Color correction in linux vs windows

post #1 of 4
Thread Starter 
I'm testing linux as an alternative OS for my needs and I'm wondering about color correction in linux. Keep in mind that I have no idea how colors work at the OS level or if it even matters what OS you use.

When I installed different linux distro's I noticed that the monitor wasn't able to differentiate between shades of grey. It all became a white mess.
I had to change the monitor setting "HDMI black level" to get it close to how it looked in Windows 10. The default setting was "low" which worked fine in windows.

Colors also seem to be close, but still different between my current install of Arch linux and Windows 10.

Could this be because Windows applies a profile automatically, or do they interpret sRGB values differently?

Are there any differences between linux and windows if both are:
1. Not color corrected
2. Color corrected

What desktop environment are you using? Gnome, KDE and Cinnamon should have color adjustments in their system settings (As in Windows Control Panel) Or if you have an nvidia gpu you can adjust colors in the nvidia X Server Settings.

If you have a color calibration device you can use DisplayCAL to create a color profile.

Another option is to save your settings in Windows to an ICC file and use DisplayCAL or Gnome color manager to import the profile. There may be other ways to import the profile in the system settings of whatever Desktop environment you are using.

Ur best bet either on windows or linux would be using DisplayCAL as Diffident said above and then make an appropriate icc profile on your monitor.
DisplayCAL wil install the created icc profile prerfectly on windows, on linux u might have to load it with xcalib, at least in my case with xfce.
I added to my startup "xcalib ~/.local/share/icc/22EN33-2015-07-22.icc" in order to be auto loaded every time.

In case u dont have a colorimeter try to loan one from a photographer for a few hours if u know anyone. If u'r really into proper color management,etc and u cant get ur hands on one , many photographers will "rent" u one for a day ,

If u cant get ur hands on one u will have to find pictures from google with all shades of grey/black/white etc and adjust so that u can see all shades. A good starting point would be starting with max contrast and brightness anywhere from 20-40% and adjust from there , preferably only the brightness first. Also dont forget in your monitor to use the "user preset" and not the movies/games/etc. 6500/5500 color temperature or manual/user if it doesnt seem neutral. Google the pictures for monitor calibration and u will find plenty of them
