There are exceptions, such as using Caldigit’s USB-C SOHO Dock that uses separate lanes for both video and USB, and so can reach 60Hz. 4K video over USB-C is also limited to 30Hz screen rates. Macs are mostly limited to just one external display over USB-C because they don’t support Multi-stream Transport (MST). Many modern monitors now even have their own USB-C ports so can connect directly using a USB-C cable. USB-C’s Alternate Mode (aka “Alt Mode”) for video enables adapters to output video from the USB-C port to HDMI, DisplayPort, VGA and other types of video connectors on displays, TVs and projectors. It can send DisplayPort signals over the same cable and connector as USB signals, so users can hook up external displays with it – if their computers supported it. Since then, weve moved on from USB 3.0 which is now. USB-C is smaller than USB-A with a fast data-transfer rate and can carry up to 100W of power. It was a big improvement from USB 2.0 which first arrived in 2000 with transfer speeds of only 480 Mbit/s. Indeed, modern laptops often feature just USB-C or Thunderbolt ports, meaning you’ll need a USB-C docking station, Thunderbolt docking station, or USB-C hub to connect devices with other connections.
