James, I had not come across that method in all my internet searches and gave it a try. Unfortunately, a warning message pops up at the beginning basically saying the process will create a profile that will likely be a poor fit for a wide gamut display. I went ahead and tried the process but didn’t get great results.
I am happy to report that I was able to get the display pretty well calibrated using info from various internet searches and my previous failures. In case it might help someone else reading this, here is what I did:
First, I disabled the Dell Premiere Color application. Next, I used the SpyderX Elite colorimeter. This worked much better than the ColorMunki I used previously, for whatever reason. This got the colors closer than I had before, but they were still over saturated. The final step was going into the Intel Graphics Control Panel where I reduced the saturation and changed the color gamut from vivid to neutral.
I haven’t had time to test the calibration extensively, but my limited testing so far shows it to be pretty good. Definitely a huge improvement.
