icc file above set as “Display Profile”… but what I have instead is “system display profile” which to me sounds the same that I have set globally in Ubuntu prefs?įollowing the docs, this is what I have running darktable-cmstest: (base) $. In DT, it’s important to use the correct monitor profile for the display profile.Īlright, so that means that both in lightable: In dt prefs/image processing I have not checked “always use LittleCMS 2 to apply output color profile”. Now the white level is straightforward (I set brightness using the physical buttons of my monitor to 34 to match the 120 cd/m2 which I understand is a ‘standard’), while for the whitepoint/color temperature I need to fiddle with my monitor which means that in here, instead of choosing “Adobe RGB” in Color Mode: The information here are also a bit confusing for me (1D LUT?), what I sort of understand is that in this way the colorimeter helps me set the appropriate starting points for my monitor w/regards to brightness and rgb colors, using this tool: Calibration speed is set to high, I don’t see any difference setting this to low. Here I check “Interactive display adjustment” whitepoint, white level are set “as measured”, while tone curve is “Gamma 2.2”. In the meantime, I will skip over this problem, pretending it doesn’t exist. What? I don’t have windows! Can’t run Palette Master? What does it even mean “use hardware calibration”? Can’t I calibrate my Benq SW2700 with Displa圜AL? You need to use hardware calibration with the BenQ calibration (Palette Master Element) tool and a colorimeter with this screen. Another discussion about internal monitor calibration didnt make things any clearer. Then, I have understood that maybe this monitor has a “hardware calibration” which makes things even more complicated than they are I have read this discussion here on the forum, featuring an old friend of us dealing with a similar monitor and could not come up with a final solution. The only thing here is to choose a colorimeter correction for my colormunki, I have found this old thread on the Displa圜AL forum where attached a “correction file” to be used for this Benq SW2700, so I use this. All of this on Linux (Ubuntu 21.04), using r-darktable / dt 4.0. I decided this time to describe what I do and perhaps someone in this community will tell me on what is right or wrong.ĭetails first: I’m calibrating a Benq SW2700P monitor with the Displa圜al-p圓 fork by and an XRite Colormunki Display (bought in 2013, no longer produced). I’m trying to keep it simple (so things like gamma 2.2, 6500K, 120 cd/m2 etc, for those who already know these details) I perform the calibration in the evening, with the usual light that I have, no other variables. Each time I decide to be brave and calibrate my screens I always end up with more doubts than before (not to mention the feeling of being immensely stupid).
