Odd Issue

[alaraajavamma]

Does the Modem radio frequency affect the HDMI Frequency? Reason I ask is with nothing done, Convergence works fully now using Manjaro and PmOS. Is there a way for me to see which Modem band I am currently using? I am curious as to why this issue is present at certain times.

Modem radio frequency is doing something to HDMI Freguency  - yes

I am also trying to learn so can't give you good answer.
There are some options and commands in modemmanager where you can choose and most likely see current frequency but as said I am also learning as I write. I can tell you if I find out how
