![]() ![]() ![]() Someone should turn that into a command line option, as it’s useful if you bought a recalibrated one from ChromaPure. You can always dump the observer curves of your i1d3 from Argyll with an ifdef. What’s the uniformity of the screen? Perhaps you’re measuring in an off color patch? ![]() There’s really no possibility of a metameric failure here with that wide filters i1d3 has… unless it’s sending near UV and you’re picking it up. Then there should really be no problem with calibration. If someone else only had this monitor then they would have no way of knowing that the measured D65 looks way too blue compared normal gamut ones. The CCSS file is for the same display model though, and it’s a 1nm spectral sample, I would expect the whitepoint to look the same as a standard gamut LCD, even the OLED TV I have looks the same when at D65, it’s basically only this monitor that it seems I need to calibrate to around 6000k VDT to make it match D65 of those two others. (All temps daylight locus.) On gamut chart it looks dead on, but it’s slightly wrong. It is getting corrected to slightly bluer version due to calibration mismatch, reported as 7000K VCT, but 6500 K CCT. There is a nice matrix profile made by someone, but it produces nonsense numbers, for example VCT of ~6500 K for uncalibrated state (though ~5700 K CCT) where it actually looks pinkish, kind of like whiter Illuminant E. I’m having such an issue with Acer XV273K here, which seems to be PFS type phosphor but not matching any of them exactly. And that’s definitely within manufacturing tolerance of the LEDs. If it’s a sharp CCSS, and it is, a simple 10 nm offset within calibration will ruin matches. I mean, the CCSS is probably correct for the display that was measured. This reply was modified 3 years, 3 months ago by Vincent. P.S: On top of that, of course there is the possibility of observer metameric failure… but that is user related and varies with user so the whole purpose of alternative “numeric” white points on a WLED PFS monitor is a nonsense. use visual white point match for all, choosing one as “reference” Measure all of them choosing the best colorimeter correction for all or a reference device. The whole setting you try to compare is hardly consistent so aiming to “numerically” alternative WP is an error unless you: There is/was a JETI CCSS for that displays, almost a perfect match to “Panasonic VVX**** ccss” (95% P3), so that CCSS works unless manufactured changed backlight model. “standard IPS” monitors whitepoint is unknown unless measured. “standard IPS” monitors unless calibrated to D65 with an accurate device… are not D65. (Note the difference between “numerical” vs “visual/perceptual” where that consumer TV is visually matched to another display that is its reference) Consumer WOLED TVs with “numerical” alternative WP to D65 are just poorly measured TVs in most cases. OLEDs with alternative WPs are RGB OLED not consumer WOLED TVs. ![]()
