Universal USB-C Video Adapter

This USB-C to HDMI adapter delivers 4K video at 30 Hz with audio pass-through for Thunderbolt 3 and 4 hosts. It connects laptops, tablets and phones that support DisplayPort Alt Mode to any HDMI display without drivers or external power. The compact ABS housing is built for daily carry and improved heat dissipation.

Suits Thunderbolt 3/4 users with Alt Mode

Ideal for presenters, streamers and multitaskers who need a second screen on MacBook Pro 2016-2022, MacBook Air 2018-2023, iPad Pro, Surface Pro, Pixelbook, XPS 13/15 or Galaxy S23 Ultra. Not for devices lacking USB-C video output, for setups requiring higher refresh rates, or for bidirectional signal conversion.

4K at 30 Hz maximum output

The adapter tops out at 4K resolution and 30 Hz refresh, so it matches monitors and projectors limited to that spec. If your display or workflow demands a faster refresh rate, this model will not meet the requirement.
