Question:

Does an LCD monitor consume more elecrticity than a CPU?

Im asking this because i wanna know if turning off my monitor can lengthen the BATTERY TIME of the UPS. I also want to know about surge protection.

Answer:

Compared to the system? Way less. Compared to the actual CPU? It is going to depend on the CPU and the size of the monitor. Even the big LCD monitors are pretty low power, a 22 is 40 to 50 watts. Way less than the system or a CRT. Hitting the power switch on an LCD generally does not actually turn it truly off.* It puts it into a standby mode, which will probably be the same power draw as if you let the computer put it into power management. Probably less than 3 Watts. Generally it is a good idea to turn off the monitor when it is not being used, or enable power management to send it to sleep. LCDs do not suffer from Phosphor burn like CRTs, but you are using up the life of the backlight. While 40 watts is not much, it is another 40 watts your AC unit does not have to pump out of the house. * look at the power switch on any equipment. There is a symbol there made up of a line and a circle. If the circle fully encloses the line then the switch cuts all power to the equipment. If the line cuts though the top of the circle then the switch just puts it into a standby state.

In most cases, the Monitor will consume less energy than the Computer (CPU doesn't mean Computer). Turning off the Monitor will lengthen the life of the UPS no matter how much power it does or does not consume.

I do not believe so, however turning the monitor off wouldn't hurt it. From what I understand LCD monitors are very low power consumption. Most UPS units have built in surge protection, and just as long as you have at least a middle of the line surge protector or UPS, you shouldn't have anything to worry about power surges. Plus most of the surge protection components that you buy, they provide certain levels of insurance in case of the surge protector failing and damaging equipment.

At the same time, turning your monitor on and off can damage it. Things only like to be turned off and on so many times. Therefore if your looking to save any money, you might take a hit to the wallet when your monitor dies.

depends, the newest core2's and x2's are much more efficient than the last generation of CPU's and use less power than most monitors if you have like a p4 or a socket 939 x2 it will pull more power than a monitor. yes, if you turn off your monitor, your computer will run longer on the ups.
