I want to turn off the LCD screen and its LED backlight to prevent it from

turns back on, a few seconds later. It's subtle, because the screen displays a

@jmairey Sorry, but I disagree.
Well, first of all, I have to agree with you on one thing: these
settings are confusing, yes. But I doubt you found the solution to the
problem.
REMINDER: When you do tests, don't forget to "undo" your workaround,
obviously!

@vanvugt I tried adding
