You mentioned "intermediate adapters". I'm using a Lenovo Ultradock between my laptop and the monitor. This causes no trouble on my Acer B326HK, which is just as high-res, but the new Samsung monitor continues to do the blackout thing. It's not strictly reproducible so far (fullscreening does not always cause any problem, and is not required to cause the problem).
Happily, I have two ultradocks. It happens with both! And the brand new HDMI cable looks fine. I cannot try without the ultradock because my laptop does not have an HDMI port. No one else has reported this problem, though if it's a hardware fault with the monitor (my interpretation) then it might be rare. I have recently upgraded to 21.04 and Wayland. I am wondering: Should I buy an adapter from HDMI to VGA, if such a thing exist? You would be generous to give this any more attention.
