I have a brand new Sager NP6855 Windows 10 Pro v1909 laptop with an Intel i7-9750H CPU that has integrated Intel UHD 630 Graphics. An external Viewsoinic 1920 x 1080 monitor is connected via HDMI to the laptop. I also have an older Eye-One colorimeter that I am using with X-Rite's i1-Match 3.6.2 software for Windows PCs. This software was released in 2009 and works on Windows 10 without any problems.
I have been doing color management for over 8 years and I understand the topic very well. I use Windows 10's control panel Color Management app to assign ICC profiles to the laptop's monitor and to the external monitor. I make these ICC profile assignments with the laptop video in the Extend display setting. I can see both ICC profiles, they are assigned to the correct displays, and everything works as expected.
As soon as I change the video display setting to either "Second screen only" or "PC screen only" Windows 10 thinks that the external monitor is Display #1 and assigns the Display #1 ICC profile to the external monitor. The problem is that Display #1 is the laptop monitor, not the external monitor. When I launch Settings> System> Display and click on "Identify," the external monitor is identified as Display #2, which is correct. However, when I launch the control panel Color Management app and click "Identify monitors" the external monitor is identified as Display #1. I believe that because the control panel Color Management app reports the external monitor as Display #1 that that's the reason that the laptop monitor's ICC profile is being assigned to the external monitor, which is Display #2. This prevents me from using the correct ICC profile on the external monitor, which is where I do 99% of my work.
Has anyone seen this problem? If so, what did you do to fix it? I've read that Microsoft released KB4505903 to fix some of these issues prior to the release of v1909. According to articles I've read, the fixes offered by KB4505903 are supposed to be present in v1909, therefore I haven't downloaded and applied KB4505903. Is there a Microsoft fix for this problem or maybe a third party app that takes ICC profile management completely away from Windows 10 (which I would be THRILLED to use!).
Thanks In Advance For Your Help!
