Yes, I thought that this calculator display thing has to do something with the reflective display and refraction. But I didn't know about the polarization of the emissive displays. (I thought it may indicates some UV content on the light or something like that -> imagine some half-technical bunk... :D) And what do you think about the limiting factor? Is it the sampled wavelength range ( the capability of the sensor or the physical UV filter in all ColorMunkis and some i1pros - I don't know yours...), the sampling resolution, the H3 "agressive coating" layer on the panel's surface, the unusual spectrum of the WCG-CCFLs and LEDs (I think you have RGB LEDs for a H-IPS display) combined with the limitations of the standard observers...? Is it the panel technology itself? To be honest, I currently think that this Munki was an absolute waste of money if it can't really calibrate my display. May be the factory calibration drift (after the temperature change, backlit luminance setup in the OSD, etc...) was in the same range where I am now. And ok, I also calibrated the tonal response but it's not far from my target and ColorMunki is not perfect either (mostly if we talk about the shadow details...). If I need to set up the white balance with my eyes, I could keep with the cheap i1LT (which I sold). Because I need to question the accuracy of the gamut measurements as well (if it can't find the WP, they should be drifted as well, I think...)! So, I can't trust in the "affordable but relatively expensive" (- for a home user) instrument. I can't use my other wide-gamut display as a reference for manual WP setup. What should I do? - Sell this display and find one with native sRGB gamut (and may be a different panel technology?) -> Can anyone recommend me a 10+ bit display with 1920x1200 or 2560x1440 resolution, good responsiveness and relatively "viewing angle free" panel which has nearly 100% sRGB gamut coverage without over-saturation? I think you can't. That's why I bought my current display. :) They don't make any good displays with sRGB gamut nowadays. On the other hand, this H-IPS is a real winner in any other ways: It's fast, it's contrast ratio is high enough. - Should I get a small and cheap CRT display to use it as a reference for the manual WP setup? (And use the chromacity coordinaltes from the manufacturer's ICM file for gamut emulation?) - Should I forget about all of these things, set back the factory settings on the display, delete any LUTs and profiles (or live them as they are now), sell the Munki, and live like the usual "blind" users do? :D
