Why didn’t the calibration/ profiling set the whitepoint to 6500K? For what it’s worth, the measured whitepoint prior to calibration was even higher (6400K). I set the whitepoint to 6500K but the measurement report after was showing a whitepoint of 6300K only (as seen below).Is this a normal behaviour? If not, is it a fault in the monitor, the i1 display pro plus, or something else? After calibration, the measurement report was showing a black level of 0.1076. I repeated it a few more times until I got to 0.1088. After around 10 minutes or so, I measured it again and it showed around 0.2. Whenever I would measure the black level though, the value keeps getting lower. The monitor was already running for more than an hour by the time I started the calibration.I’ve seen several times about monitors having a lower contrast ratio than advertised but is it really possible to have one that is higher? I would assume that these companies would advertise the highest possible contrast ratio for their monitors so it would be impossible to get something higher than that.Ī couple of things to note as well, which might be related. The results generally looked OK but I’m kind of bothered that the reported contrast ratio was 1127:1, while the specs of the monitor states that the static contrast ratio is only 1000:1. If you want to use sRGB gamma instead now there's no need to re-calibrate, just change the gamma in novideo_srgb to sRGB.Long story short, I finally calibrated and profiled my wide-gamut monitor using i1 display pro plus. Your usage of Displa圜AL and novideo_srgb looks correct from those screenshots – run Displa圜AL on the unclamped display, then load the resulting profile exactly like in your novideo_srgb screenshot, enable the clamp and you should be good to go. These are also (effectively) being used by novideo_srgb now with the ICC profile selected, along with the VCGT and TRC curves. The highlighted values in that Displa圜AL screenshot are the actual measured ones, which are accurate (assuming your colorimeter is not broken). That and the additional saturation you're seeing now is due to the EDID values being inaccurate. Also, there are 3 decimal places in the tool, while Displa圜AL has 4. Information about the calibration of the Apple Studio Display. Please note that values shown in Use EDID primaries setting are quite different from the ones provided by Displa圜AL. What should I start with? Displa圜AL calibration on an unclamped monitor? I think in theory enabling the sRGB mode in your monitor shouldn't result in any worse results as long as it doesn't reduce the sRGB coverage (which is a non-trivial assumption), and I don't see how it could give you any better results. If you do care about the exact black point, I believe you should change "Profile type" to "Curves + matrix" (or, if "Tone curve" is not set to "As measured", "Single curve + matrix" might give you better results) and make sure that "Black point compensation" is disabled. I find it hard to believe that I have 2 specimens with better than usual. Also, my other monitor rated as 1000:1 is reported as 1250:1. No automatic/ dynamic Brightness or Contrast adjustment on. Either one will be fine, though if we were to. I have tried several times to measure it. There are several different colorimeter options on the market, the two most popular are the X-Rite i1Display series and the Datacolor Spyder series. Then just load the ICC profile into novideo_srgb, enable gamma calibration and select sRGB/2.2 gamma there, and that's what your screen will end up being calibrated to (feel free to verify this with Displa圜AL's verification tab, and make sure that "Use simulation profile as display profile" is checked). My monitor rated for 3000:1 is being reported as 5100+:1 in the Displa圜AL report. for accurate BT.1886 tracking, you should be perfectly fine by just calibrating with Displa圜AL's default sRGB settings, optionally with a different white point and/or gamma target (or setting gamma to "as measured" should also be fine). If you don't care about the exact black point e.g. means that it shouldn't really matter which gamma you actually calibrate to. However, you can think of it like doing the work that color management would normally do in some program, which e.g. To be honest, I'm not entirely sure myself as to what options you'd ideally use in Displa圜AL to achieve the best possible color accuracy with this tool.
