Thanks for your work

I just bought and tried a new 4K hdmi cable, with no change. I noticed that the monitor has TWO inputs, HDMI and HDMI/MHL (it had been plugged into HDMI) but switching this to HDMI/MHL gave no result.

I am using MATE but the same issue occurs in several flavours of Ubuntu that I have tried.

I dont know how to try the new kernel at
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/ as you requested. If I attempt to ask Gdebi to load the linux-image-unsigned-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb package from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/ it fails with unmet dependencies.

kernel-modes.txt is attached
