Because it's hard to read a monitor that is off. So if the power goes
off. Also monitor is obviously at the mercy of whatever comes down the

Mine says:
95W (<8W in power-saving mode)

Possibly. I don't knwo if it will spike much / at all above eg 95W but
if it goes from eg <8W to 95W, that's an order of magnitude...

Surge protector instead?
it depends
