Got 2nd unit and am pleased to say it's in keeping with the first. Some new points about these Dells: There is a "Uniformity Compensation" function and it really works. Implications here are that Uniformity Compensation (UC) mode requires use of a "calibrated" mode, and you are forced to disable UC if you want to do a custom color temp (anything other than 6500) either via a non-ICC-mode preset, or via custom gain/bias. Which leads to a theory about how it works: Panel zone variances must be measured at the factory and storied with the built-in cal data? (If so, it suggests that in principle local measurements could be uploaded into the device in a service mode? And that Dell's Xrite solution can maybe do this? Idk, but fun to think about. (In world of video, is device LUT loading standardized, open or proprietary?) Frustrating because now there is another tradeoff. &^%$^& technology! To give you a sense of what I'm seeing I've added some screen grabs taken with an iPhone, which tends to exaggerate panel / color aberrations. https://drive.google.com/open?id=1DSpUzIAgxsiG8qi8FKr2uJ5_P4MNmTKu These are side-by-sides after running DisplayCal in 6500K mode with UC enabled. I chose this color mode to get as much gamut available as possible alongside UC benefits. In this mode there's slightly worse whitepoint and gray tracking agreement between units as compared to Adobe RGB mode. TRC appears to be native and custom cal is wanted. The measured gamut is also slightly smaller than pure native mode (but total native reqs disabling UC). I wonder here if out of box best cal soaks up a bit of native gamut to cover population variances? IOW trade-off UC and out-of-box color temp tracking to get a better white/black pre-cal and full primaries for custom profile? It's the user's call... When put in "Adobe RGB" mode, these two displays agree side-by-side as good as my custom cal. No trouble believing they hit < 2dE across board. My gestalt at this time is that a designer who hopes to just unbox, set mode and work appears to get what he needs. I may—or may not—take the time to measure and evaluate the ICC presets. Will post if I do. I'm still climbing steep learning curve for these tools. And I'm caught because I'm not sure how much I can trust this DTP94 in my setup. As I play with DisplayCal the repeatability (or lack of it) keeps me guessing. For example, I just found new instrument modes and compensation data are available for download in DisplayCal since I last checked a few months ago, which is great! But adds to confusion. Need a more modern puck. For now my choice is to run these as described above, enable UC, let DisplayCal set whitepoint and target sRGB. This appears to get me to 95% Display P3 and 98% Adobe, with an sRGB TRC for default and UC enabled. It's a compromise that looks good. /wire
