    Hello,

    total noob, thank you all in advance for your patience.
    I have an old Spyder3 as well as a brand new SpyderX. Both work within DisplayCAL, but both give me the same strange measurements right at the start in the Interactive Display Adjustment window. The color patches look fine, neutral grey, and white. But the sliders are way off center (with the exception of brightness). Trying to adjust monitor colors is almost impossible and would make no sense.
    Any nudge in the right direction would be much appreciated.

    I actually did manage to get all sliders centered by simply reducing the R level in my monitors RGB adjustment to 73%.  G and B are at 100%. This way the Interactive Adjustment Window sliders are all centered, with only brightness slightly reduced.  But my screen now has a distinct baby-blue tint. Running the whole calibration process does of course not change this.

    With this newly created ICC profile loaded I can get a perfect looking screen -as long as I go back into my monitor hardware adjustments and put the R slider back to 100% (where it should be).

    What’s up with that???

    You had a paperweight (Spyder3) and bought another paperweight (spyderX), that’s the reason.

    Make sure you are using the proper measurement mode/correction for your display type, but since these are generic it’s accuracy is far from granted.

    You can try to return it and get an i1d3 from Xrite,

    or rent an spectrophotometer to get a custom matrix correction for your device and your display,

    or use ypur spyderx with visual whitepoint editor in DisplayCAL. If you do this you should not create LUT3D with absolute colorimetric to D65 colorspaces.
