What this adapter does

Plugable's USB-C to HDMI adapter adds an HDMI 1.4 port to a laptop, tablet or desktop that supports USB-C DisplayPort Alternate Mode. It is designed for users who want to connect an external monitor, TV or projector through a single USB-C or Thunderbolt 3 port.

Resolution and refresh limits

The HDMI 1.4 interface caps 4K output at 30Hz, delivering 3840x2160 at that rate. Lower resolutions such as 1920x1080 and 2560x1440 can run at 60Hz, so the adapter suits office work and media playback rather than high-refresh gaming.

Check your host before ordering

Your device must provide DisplayPort Alternate Mode video output over its USB-C or Thunderbolt 3 port. Most current phones and tablets with USB-C do not support Alt Mode, so they will not work with this adapter. Verify the host specification before purchasing.

Questions about this item

Should I pick this adapter if I need 4K at 60 Hz?

This adapter uses HDMI 1.4, which caps 4K at 30 Hz; 60 Hz is available at 1920x1080 and 2560x1440.

What does 4K 30 Hz actually look like on my monitor?

You get 3840x2160 resolution refreshed 30 times per second — fine for office work and video, but not for fast gaming.

Does HDMI 1.4 limit what I can connect?

Yes, the HDMI 1.4 port tops out at 4K 30 Hz; higher refresh rates at 4K need HDMI 2.0 or newer.
