looks much, much better now!!
does it also look better visually?
A smooth gradient black to white in Photoshop looks good, i.e. shows no banding?
Did you create a LUT profile or is this just the result of my advices WRT to black calibration etc. ?
Now, it will get even better!
The blacks still look off way too much.
What black level did you set as target?
I simply redid a calibration/profiling with SpectraViewII applying all the advices. A few major differences to my prior tries with the PA241W:
- I warmed up the puck (I wanted to believe that, when placed on the screen right before the calibration/profiling, and the profiling being very quick, that there was no need to warm the puck up).
- I used the DTP94b instead of the NEC MDSVSENSOR, NEC's custom mated i1d2 (I resisted this replacement because I paid so much and had so much trouble to get this NEC puck over from America. And it is supposed to be better!)
- In the preferences I checked "Avarage low luminance measurements" ("Improves the accuracy of low luminance measurements by taking several measurements and averaging them."
- I set 52 calibration and profile steps instead of 32.
- I changed the calibration priority from "maximize contrast ratio" to "Best grayscale color tracking" (That was a winner I think?!)
- I used the option "extended luminance stabilization time"
- all other auto's are off
I can't see no banding on a gradient.
The test images show the same kind of difference to the print. The screen is a little bit too bright and has a yellow color cast.
As Black Level I choose "Monitor Default", that's around 450.
I just validated the calibration again, and again and again. This time with the NEC puck, and things look like this:
White point Delta E: 2.95, 3.32, 3.12, 3.79
Maximum Grayscale Delta E: 2.95, 3.32, 3.12, 3.79
Average Grayscale Delta E: 2.19, 2.67, 2.55, 2.89
I have a third colorimeter, a regular i1D2. Here is the validation:
White point Delta E: 8.28, 7.64
Maximum Grayscale Delta E: 8.28, 7.64
Average Grayscale Delta E: 6.63, 6.17
New validation with DTP94b:
White point Delta E: 0.29
Maximum Grayscale Delta E: 1.09
Average Grayscale Delta E: 0.65
So I did a new calibration with the NEC puck, and Delta E is at an average 0.86 and a max 2.86 (including dark values). DTP94b validation is White Point DeltaE:2.87, Max Grayscale DeltaE:2.87, Average Grayscale DeltaE: 2.04
To be honest, for soft proofing purposes, or any critical color work that is, this screen is not usable. Mainly because of the yellow cast. As I said, prints, on different printers and with different profiles, consistently come out darker and blueish, magenta.
