--- Comment #1 from Zamundaaa <xaver.h...@gmail.com> --- The option is, similar to the problem it's supposed to solve, a bit of a mess :( There's a bunch of displays, primarily but not exclusively older TVs, that require their input color values to go from 16 to 235 instead of 0 to 255. That's the "limited" option. The Full option is what it sounds like, it uses the full color from 0 to 255. The Automatic option is where the kernel is using some heuristic in order to "find out" what the display wants. While there is some (rather stale) development at https://gitlab.freedesktop.org/drm/amd/-/issues/476 about this option, currently we sadly don't get any feedback whatsoever on what the kernel is really doing, and the kernels guess isn't all that reliable. The only way we can more or less reliably know what it does is by setting the option explicitly ourselves... but always setting it to "Full" by default would likely result in a broken default state for even more users. I'm not sure on how to present options like this that are far from self explanatory tbh. It's made worse by the fact that we're bound to gain a few more options in the future - color depth, HDR, gamma and maybe even more. Something like an "advanced" page per output with a short description per option could be useful, both for explaining what the things do and for not making the KCM too big and overwhelming. For now maybe a tooltip could help? Some sort of explanation would be useful for VRR and Overscan, too. -- You are receiving this mail because: You are watching all bug changes.
