I had an issue where one of my computer screens flickered then went black for 10 seconds or so before returning a couple of times a day seemingly randomly. I then got a headphone amp on my desk, and noticed the same thing happened every time I switched it on - it had a pretty chunky switch with a satisfying click, but I guess it also kicked out enough ESD to trigger the monitor? Armed with this theory, I replaced the bargin basement displayport cable I was using and now no longer have any screen flickering issues. I don't really know if it's better shielded or something, or I just happen to have moved things around to avoid the majority of the problem. I wonder how many things we blame on bad hardware/software are actually part of the environment - I know hyperscalers have talked about how ECC failure events are more common than "conventional wisdom", which likely means on non-ECC consumer platforms they are getting relatively regular silent memory corruption events.
