I hope someone can assist me.
I have some knowledge of Displaycal but do struggle with some complex issues.
I have an older Dell U2412M and a newer Dell U2415. I have been using Displaycal for a number of months now.
Both monitors appeared to be the same and I had no issues. I has simply followed a video tutorial.
About a week ago there was a Win 10 update (19041). After installation and reboot a number of my display settings (background etc) and my Spyder X was not recognized in Displaycal. I also noticed the 2 monitors no longer matched.
I proceeded to calibrate and profile both monitors as usual, but could not seem to get a match in whitepoint between new and old monitors. I could not even get them to match up very well when using the visual whitepoint editor.
I then did a few reports and noticed that while the new monitor met the whitepoint tolerances, the old did not with delta E of about 2.5.
Out of desperation I profile again using values of 6500K and gamma 2.2 and changed the profile mode to curves and matrix.
This time I got good results on both monitors and tweaked the whitepoint with visual editor to get a good visual match.
So at this point everything seems? to be Ok but was curious why I had to use a different methodology. My guess is the performance of the old monitor is not sufficient ans could not be compensated.
Any thoughts?
Thanks in advance
