    Hi,

    please go to your storage directory (see the ReadMe to find its location) and look for the folder that was created when you got the error (the folder will usually be named “<name of display> #<number> <date> <time> <other parameters>”). If the folder is not in your storage directory, it may also be in a directory named “incomplete” (in the same parent directory that is containing the storage directory). Create a compressed archive (e.g. ZIP) of this folder and attach it. Thanks.

    Hi Florian,

    I have restart the computer and increase the display brightness and it work.. if I have again the problem I will attach here.

    By the way, I have this result for my macbook air 13” (mid 2013):

    complete report at: https://www.dropbox.com/s/nfrx4kphuk0nu2q/Measurement%20Report%203.1.3.1%20%E2%80%94%20Color%20LCD%20%40%200%2C%200%2C%201440×900%20%E2%80%94%202016-06-08%2007-05.html?dl=0

    Can you please tell me what I have to do to get better results ?

    Display & Instrument:
    + Laptop (Gamma 2.2)
    + LCD (Generic)
    + White level drift composition – Active
    + Black level drift composition – Desactive

    Thanks

    That looks fine.

    LCD (Generic)

    I’m pretty sure the macbook has a white LED backlight.

    White level drift composition – Active

    Make sure to disable automatic brightness adjustment of the macbook (System Preferences -> Display).

    I would recommend using the “Auto” testchart setting and disable CIECAM02 gamut mapping (most applications including Mac OS X itself don’t let you choose a rendering intent, so the time spent creating perceptual and saturation tables is basically wasted).

    Hi  Florian,

    I have run other test:

    And I get this:

    Any tips to remove that RED on the 281 ?

    Thanks

    Using the “Report on Uncalibrated Display device” I get this.

    That does what it says, it reports on the display as-is, no calibration active.

    Any tips to remove that RED on the 281 ?

    The error is only slightly above the threshold, I wouldn’t bother.

    Edit: Please don’t cross-post, instead, use a link to the existing post.

    Hi Florian,

    But is anything I can try or do ? Ex: Calibration Speed: Slow ?
    Note: Sorry the cross-post!!

    If you want higher profiling accuracy, you have to increase the amount of patches measured during profiling. But note that your result is already very good, so you may hit a point of diminishing returns.

    Hi Florian,

    I will increase the amount of patches …. I would love to see all report green 😉
    Thanks for the support!

    You really have to disable any and all dynamic brightness and/or contrast adjustment of the screen, and make sure no light is shining directly on it (high levels of ambient light should also be avoided if it’s not static). The calibration got botched because the screen was changing while being measured.

    Whaere is the ReadMe?

    You know I never thought the browser color scheme was so pretty until I calibrated my monitor!  And why do I care about the ICC profile?

    In the “help” menu.

    And why do I care about the ICC profile?

    That’s what allows for correct colors in applications that support ICC color management (e.g. Firefox, Photoshop, GIMP). The 1D calibration can only fix whitepoint and grayscale.

    I’m trying to calibrate BenQ PD3200U display, and getting this error. I tried 3 picture modes this display has: Rec.709, sRGB, Standard, and all end with the error. I’ve attached logs from Standard picture mode.

    You’re driving the display with incorrect output levels and thus severely clipping levels 0-16 and 235-255. Set output levels to limited range (16-235) in your graphics driver control panel.
