Title: leaving PC/presentation monitor on?
Post by: shorthair on May 14, 2007, 11:21:30 pm: A PC or presentation monitor will power down when there's no signal to it. Is it completely off, though? Is it okay to leave it this way 24/7?

LCD monitors can power down as low as 4 or 5 watts but an older presentation monitor will probably use more power when powered down. No worse then a regular TV when switched off I guess. If it has instant on it could use quite a bit of power keeping the tube warm.

Nothing detrimental.

But as others have said, different units draw different current and power in "sleep" mode so there could be some impact to the power bill...

Post by: BobA on May 18, 2007, 01:49:15 pm: Minimal electricity is used in sleep mode. You have to have enough power for it to be able to sense when to turh on again.
