This post to summarize the situation:
The issue : HDMI signal disappears (screen display : 'No Signal', the Raspberry is still running, I can connect to the AP and retake control with VNC.
I tried the same µSD card in another RPi 4 (4GB) not using the Argon case : same issue !
Seems the Argon case is innocent this time.
I noticed what looks like a bug with OC 5.2 : in the options of OpenGL, hitting the button 'Rebuild texture cache' results in the brutal closure of the 'Option' windows, so I stopped trying to use OpenGL with OC5.2, however the issue happened again though at a lower frequency (e.g. : after a few hours) !
All my tests have been done with 3 different µSD cards, all generated from 2020-03-24-OpenPlotter-v2-Starting-img.zip.
All µSD present the issue !
The power supply is a TOBSUN 5V 5A 25W, voltage measured in charge : 5.191 to 5.195 V : +/- 2 mV, always well higher than 5.1 V ...It is powered through an UPS.
