when the s2 gives me a 0.8 average DE, does that mean it's completely off..

but you seem to agree that the s2 is quite off on that point ? also with LCD ?
It's impossible to say without a reference instrument to compare it to. The self check error reports indicate how well the display has been made to conform to the target, and how consistent the measurements are. But the absolute accuracy can't really be determined without something independent to compare with.
I'm already VERY happy with the PQ, but the idea of achieving better DE with a i1
> display is starting to grow on me ;) It may be slightly more consistent in its readings, and therefore give a lower self check report, but the visible effect would be hard to predict. Each type of colorimetric instrument will probably have a slightly different calibration for a given type of display, and therefore if compared side by side, may look slightly different. Once again, compared in isolation you may be hard pressed to see a difference due to this cause. And just to correct myself:
The main advantage of the Eye One Pro is that it is going to be more accurate with any spectrum that a colorimeter has been specially
calibrated to. The disadvantage is that it tends to collect less light than a colorimeter, so you really need a longer integration timeto give a repeatable reading.
