I have rather a strange problem: I have a wide gamut screen BenQ SW240. I am hardware-calibrating it with the BenQ software Palette Master Element on Windows 10. After that, I profile it with Displaycal on Debian Bullseye. I have this screen since a little more than 6 months now, so far I did not have any problems with it.
However, today, after hardware calibration where I set white level to 120 cd, I set Displaycal to 120 cd as well so the interactive tool measures the brightness, just to check. Actually I almost always do/did this. But today Displaycal said twice that brightness was only 100 cd. So I performed hardware calibration again. But the result is the same. So what is going on here? Why is my screen darker on Linux than on Windows?
Well, I don’t think there is a link to the fact that I have a new laptop with dual graphics (Nvidia+Intel), is there? On Linux, I use Bumblebee. Anyway, this was the first time that I calibrated my screen with my new laptop.
Thanks in advance and regards
