Description Samuel 2024-02-24 14:48:06 UTC 
Kernel version used: 6.7.5

Using a display1.2 port to display1.4 port on the dock I'm not able to get 240hz on linux I max out at 165hz

On windows with the same dock and montior I get 240hz 

I've tested 3 wayland compositors which all had the same results.


Cpu: 7940hs, usb4 port with 40gbs
