leaving PC/presentation monitor on?

[shorthair]

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?

If it powers back up when there is a signal then NO it is not completel off.  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.

That would be unnecessary wear then, over time, right?

Not really, only small power circuits are on - high voltage off. You can tell that as when the signal is restored you will hear the high voltage (static) sound. So High Voltage, Horizontal, Vertiacal circuits are powered down.

Nothing detrimental.

In my opinion, it's actually better for the equipment to leave it on than to power it up and down each day.  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...

Thanks, Rick. The next question, sorta spurred from what Bumbles said, is the electricity being used when in sleep mode?

[BobA]

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.

So maybe a couple/few watts, like what is used in the memory for home a/v components I guess. That's what I thought. Thanks.
