The problem is with the contrast which is then very low (110:1), and my blacks are greys. I can't comment on how DDC mode works in i1 Profiler internally as I don't know, but I can certainly testify that it doesn't work for me either :) How does it work in this case to compensate the screen parameters and provide the desired white point temperature and luminance ? I also tried Automatic Display Control -or DDC- mode supposed to automatically adjust the Display's OSD values, but it didn't seemed to work. BONUS : is it possible to compare my displays gamut between them and against some references ? how to choose the "best" profile because in all my tests I got visually different results, how to be sure everything is OK ? should profiles created under windows work with ubuntu ? none of the softwares asked me to adjust the contrast level in my display's OSD, is it done at the OS's level through diplay profiles ? what is a "good" value of contrast given a white level of 100cd/m^2 ? Does it make sense to load profiles created under windows in ubuntu ? 1 DispcalGUI calibration and characterisation : I think it is visually quite different from what i get under windows, but it is quite difficult to compare, so i'm not very sure. I first loaded the profiles created under windows with i1profiler in my ubuntu gnome OS ( "Colour" menu in system preferences, seems to be gnome color manager). I also run ubuntu gnome and would like to have my display well calibrated and characterized in both OS. With interactive mode on, I had to readjust the OSD sliders of my display to get the right white point level and temperature, why ?Ĭontrast is still low, results seems to be slightly better than with i1profiler. Pretty much the same process as before, I chose white point at 100cd/m^k, left black level "as measured" (should i try setting a very low value to get higher contrasts ?). Which is quite higher than what was set and validated with i1profiler (the calibration done with i1profiler isn't valid anymore ?) 5 DispcalGUI calibration and characterisation : I did a measurment report of the profile created with i1Profiler (which I had to save in ICC version 2, otherwise dispcalGUI could'nt read it), which you can find here : (save as html file and open in a web browser). It seems good, not very fast but nice to use, and gives very detailed reports (that I really dont fully understand!) 4 DispcalGUI report of i1profiler profile Is it a Good/sufficient contrast ? I can't get more, whereas on my laptop display I get something like 600:1 with the same white point luminance.īeing quite disappointed with this low contrast, and wanting to compare my two displays, and their gamut against some references, I tried DispcalGUI under windows. After tweaking a bit and setting gamma to "OFF" in the OSD menu of my display, I got better contrasts of around 260:1. Went OK 3- Report, quality measurements :Īll Delta E were pretty good (I didn't save the report). How does it work in this case to compensate the screen parameters and provide the desired white point temperature and luminance ? 2- i1 Profiler Characterisation : I calibrated to 100cd/m^2, 6000k and "native" contrast (from what I understand, it is set to maximum), adjusting brightness and RGB valus in my display's OSD menu, thanks to some interactive mode of the software doing measures in realtime. I First tried to calibrate and characterize my monitor under windows using X-rite's software coming with the i1DisplayPro (i1profiler). I'm trying to calibrate my monitor (HP 23xi) with a colormunki i1 Display Pro.īeing quite new to display calibration and characterization, i'm facing some problems and having many questions.
