galaxy devices with DeX, iPad Pro and Air, MacBook, Surface, and Dell XPS systems. Buyers who require HDMI-to-USB-C conversion, USB-C monitor input, or power delivery charging should look at a different solution.

Sustained output via aluminium housing

The aluminium housing provides heat dissipation that helps maintain stable 4K 60Hz or 1440p 144Hz output during extended sessions such as long presentations, streaming marathons, or multi-hour work periods. The short, flexible USB-C pigtail reduces physical strain on the host port. Performance remains dependent on the host and display capabilities throughout the session.

Questions about this item

Which USB-C devices can I connect this adapter to for video output?

Connect phones, laptops, tablets, or desktops with USB-C, USB4, or Thunderbolt ports that support DisplayPort Alt Mode. The adapter works with iPhone 15, 16, 17 series, Samsung Galaxy, iPad Pro, MacBook, Surface, and Dell XPS devices.

Will the adapter downscale 4K@60Hz to 1440p@144Hz on an older 1440p monitor?

The adapter outputs the resolution and refresh rate negotiated between your source device and the connected HDMI display. If your monitor supports 2560×1440 at 144Hz, the host can drive it at that rate.

How can I verify HDR is active after connecting the adapter?

Check your operating system display settings or the monitor on-screen menu for an HDR indicator. HDR activates only when the source device, OS, and HDMI display all support it.
