Software display calibration

[dire forge]

New to linux, recently converted through Omarchy. So using Arch and Hyprland with a GeForce RTX 3060.

I need to be able to adjust my software contrast, brightness, and gamma. With different settings for three external monitors. Individual RGB values would be great too.

The closest thing I have found to being able to do this is wl-gammactl, but had some issues there. Such as getting it to autostart on boot, and having different settings per monitor.

I could use some recommendations for tools to be able to calibrate each of my monitors.

additionally, autostarting can be done with the exec-once = <command> keyword in hyprland config

also, consider using KDE instead of hyprland, as the latter isn't really made to be beginner friendly

and they have gui settings and everything

Yeah I think I am going to try KDE and see if it has the ability to calibrate my monitors built in. Otherwise I'm probably going to go back to debloated windows. It's a real shame because of how much I'm enjoying Linux. But I absolutely need the ability to calibrate my monitors.

im not sure how you are gonna "calibrate" your monitor, as that would require special equipments because monitors do not know what they look like themselves and therefore cannot adjjust accordingly

but both kde and hyprland support loading color profile files

so if you have one of that you can just apply it

.icc files to be exact

Yeah, using a colorimeter is out of the question right now. What I was doing before was balancing hardware brightness, contrast, and RGB along with software equivalents and using reference images on my iPhone to get the most brightness, contrast and color accurate settings I can across my 3 monitors

if you already did all the calibrations on windows you can just export that as an icc file to use on linux

or if you cant for whatever reason, there are programs for creating icc files on linux
