Hi, have someone calibrated dell UP2516D for displayCAL (i1 display plus)?
i work with one as reference monitor in a deck link 4k mini monitor and i tried differents configurations, but when i compare it with other monitors, smartphones the contrast and saturation is different… the skin tones is diferent too.
I made this configurations, and created differents luts with differents gammas…
correction: “Spectral: LCD RG Phosphor”Attachments:

Also uniformity compensation destroys contrast when activated in these kind of low cost displays.Regarding backlight if WLED PFS type but with some higher ground in red, like if it was a mix of GB-LED and WLED PFS.
There were CCSS ij colorimeter database but a lot of them where emulated sRGB or AdobeRGB gamut. Ypu’ll have to check one by one using displayCAL gamut plot for CCSS (or by visual inspection of spectral power distribution if you have experience).
UP2716D uses same backlight so if you d not find one, check the other.2021-05-10 at 10:21 #30119I found it on another thread:
1st one, but I do not remember which CCSS was native gamut. Check one by one
2021-05-15 at 22:13 #30228Hi Vincent! Thanks for the answer!
I testing any options but my results are very differents and they dont work…
In interactive display adjustment, I noticed that the whitepoint parameters change according to the correction option I use, and what is more visually correct is the GB-r-LED / RG Phosphor LED family LCD. (when i used for example HP_DreamColor_Z24x_NewPanel.ccss, when i adjust R,G,B whitepoint, indicates correct but visually everything is very magenta.) So, im using GB-r-LED / RG Phosphor LED family LCD.
When i change the whitepoint color temperature 6500 to 6504 the final result changes very much… is very washed…
Uniformity compensation is off. i checked.
I will try a new calibration now, look the configs:
Display: Resolve
Instrument: i1 DisplayPro
Mode: LCD (generic)
white level drift compensation and black level drift compensation is off
Correction: Spectral LCD GB-r-LED/RG Phosphor Led Family

This way i found to check my calibration, is wrong?
2021-05-16 at 0:08 #302312021-05-16 at 1:38 #30234I tried CCSS Dell, DELL UP2516D (i1 Pro 2) 3.3nm, 370-730nm (2021-02-08 13:42:42) and looks better!

If you had read it you’d save time.
2021-05-16 at 21:57 #30244I tried different ccss for up2516D, and almost the result is this:
And when i see in resolve, have a magent cast…
Whats is mean?
(ignore first image, the measurement file, considered only profile information.)

That you keep using the wrong CCSS. Just use a native gamut 3nm CCSS as instructed a week ago. Make sure it is native gamut (gamut plot in CCSS info)
(also make sure you are using the same OSD mode with the same settings in DisplayCAL and Resolve, older dells have separate RGB gain controls for Custom color mode for each input, DP, HDMI… etc)
2021-05-17 at 2:14 #30251where is gamut plot in CCSS info? i cant find..
I tried several ways but I didn’t get good results
2021-05-17 at 9:49 #30253Select correction, then click on “i” information button. 1st info is spectral, click on top and you get gamut info which may be more clear to unexperienced users.
Once white is ok, if you keep gettng white color int when you apply LUT3D in Resolve, choose relative colorimetric in LUT3D creation to preserve the whitepoint you get manually.
2021-05-17 at 16:11 #30254Only one has rec709 gamut coverage, the others are adobeRGB, but this one spectral is very weird
I tried to new calibration with this ccss, but is very green too

Also this is color at the center. Color uniformity issues in those low cost displays may make it look with a color cast in whole screen. Test it, deltaC in uniformity report in displaycal, non correctable unless it has some kind of uniformity report but using it destroys contrast and un that 16D series locks RGB gain controls: white point need to be corrected in GPU LUT for ICC profile or in LUT3D aiming for abs col. intent.
In the end if you take visual whitepoint approach to fix white, remember to DO NOT use abs colorimetric in LUT3D, needs to be relative to preserve that visual whitepoint.
