This is because DisplayPort video can be carried more efficiently on the USB-C connection than HDMI for the same resolution and refresh rate.ĭualMode DisplayPort++ connectors are able to function as HDMI connectors with a simple passive adapter (it does 3.3V to 5V level conversion). I strongly suspect most hubs with an HDMI port are actually implemented internally as a DisplayPort, with an integrated DisplayPort to HDMI converter. You’ll never find a USB-C hub that offers better video capabilities through its HDMI port than through its DisplayPort, but you will find hubs that offer better DisplayPort resolution and refresh rates. Lesson 1 is to focus on DisplayPort video connections, and forget about HDMI. October 2020 Update: see the notes at the end of this article about how DisplayPort 1.4 changes the landscape.
