Monitor screen going blank or snow or Mac waking

HP Recommended
HP 32s Display
macOS 11.0 Big Sur

When I wake my Mac-mini (with the latest MacOS updates), only multi-colored snow shows up on the HP display. Other users indicated the same issue with Windows, so it's not an OS issue. It looks like a lack of syncing between the HP monitor and the HDMI signal from the computer. A display problem, not a computer problem. But whomever answer these questions on this board isn't addressing the issue and recommends the usual "check your BIOS" etc. Not helpful. 

My work-around: turn the display off, and turn it back on again: it restarts with a good picture. But this should be done by the display firmware, not the user.
