Buying an LCD Display
I decided I wanted a 24” display, so i did a little searching.
I settled on the HP ZR24w, as it was an IPS panel with good colors and viewing angles (IPS panel), had very little input lag, could rotate for 16:10 or 10:16 use, and wasn’t ridiculously priced like most IPS panels.
on HP’s page they are boasting a lot of energy saving stuff like an 85% power supply. But forgive me for not really trusting their energy-efficient marketing, so I started comparing some LCD power consumption and found some striking differences. Take a look at the little table I constructed:
other sources:
What a wide range of power consumption, even at the same brightness. There are no sanely-priced efficient IPS-panel 24-inch displays. On this data it seems LEDs use less energy (no surprise), but maybe IPS panels need more power than tn? I say that because the apple display is LED and IPS and still guzzles watts (oddly even more than the dell IPS ccfl display).
