Do monitors have any measurable power when they are off?
How much power do they use in sleep mode?

I have one, but IDK where it is at the moment. Why don't you just
look up the specs for the actual monitor in question? I would
expect it's zero or very close to that when off. The spec sheet
should have the power used when in sleep mode.
