I have 2 monitors, an Asus VS229 (connected via DVI, primary monitor), and an Asus VS228 (connected via HDMI, second display). My videocard is a GTX 970.

In the windows display manager, it shows the VS228 as monitor 1, and the VS229 as monitor 2 and sadly, windows does not offer an option to change this. When booting, the bios screen is shown on the VS229 display, thus the card also considers the VS229 as display 1 before windows is loaded.

Anyway, Windows considers the VS228 as monitor 1, and the VS229 (set as my main display), as monitor 2.

When calibrating the VS229, I noticed that after the process was complete, and the profile installed, the colors were changing on the VS228, and no visible difference was taking place on the VS229.

The logs are a little old, as when I initially ran into this issue, I ended up removing displaycal, and re-installing the colormunky software and making due with its calibration, though it does not do as good of a job as this application.

All in all, the issue was simply the profile for the VS229, kept applying on the VS228 monitor when I attempted to calibrate it using mostly default settings with the exception of using the native white point, and increasing the number of patches.

This was done to a fresh windows install, though I had used this application on an older windows install, and the profiles were applied to the correct displays.

I believe it was also an older version of the software, though I am not sure of the version, but in the zip file, I also included the color profile, and measurement report, and logs that was generated at that time.

I can pull other data from that time if needed, as I have an image of the drive before doing a fresh install.

The OS both times was Windows 7 Ultimate x64

From comparing the files, the main difference that I see is that is lists the display as VS229 #2 instead of VS229 #1  (as it was before the fresh install)

    The order and numbering of the monitors is irrelevant (it’s only meant as an aid for users to visually identify the monitors).

    Make sure the correct profiles are assigned to the correct monitors in Windows color management control panel.

    The numbering is irrelevant and purely informational (see above).

      1. Make sure to use the latest version (3.1.7.2) of the software. In the previous logs, I see you used the 3.1.6 profile loader a few times to reset calibration, and this could overwrite the cached gamma ramps for the first second enumerated display in versions prior to 3.1.7.1.

        1. Thanks for the quick reply,  I cleaned the folders from the old install,  and had all if the old profiles removed.  I then did a fresh install of these display cal software, and am in the process of repeating the same calibration steps thatI took when I originally  encountered the issue. I am also recording the entire process using a separate camera in order to avoid interfering with the calibration process.
