http://bugzilla.opensuse.org/show_bug.cgi?id=1137778 Bug ID: 1137778 Summary: Enhancement: YaST module that controls HDMI black level (aka colour/qunatization range) Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: x86-64 OS: Other Status: NEW Severity: Enhancement Priority: P5 - None Component: YaST2 Assignee: yast2-maintainers@suse.de Reporter: alexander.shchadilov@gmail.com QA Contact: jsrain@suse.com Found By: --- Blocker: --- "Wrong black levels through HDMI" is an old (and still relevant) issue that affects Windows, Linux and MacOS. An overview of possible workarounds for both Xorg and Wayland can be found here: https://www.brad-x.com/2017/08/07/quick-tip-setting-the-color-space-value-in... It is from 2017, but as far as I know, nothing has changed since then. Just for context, this is an article about Windows (and it has a good illustration of the issue): https://www.howtogeek.com/285277/how-to-avoid-washed-out-colors-when-using-h... I think it would be handy if openSUSE had a YaST module that implements Linux workarounds from the aforementioned blog post (or Wayland workaround only if Xorg feels obsolete). It could have a GUI with toggle presented in YaST Control Center; also system could show a warning ("Colours were configured in a way typical for [PC display|TV]) after previously unknown display device was connected to HDMI and driver chose a mode. Keeping user informed is arguably even more valuable feature than having a way to configure range from YaST. It is hard to notice that anything went wrong if you are not familiar with how a particular display model performs. There are a lot of people who buy a new display, plug it to HDMI and think "It looked better on the shelf, but this is how marketing works". I understand that, generally speaking, it should not have been a software problem from the beginning and hardware manufacturers are to blame - an in-depth discussion: https://www.avsforum.com/forum/26-home-theater-computers/1477460-theory-abou... But this is what we have in stores. -- You are receiving this mail because: You are on the CC list for the bug.
