USB-C to 2 HDMI screens: what do you need?
It splits one video-capable USB-C port into two HDMI screens with no driver.
USB-C dual HDMI adapter
- Needs a USB-C port with DisplayPort Alt Mode and a graphics chip that supports DisplayPort MST. Many Windows laptops do, but check yours.
- Two screens usually share the port, so expect about two 1080p screens at 60 Hz, or two 4K screens at 30 Hz, on a typical laptop.
- On a Mac this shows the same picture on both screens; macOS cannot give two separate desktops this way.

Check your USB-C port first
Not every USB-C port can send video. Many phones and some laptop ports cannot. Look for a small screen or Thunderbolt lightning-bolt symbol next to the port, or check the spec sheet for DisplayPort Alt Mode or Thunderbolt. Some ports carry video without a symbol, so check your laptop’s specs if you are unsure. If you cannot tell and you use a Windows PC or Mac, pick the adapter that works on any USB-C data port; it works either way once its driver is installed.
Other options

It drives two HDMI screens over one USB-C connection, and shows a different picture on each, including on a Mac.
