    I’m trying to calibrate my 3 monitors:

    • LG 27GN88A-B (10bit, P3 94%)
    • BenQ PD2700Q (10bit, AdobeRGB 75%)
    • Wacom Cintiq 16 (8bit, sRGB 99%)

    BenQ and Cintiq monitor match in colors perfectly, however LG has differences in red colours. Yellow on BenQ and Cintiq is more orange on LG. Orange on Benq and Cintiq is more red on LG. Any idea, what could be wrong in settings? Or is it natural for panel that has P3 coverage higher than other monitors? Thanks.

    You are using them non color managed. Calibration “does not match colors”. Can match white & brightness.

    Then you rely on a profile (display description, created by measurement) and a color managed app to COLOR MANAGE all in gamut colors given a certain image in some colorspace.

    Use it color managed (photoshop), or map all to a known common colorspace to use non color managed (games) like sRGB with tools like DWMLUT.

    Read some tutorial about color management. It may solve most of your questions.

    I’m able to have same white and brightness in all monitors. Well… By eye white looks same. Also darks and gray looks same. Only reds are slightly different on LG.

    For reference I’m preview some of my photographs in Photoshop. For test, when I assign created ICC for Cintiq, it looks more yellow on LG. When I assign ICC for LG, it looks more orange on Cintiq. I think there is difference in correction profiles – I use:

    • LCD PFS Phosphor WLED IPS. 94% P3 (Pana…) for LG monitor (which has P3 around 94% according to measurements after calibration)
    • community matrix profile for Cintiq 16 (i1 Pro)
    • LCD White LED Family (AC, LG, Samsung) for BenQ

    Or maybe I’m completely lost in color management. For example when I set created ICC in Win11 as default and then create a new profile, does DisplayCAL remove that ICC during calibration? Thanks.

    Which tutorial about color management do you recommend? Or maybe fundamental question is… Can I have same looking colors in different panels with different bit depth and color gammut?

    Photoshop reads display profile on app startup, if you change it… Phoptoshop must reboot. Also image test should have a smaller color space (sRGB) with all in gamut colors for all displays, and no display profile shluld be assigned to image.

    It removes VCGT from GPU whgoch is the only think that matters. Desktop is not color managed.

    Free and for starters you have some videos from andrew rodney, digital dog.

    “Also image test should have a smaller color space (sRGB) with all in gamut colors for all displays”, if that holds and profiles are accurate and we skip rounding errors (B&W banding & coloration) you should get a match or a close one (observer metameric failure)
