    Not currently. You can get a view of the neutral response (tone curve) by dragging the accompanying .icm file with the same basename as the 3D LUT into the profile information viewer.

    Hi Florian,

    I’m getting clipping on this older monitor of mine

    But, the measurement looks fine. Not sure what to make of it.

    I’ve tried using 425 patches and High speed,  no difference.

    Your monitor has a small “dead” region above black. Try a low amount of black point correction (e.g. 1%) on the “Calibration” tab.

    No, not really. It does show in the raw measurement data (Y doesn’t increase until around 2.8% RGB).

    How do I see this info in displaycal..

    Also, is there a difference between adjusting the  3dlut’s blackpoint correction vs the correction in clibrations ?

    You can’t. You have to open the measurement .ti3 in a text editor.

    If you want black point correction, you have to apply it via the calibration.

    Hi florian, i just tried out the black point correction @ 1% under calibration, it has not alleviated the issue

    I believe i described the issue incorrectly,   the clipping only happens when the 3dlut is applied,  so the calibration alone is not clipping it..

    Running mpchc w/madvr and no-3dlut,  there’s no clipping.

    I’m not sure if that influence where the error is.

    Scratch that last post.. I didn’t click install profile on the last run.. haha

    The black point correction fixes the clipping .

    Is there a way to specify even smaller percentages?

    For the black point correction rate . the documentation says use a higher rate if there is “too much coloration near black” what does that mean ?

    What is the difference between the percentage  and rate ?

    I think 1% increments really is sufficient.

    The rate controls, well, the rate of the blending to black. Lower rate = more gradual blending, higher rate = more rapid blending.

    sorry to cut the queue.  I wonder why my measurement report didn’t show up the contrast like his report?

    Thanks

    Sorry, I don’t follow. What is your question related to?
