Hello! First of all, excuse my english, I'm using the google translator. I have tried to calibrate the screen of my lenovo y50 (b156htn03.6) with i1display pro in rec.709 (to be able to make a correct color correction to videos) creating an icc profile to install it in the computer directly (using the longer option) of 11140 images). But after doing the calibration process, I get the option to save the 3d lut but not to install the profile (as if it happened when I calibrate a TV as the second screen). For displaycal to load it, or I have to close it and reopen it or before closing it distill "apply calibration (vcgt)" so that when clicking "install the profile" (on the button next to settings) do it, but it lets me save the 3d lut but it does not install it. The problem is that with either of the two options I get a slightly yellowish image and for example the google windows instead of looking gray (like when the srgb profile iec61966-2.1 is installed -> https://www.dropbox.com/s/fakeb0o13i5uvl4/srgb%20iec61966-2.1.jpg?dl=0 ) look yellowish-green -> https://www.dropbox.com/s/vbfp2j9ptan8kum/rec%20709%20lut.jpg?dl=0 .
From already thank you very much!

  1. Hi,

    using the longer option of 11140 images

    I think that is overkill for a Laptop. Display stability may be an issue. Make sure the Laptop doesn’t dim (power saving) during measurements.

    after doing the calibration process, I get the option to save the 3d lut but not to install the profile

    The install button is context sensitive. On the “display & instrument” tab, it lets you install the profile (only for actual, not virtual display devices), on the 3D LUT tab, it lets you save the 3D LUT.

      no, it’s with the high performance option.

      sorry, you did not understand. the way I keep the profile is in icc, so that the colors look correct even when I play a movie on the computer players, which serve as a reference to see how they have really colored in post.

      How do I make it so that when I install the profile I see rec 709 and not green-yellow as it happens after the new profile is created and installed? I tried with the option to install along with the pre-calibrated profile, as it is marked by default, and with the option to distil it and I can not get the calibration to look correct, as if it happened to me when I calibrate a television as a second screen.

    The software you’re using needs to be ICC color management capable, and the source color space defines what colors should look like. Web browsers should assume sRGB for untagged color data. Note also that the only color managed browser on the market today that works correctly seems to be Firefox (with tweaks to its configuration). Chrome and also to a lesser extent Safari on Mac OS X have bugs that impair their color management capabilities.

    1. The software that I have is windows 8 and use only disclaycal, the rest is all as it comes from the factory. Even so, I only have the problem when calibrating the screen that comes with the laptop; If I calibrate a second screen (a samsung TV) the correct calibration is noted and it works well in all browsers, windows and players. What I need to know is that, how to do the same for the laptop screen; If I do something wrong or I have to configure something specific. I repeat you calibrating a second screen you see everything perfect with the integrated screen no longer, that’s why I do not think it’s due to the windows software, if I understood correctly. Sorry the insistence, I need to calibrate this screen because I moved and I no longer have other screens, I have the laptop just for that reason I need to be well calibrated.

          1. The display output isn’t stable at all. Reduce the number of patches considerably (e.g. use default of 175), enable white level drift compensation and set patch sequence to “maximize lightness difference”. Also, it is crucial to enable calibration – set “Tone curve” on the calibration tab to “Gamma 2.2”.

            Apart from that, the display hardware is a limiting factor – only 57% sRGB coverage is a very low figure, but there’s nothing that can be done about that.
