@Grigory_Malkov @bnjns @Techie_Zeddie you all seem to be experiencing the same issue that myself and others are experiencing in this thread: [RESPONDED] AMD Mainboard: Caldigit TS4 dock monitors not identified
The common thread seems to be amdgpu on Ryzen 7000 chips failing to detect EDID for monitors connected through USB4 docks.
There are bug reports here:

Unfortunately the AMD chips just have worse compatibility than the Intel chips currently, and you’re rolling the dice depending on what dock and monitor you’re using. I would recommend against AMD for anyone who needs to use external monitors at this point.
I had a Pluggable TBT4-UDZ dock that worked fine with the 11th Gen Intel Framework. But didn’t work at all with the 7840u Framework. So I bought a Caldigit TS4 dock, which works with my Alienware monitor on the 7480u Framework, but has the EDID issue with my BenQ monitors.
Both docks work perfectly with both monitors on other systems. It’s just the combination of AMD 7000 on Linux that is problematic.
