Hello!
Do you get some info from dmesg?
It is kind of known issues that mobile broadband causes some problems to HDMI out.
Kind of because it is somehow rare and not documented (my guess is most likely because people are still using PP/PPP as testing/developing machine rather than full time daily use convergence thing so they don't notice this)
And this is absolutely strange - for example my case:
Most of the places "convergence aka. external display" is absolutely unusable if I am using 4G network.
After switching to 3G, 2G or turn off mobile broadband external display works perfectly.
BUT I have one place where I can use 4G network and external display works without flickering etc.
So it is somehow related to radio frequency and cable protection or something.
I have 6 Pinephones and so many docks and monitors that I can't even count. On every device there is this same problem no matter what OS/Modem firmware etc. there is running
