Ulco, is that measured power usage (30w), for example with a plugin power meter on your side? Or just what you understood the specs to be? According to the manual the Eizo you have uses "60W or less" (when USB and speakers are *not* in use). It does not have an Energy Star energy use number, which is mostly what I am finding on newer displays, so it's hard to compare. It has a "typical" usage of 19W, which may be when energy-saving tech is in use (which usually reduces brightness of the display, for example).
And of course if you are upgrading to a 32" display from 27", it is quite possible (though perhaps not inevitable, with newer tech?) that power consumption will go up. I will try to add power consumption numbers to my spreadsheet. Though they may not be directly comparable to what you have.
