Help me troubleshoot my new workstation config?
Thinkpad with Thunderbolt 4 > CalDigit TB3 Plus dock > UGREEN Revodok Pro connected to the CalDigit's downstream TB3 port. 4k TV (120Hz capable) plugged into that via HDMI.
In 1920x1080 mode, I can go up to 120 Hz.
In 4k mode, I can't go any higher than 30 Hz.
If I plug the UGREEN Revodok Pro directly into the Thinkpad's other TB4 port, I can specify 60Hz, but I get screens like what you see here.
The Revodok also has two devices plugged into downstream USB3 ports: a microphone and a speaker.
I'm using #Fedora42 with #KDE Plasma 6.4.2.
Please #boost !
