Introduction
Microsoft has recently introduced new guidelines for USB-C ports on WHCP-certified laptops and tablets with the Windows 11 version 24H2 update. These changes aim to eliminate the uncertainty and confusion associated with different USB-C ports and their capabilities, providing users with a more seamless experience when it comes to charging, data transfer, and video output.
Read on to find out more about how these new rules will impact your device and improve the overall user experience.
Microsoft is now putting an end to the guessing game some known as 'port roulette' – when you wonder if the USB-C port you've plugged your monitor into is actually ready for it. With Windows 11 version 24H2, Microsoft is rolling out new rules regarding all USB-C ports on WHCP-certified laptops and tablets. Now, these ports would do exactly what you expect: charge, transfer data, and output video.
- Data transfer – machines should offer at least USB 3.0 speeds (5 Gbps)
- Charging – USB Power Delivery support is required (equal or more to 4.5W on laptops, 7.5W on tablets)
- Display output – support for DisplayPort Alt Mode, so every port can connect to a monitor
How it's been so far
And this mess is what Microsoft is addressing with the set of new rules. Basically, USB-C is the connector type, and Thunderbolt (and USB4) are performance standards that use the USB-C connector. These standards add premium features like high-speed data transfer, support for dual monitors, and PCIe tunneling for external GPUs.
Laptop makers were allowed to advertise USB4 or Thunderbolt support if only one of the device's USB-C ports could deliver the features, while the rest were carrying limited functionality. The normal person had no way of knowing which one was which.
