Just a detail that isn't quite right in the article: black is actually the highest power state for LCDs. The backlight draws the same power all the time (for a given brightness setting) but the pixels draw more power when they are black.

Many monitors now have local array dimming to increase contrast. It's probably fair to assume that dimmed backleds lead to decrease power consumption.
