Since CRU clearly masking this issue (and assuming display EDID can change w/new firmware).

Could new monitor firmware be my fix?

It might. If it's stable after changing the range with CRU, then it might be a driver bug. The buggy firmware on the monitor could be causing an unstable or incorrect DisplayPort signal that the driver is not handling correctly. I don't think audio has anything to do with the problem. Since the monitor also has HDMI, it might be worth checking to see if the problem also happens with HDMI.

Thanks. Buggy firmware means incorrect code structure within it's own stack correct?

I am still completely stable with CRU albeit 8 bit color no HDR. I will next try HDMI 2.1 cable RTX 3070 to Y27Q20, coming in the mail. This will also allow me to connect to my LG C9. If not that then I will load the beta Lenovo Y27Q20 firmware supplied to me from Lenovo. If neither those I will be at a loss but I am never at a loss for ideas.

Question: My CRU settings reset at some point again to default (maybe PC power cycle etc.).

Even though I have a modified profile ready in CRU (asterisk) it will not stick by selecting and clicking ok, then resetting with CRU 64.exe. If I redo a new custom profile and then 64.exe restart it sticks.

Why can't I just select modified settings from dropdown, click ok, and rest 64.exe?
