Okay, thanks a lot for your advice, I was just about to buy a new one! But if these temperatures are average and won't harm my hard drive, everything's fine.

There is a difference between Windows sending a black screen signal, and an off signal to the monitor.

In the first case, the monitor consumes about as much power as it will during regular usage (whatever that is).

In the second instance, the monitor is off, in the same state as if the computer had been turned off, using close to zero power. This is recomended by manufacturers over using the front power button (on some monitors even this button won't change power consumption, cutting power altogether is the only way to zero power usage).

How do you know that?

I know. I'm not talking about a crappy black image screensaver of course. I'm talking about the "no-signal". But indeed even a "no-signal" consumes power.

And that was my whole additional point to your previous post; If you leave your computer on for a long time (hours), but you're not using it, you might as well turn your monitor off (as in cut the power all together) as it will consume power, standy or not. Power which is wasted otherwise.

Recommended to save power??? Where did you read that? This is totally wrong... standby mode or not, the moni (or any equipment for that matter) will always consume power.

Or if you mean: let windows blank out the monitor when you don't use it for short time periods instead of using the power button yourself, than that is exactly what I confirmed before.

I know it will consume power, I didn't say it won't, when

The front power button will cause most monitors to cease using power.

However, letting the monitor turn itself off, after the connected computer has been turned off completely, will use very little power, close to none, and this course of usage is recomended by manufacturers including BenQ, LiteON and Samsung, whether leaving you computer on and inattended for an extended period of time, or leaving it off.

Well, in that case I want to see the exact quote/source, as that does not make any sense at all in reference to power consumption and even not in reference to the dureability of the equipment.

They most likely mean it in the context as we both already have said before: constantly powering anything on/off over a short period of time isn't good for any equipment (nothing todo with power consumption in that case either).

Recommending to leave a machine on for a long period of inactivity is the worse thing you can recommend even for a manufacture (and even how low the power consumption might be in standby mode). If you don't use a machine for a long time, you switch it off.

Well, the 2 monitors i have enters standby mode after 5 seconds of no-signal, i was reading the user's manual of one of them and is just as rav0 said:

Indeed, it might use some power but for some reason the monitors turns their system off after a period of inactivity, wich obviously will be for save a lot of energy when not in use.

And another question, barely related to all of this, how much energy uses a 17" monitor (CRT) and how much an LCD? A lot of people told me CRTs uses a very crazy amount of energy, wich is the main reason of high amount of $ in bills

Indeed. But as I said before, to save even more energy it is best to turn the monitor completely off.

It will never be stated or recommended, in any manual, to always keep your monitor powered on (and thus in standby) when you leave your computer unattended for a long period of time.

The word "monitor" does not say anything about the type of monitor)? A lot of people told me CRTs uses a very crazy amount of energy, wich is the main reason of high amount of $ in bills

It very highly depends on type of monitor, manufacture, size of monitor, age of the monitor, etc... etc...

But on average an LCD uses more or less 30% to 50% less power. If a CRT uses 150W/30W, then a LCD uses 60W in active mode and 5W in standby...

Also, the power consumption curve for a CRT increases more rapidly than for an LCD when you look at the size of the monitor. This means the difference between a 21" LCD and a 21"CRT is bigger than between a 17"LCD and a 17" CRT.

WOW, thanks for the info CR

I've attached a page out of the user manual for BonQ FP756ms. (the last point is the important one)

That doesn't meant at all what you've implied though...

It simply means: do not keep the monitor on all the time without blanking it out, if you don't use the computer for a long time when it is on.

Or: if you do not turn of your monitor, always use the computer power management to blank out the monitor (to prevent burning in, to safe at least some power, to extent the life of other components)

It certainly does not mean to keep your monitor powered on all the time, no matter if you use your computer for a longer period or not, no matter if the computer is turned on or not.
