Dear All, I use the Eizo ColorEdge CE240W as my main monitor. I calibrate it with the Spyder2 and Eizo's ColorNavigator software. After each calibration, ColorNavigator produces a "validation record", which consists of a long list of figures as shown in screen captures, as well as a short "target/result" list. (ColorNavigator also provides options for more detailed validation records, and produces several seemingly different sets of data - for example, CIE1976 or CIE2000, plus something called a "Delta-E" validation result graph.) I understand, generally, that this is supposed to show the variations between the target settings and the actual settings achieved after a calibration. Beyond that, I have no clue how to interpret the validation results/figures/data. I called Eizo technical support and, although they have been very helpful in all other respects, on this one they couldn't provide me with a simple explanation and ended up, basically, saying I need a degree in color management to understand it properly. (I have a couple of degrees in other areas, but, alas, I truly am too dumb for most tech/computer/engineering stuff - sorry!) I don't need a detailed explanation of what it all means - just a rule of thumb to have an idea if anything is seriously off with the calibration and/or the monitor. Put simply: how do I know if the variation between the calibration target and the actual achieved result is big enough to be of concern? Many thanks in advance for any guidance. Cheers!
