Here are quick verifies for UP2516D DUCCS sRGB loaded into Cal2 against sRGB IEC61966 2.1
- GB-r / RG family ccss
- PFS WLED family ccss
- DELL UP2516D i1 Pro 2 ccss
Happily, things are coming together
I would add… it’s not even close to a GB-LED like U2413 although if an i1d3 is a good match to CIE 1931 2 degree in those long wavelengths it may not matter at all (nothiong to correct on those wavelegths).
This is a: U2413, like the one in “cleaned” CCSS from DisplayCAL:
Orange (1nm resolution)
User data 3nm from an UP2516D … or a UP2716D,…
I suggested that you may try to use the ones available to DUCCS. These are 2 and are bundled with DisplayCAL: RGPhosphor (U2413+others packed together), WLED PFS P3 95% Panasonic etc that was added in DUCCS 1.6. I did not suggest to try that alone but both.
Also if yu want to use DUCCS and validate its results with the same set of rules…
Roger all that, thank you guys
So Vincent was right, I was mosdef making some kind of mistake because I am getting back on track and profiles and verifies are adding up.
As to corrections: Other comments on web say GB-r / RG Phosphor.
I am comparing results from GB-r / RG Phosphor in the DC built-in plus the “Dell UP2516D i1 Pro 2 ccss”…[Read more]
When I ask DIsplayCal to choose (Auto), it chooses none.
When I look in the list, I see a number of options, none of which is obvious choice…
- This is a GB-r panel, so should I use old Dell U2413 GB-r?
- Vincent suggested PFS WLED xx% P3 but there are three specific vendor’s options for HW and gamuts which are not quite what I am…
To be clear, by BAD I mean I run a measurement then verify using same settings, and get wildly bad gray tracking using ccss.
I’m not saying ccss profile is inaccurate, but I can’t get a proper verification using ccss.
What is the logic behind correction Auto, how does it chose?
Ya I didn’t make that mistake, something else is going on
Profile with ccss, verify w ccss, result is bad
Profile with None, verify w None, result good
No mixing and matching
Simple as that
Cross checked DCal-no-ccss with DUCCS: excellent visual agreement.
All signs show probe is working properly.
Next I’ll try a DUCCS built-in LUT cal for…[Read more]
So I ran into a snafu where using the ccss I mentioned before I make a custom profile I can’t get it to verify without a huge defect in grays—see first attach
So I tried going back to correction None, which was working OK last nite except for a glitch in red for factory Adobe RGB verify. I double checked all settings, re-profiled and re-verify. S…[Read more]
OK that really helped, thank you!
Attached are quick reports for UP2516D factory Adobe RGB using 10 year old DTP94 vs brand new i1 Display Pro plus.
DTP94 says Dell is off their claim of 2 dE by about 0.5 in gray tracking.
i1d3pl says Dell is on target with their claim across board +/– 0.1.
This convergence builds confidence.
?And su…[Read more]
Ah k, I am piecing the puzzle together, so ccmx is matrix comp and ccss is spectral compensation. This lets me throw out several matrix DB items in favor of spectral options
Then I see some are named for what mode the display was in during measurement, which suggests the contributor might not understand the relationship between settings and this…[Read more]
Hey @vincent, this is a follow-up to thread about Dell UP2718Q.
I reported factory Adobe RGB tracking results for a UP2516D that meet Dell’s claims but were on edge of tolerance by DisplayCal standards.
To refresh I’ve been using a Monaco Optix XR DTP94 with i1 Pro ccmx this UP2516D display.
It’s been a nagging question as to whether I can t…[Read more]
@rest-of-world Based on my data-points the conclusion is “Use Dell UP out-of-box Adobe RGB and sRGB modes in good health”
Regardless of points about DTP94 instrument, or slight verification report issues, or the relevance of a factory certification, or noise in the photos I supplied, a UP2516D custom calibration side-by-side with the builtin…[Read more]
Ya so that slight gray tracking mismatch is not a big deal
Photoshop, Adobe RGB images
One is factory Adobe RGB reference mode, Adobe RGB display profile CG unity.
The other is native mode, DisplayCal custom GC cal and profile. I tweaked white of this one to agree with Dell’s factory reference white. Again I don’t know if Dell or…[Read more]
What did pro-level Eizo look like in 2005?
Color settings: Gamma and color temp.
Chromaticity completely unspecified.
Reviewer uses extra application to generate an xy gamut plot with coarsely labeled coordinates showing “larger gamut than laptop”. Looks like…[Read more]
Here’s what a task-focused user wants to do:
- Unbox display
- Plug it in
- Set menu to Adobe RGB
- Get to work
Question: Does factory setting correspond reasonably to Adobr RGB?
Well, design is intended to do so! Included QC cert says basics track design.
Hmm, I want to trust, yet I should verify (I sound like Ronald Reagan!)
You don’t have to read between the lines of my previous message to get that CCT absolutely has a meaning of you assume that if left unspecified Duv is within some good tolerance, which may be assumed if not reported.
Any fact that the omission of the tolerance is misused is a somewhat different matter. I mean, consider the report could be in…[Read more]
If this is a repost forgive me, my phone appeared to throw away a whole submission…
Isn’t it appropriate to assume that that CCT measurements unless otherwise specified precisely track Planckian locus? IOW if no duv is supplied, the offset is zero.
Literature broadly suggests tolerance of duv +/– 0.003 as good tracking.
So unless a claim is i…[Read more]
This thread topic is about @charlesss seeking an Adobe RGB alignment for UP2718Q. One way to get that is the out-of-box factory Adobe RGB reference mode.
Dell includes a certificate on UP models claiming 2 dE conformance in Adobe RGB and sRGB. Cert attached.
As the UP2516D is a cousin of the UP2718Q, I think that if I can measure my pair of c…[Read more]
