Does IPS LED really use so little power?

Says the usage is 27 watts... I currently use a Dell 2707 which uses close to 90watts. I have another 19inch Viewsonic which uses ~13w (probably the most energy efficient 19" LED I know)


I've been searching for a new energy efficient monitor for awhile and I find it hard to believe that a 25inch ULTRA WIDE uses just 27 watts since most 25-30" ones I've checked use minimum 60-70w.

The 34" uses just 41w... wow

Is this actual usage? or some gimmick with all contrast/brightness to low lol

That's a slightly smaller monitor, which will reduce power draw a fair bit.

Often, especially on newer monitors with efficiency targets, the power draw is measured when the brightness is turned down fairly low - if you have the monitor bright, you'll use more than spec.

Depending on what you're measuring your monitor with, it may be over-reading. Cheap kill-a-watt devices are notoriously bad on loads with poor power factor.

But yes, monitors have come a long way. LED is only part of this; the electronics now use far less power too.

I have 24 inch TN panel with 144 Hz, uses around 30 watts. So IPS doesn't seem all that power-efficient in comparison.

Yeah, IPS doesn't make much of a difference. It's more the display driver and the backlight.

That display is an inch bigger, though. It's definitely using a fair bit less per square inch than your display.
