Q. Can anyone shed some light? I'm stuck between buying the benq xl 2410 or asus vg236he. Only difference is asus is lcd and benqis led. Is it worth paying $400 for the led instead of the $328 lcd? What's the difference?
A. The only difference between an LCD and LED display is the backlight. In ordinary LCD displays, some sort of luminescent lamps are used, whereas LED displays use LED's (light-emitting diodes). The LED's consume less power (and therefore emit less heat), they also usually produce steadier light. The LED's also typically live longer than luminescent lamps.
Since LED displays consume less power and live longer, they are more economical in a long range. But given the price difference, it's unclear whether you'll get return on your investment any time soon (if at all).
Since the light characteristics differ quite a lot between different luminescent lamps and even more so between any of them and LED's, I'd suggest looking at the displays in question before buying them - just to make sure you like the colors.

What type of computers use more energy?
Q. Dual Core, Pentium D, Intel vs AMD, Core2 Duo? How do we know from the computer system that it uses more energy?
Like when the computer is turned on, off, and standby, how do we know what type computer uses more or less energy?

A. The processor is only one part of a computer system power consumption. Look for:
Energy Star 4 or 5 computers.
80 Plus efficient power supplies.
Computer Power Management turned on by default in the BIOS and operating system.
LED LCD Monitors
Greener hard drive or solid state drives.
Try to avoid the fastest graphics cards.
Turn off the computers and peripherals at the wall power point to eliminate standby power use.
Even within each class of processor listed there are speed/power levels.
Quad core AMD Phenon processors use about the same energy as Dual Core Intel processors.
