[RESPONDED] AMD Framework : Portable Monitor won't work

Seems like the Kernal version 6.9+ seems to have issues with USB-C devices but 6,8.9 and below don’t seem to have the issue.

For some people powering the display separate from the laptop without using DP/HDMI Alt mode gets external displays working.

For me leaving the framework 65 watt usb-c power plugged in, plugging in the external monitor then unplugging the framework power cord and replugging it back in allows it to be detected on Fedora 41. Can’t speak for if any of the workarounds work for Windows.
