I've found that new "photo" 4k monitors have an update of DCCS:
http://www.dell.com/support/drivers/us/en/19/DriverDetails/Product/dell-up3214q?driverId=70JPG&osCode=W732&fileId=3298218629&languageCode=en&categoryId=DD
This new version seems to be some kind of customized i1Profiler v1.5.1 (new i1DisplayPro SDK, newer than old DCCS and backwards incompatible... I think). Even it comes with a basic validation for your profiles!!!
It is only found in "Dell UP3214Q Monitor" downloads section of Dell's website.
In its release notes I read:
1. What’s New?
Version 1.5.1.14688:
• Support of the new 24” Dell Display (UP2414Q).
Version 1.5.1:
• Moved Dell UltraSharp Calibration Solution to new UI. (User interface)
• The new UI allows User to create display profiles for non-Dell monitors, can create printer profiles, Scanner profiles, and the ability to perform other related function.
• Support of the new 32” Dell Display (UP3214Q).
2. System Requirements:
Minimum suggested hardware/software requirements:
Supported Languages: English, French, German, Spanish, Italian, Portuguese (Brazil), Japanese, Chinese Simplified, and Chinese Traditional
Supported Dell Displays:
Ultra2413, U2713, U3014H, and UP3214Q
As I understand it, this update allows users to have a non-GBLED-Dell 2nd monitor calibrated and profiled in GPU LUT and "photo" monitors (GBLED + 4k) calibrated in monitor's LUT3D. Am I right?
Questions (I've installed it in a W7x64SP1 virtual machine for inspection):
1-Should an U2413 owner (for example) install this new release?
2-This calibration would be stored in CAL1/CAL2 (internal LUT3D) for U2413/U2713H/U3014?
3-What spectral corrections would be applied fro GB-LED Dells?
In "C:\ProgramData\Dell\Dell UltraSharp Calibration Solution\displayTechTypes.xml" there is no entry for a GB-LED Dell. Since my test is a Virtual Machine my Dell U2413 is not detected and there is not a "combo box" to choose backlight technology.
4-Does an user need to "factory reset" its Dell GB-LED monitor in order to recalibrate it? (in order to reset LUT3D)
5-If question 1= yes and question 2= yes and, question 3 uses (even hardcoded) GBLED spectral correction (last 4 spectral measurements in RG_hosphor.edr), then... what is the sugested procedure to uninstall previous DCCS version and install new one? A XRDDevicesManager driver update is involved in this process...
6-Does this new DCCS use some kind of custom patches for LUT3D calbrations?
Old DCCS took 10 patches for every R,G & B channel plus grey (10+10+10+10=40) in order to measure native gamma and calculate corrections to desired gamma. Some users (like me for example) where experiencing that grey range ("color cast" in some parts of a grey gradient like http://www.lagom.nl/lcd-test/gradient.php , please watch it in a color unmanaged browser like MS Internet Explorer) was sometimes (some calibrations) too high for a LUT3D. These color cast were seen in RGB grey values BETWEEN actual DCCS measures (stored as log files in "C:\Users\<MY USER>\AppData\Roaming\X-Rite\Dell Color Calibration\PrismData.log").
For example,"old" DCCS measures patches for native RGB values of 0,15,31,56,92,128,163,199,224,240,255, most of "color" deviations from grey after calibration are located between RGB greys 42 and 56, and 177 and 198. As individual patches they measure well, <2dE but some are little deviations towards red, and others(177-198) toward green so they are a issue. Well... this calibration is USABLE and pretty good but this hardware can(should) perform better.
These issues are caused because more patches are needed to measure native gamma, twice its number at least and only in their individual R,G,B and grey ramps from 0 to 255. Our i1DisplayPro is pretty fast so no performance is lost for 40 more patches and quality is greatly increased.
What does new DCCS do to read "native gamma response" prior to its correction? Any user with a new Dell 4k monitor has tried this software? To these 4k users, can you copy&paste "PrismData.log" (first 100 lines)?
Chris, can you confirm or send to "lab team" these questions? and if this really works, good job.
