Tabbycat: Is this really the thread where you responded to *MY* post with a request for more info? (Asked in a private message.)
I don't see such a question and my post doesn't even seem to be the type where more info would be requested (I just want a HIGH CONTRAST display with minimal highly contrasting colors and the highest resolution availabl, largest lettering etc. so I can read it during the night without glasses and while half awake and from odd angles.)
As to the problem: Why not the obvious? Get some heavy, black construction paper (or similar) and build a little cover that can be flipped back easily to view the screen and/or humidifier chamber. Tape on.
Start the machine, view what you need, and flip it (or them) closed.
There is no significant heat being expelled in those areas so it should cause no problem to do this but test just a little to make sure.
