Based on the title, I expected this to somehow be related to "Office chair turns off monitors" (it wasn't, but that is also a good one).

[Edit: I see this one has also been mentioned a few times already in the thread]
I had experienced this one and felt like I was going mad, and then I guess the humidity changed and I gave up/stopped thinking about it. It wasn't until a couple years later I saw a post here about the gas cylinders causing monitors to blank.
