You can install the propietary AMD graphics too, but you must do a Timeshift backup first, incase things go south.
The hopefully the Catalyst Control panel will have an RGB setting.

Thanks for help, but it does not change antything in my screen. I mean colors are still washed out. And i will prefer open source drivers so I dont change it.
I tried this command:
 xrandr --output <HDMI> --set "Broadcast RGB" "Full"
 but have an error.
I tried gnome-color-manager but it shows only Color Profile Viewer.

I dont have any ideas more how to fix it :/

The Broadcast RGB property is for Intel graphics cards. https://askubuntu.com/questions/883988/xrandr-how-to-find-the-correct-rgb-full-spectrum-output-command-for-my-system (https://askubuntu.com/questions/883988/xrandr-how-to-find-the-correct-rgb-full-spectrum-output-command-for-my-system) Make sure your monitor is correctly set. See second to last post.
