- Unless “as measured” is chosen for the white point in the Calibration menu, the CCT is not displayed during the initial measurement; only the CIE co-ordinates and dE are shown. Would it be possible to have the CCT displayed for all white point selections? I use the CIE co-ordinates for accuracy but a CCT reading would make it easier to get…
From that screenshot
- Multimedia P3 displays (PC monitors with P3, non quantum dot)
- Graphics carts monitors like newer NECs or newer Eizo CGs
- Macs with P3 screens. It does not matter if they are macbooks or imacs, if they are P3, use this one.
3 is very close to 1, just a small difference in green.
PA279Q is a GB-LED so generic GB-LED bundled with DisplayCAL (U2413). Acer looks like a norma TN LED monitor so Generic W LED or if there is a CCSS uploaded by cmminity for that Acer use it.
Try a cooler white point (but “white”) first.
Thanks, @vincent !
Just a couple of follow-ups though.
1. If I want to stick with the native WP, does this mean that I just leave the WP setting to “as measured” AND don’t adjust the monitor gains when the interactive display adjustment is shown? Are there any drawbacks when doing this, or will I still have good results?
There is a severe…[Read more]
Eizo EXs are some kind of rebranded Spyders. Up to 5 and including it they have a bad reputation. If using default corrections available for them white does not looke white then:
a) try to borrow or rent an spectrophotometer, create a custom matrix correction for each of your displays and your EX.
b) try to borrow or rent an i1d3 using default…[Read more]
Max contrast ratio is at native whitepoint. If you correct WP in GPU or using monitor OSD you are limiting one or more channel max output, but since you are using a backlit panel the light leaked in black is the same… hence contrast drops the further you go from native whitepopint.
GB-LED, or more specific low cost GB-LED tend to hae a native…[Read more]
So the RGB value R=20, G=20, B=20 in the image must became a RGB value of R=20, G=21, B=19 for instance, at the graphics card output (after passing the CMM). So that a neutral gray is actually displayed.
In the same way as high bitdepth GPU LUT + dithering is needed for smooth GPU calibration, color management engines need something “more” than…[Read more]
Well, unfortunately my NEC P221W is the kind of display that obviously needs more measurements in the darks. The results are not really bad, but they are not perfect also. Although I already use 1148 patches for the profiling, which is quite a lot I think, I will have to experiment a bit. Maybe with custom made test charts. Moreover I will think…
GPU LUT may have 16 or 14 or 12 or 10bit to store (even truncated to 14-12-10bits) VCGT contents… BUT you have to output that correction to display in a proper way.
If GPU link to display is limited to 8bit because monitor does not accept 10bit/channel input or because you use DVI that GPU LUT output is giong to truncate corrected values to…[Read more]
And a extremely useless HW calibration software.
Download it, install (better do it in a virtual machine), take a look. Extremely set of limited presets, no suitable corrections for i1d3. Asus software is the worst among these low cost widegamut models.
Why do you need a widegamut display?
Video editing? Need P3 or just…[Read more]
Florian is right, no use for CCT values in an uniformity report. CCT give you a hint about blue-yellow axis deviation in different places of screen, buy you get no information about the extremely common green-magenta tints across screen.
dE (“total error”, default test) is linked in DisplayCAL to an ISO validation. A PASS/NOT PASS test which is…[Read more]
This lack of success in achieving a good match between the displays seems odd to me. Both claim to be capable of ~100% sRGB… and in practice, people (photographers and others) do work with both laptops and external displays interchangeably.
Also this is a misconception.
Coverage % value of some colorspace it’s just an intersection ratio o…[Read more]
Would appreciate your help.
I have an Asus UX580GD laptop (100% sRGB, IPS display), and a Dell U2417H (99% sRGB, IPS display) as my main screen. My colorimeter is Spyder 3.
Not the most suitable measurement device for this task, as you may know.
The displays match in color (that’s actually quite impressive – credit to DisplayCal), but the…
Do you own this one?
For DisplayCAL it’s an i1dispalypro, so you can:
-find a WLED sRGB-like CCSS from community that matches something like “imac 2011”
-use standard WLED correction (White led IPS etc…) bundled with DisplayCAL. This one is the same you have been using with Basiccolor (it’s “standard” WLED sRGB-like spectral sample from X…[Read more]
Also if you meant “i1display pro” with your word “i1display” you may want to look for a custom spectral correction (.CCSS file) in displayCAL database for imacs 2011 (if any).
Imac widegamut from this years were not LED (WGCCFL like Dell U711), so if it is LED it’s likely to be White LED sRGB. If you do not find customized CCSS use generic White…[Read more]
1- the proper way to measure a display like PA246 (widegamut ccfl) with a colorimeter from i1d3 family like yours is to use WG CCFL correction.
2- if your display+card does not support 10bpc then you may suffer some GPU LUT truncation errors that result in banding. Visual check with a smooth black to white gradient in MS Paint, like lagom test…[Read more]
but choose D65 as whitepoint target
If you plan to stay with a Spyder5 I would trust spectro readings as the only reference so CCMX @3nm for your measurements with your colorimeter.
But it will be nice if you make CCSS and upload that CCSS to community so other people can use that “portable” correction for those display models.
Also you must know that some laser projectors (blue /…[Read more]
Here’s the latest one that was just created. Monitor is an ASUS PA246, and video card is an RTX 2080.
All seems OK for a Widegamut CCFL calibrated & profiled in native gamut mode (maybe Standard or Custom OSD modes, IDNK exact names).
Make sure you are using DisplayPort and you configured 10bpc in nvidia panel to avoid some issues like banding c…[Read more]
