Hi,
I am having problems with my new Dell U3225QE in HDR mode. Sometimes the browsers don’t pass the wide gamut tests, but sometimes they do. Gradients in browsers are jaggered.
I updated firmware from Ubuntu live, and noticed that the monitor info popup mentioned 30 bit color when I was in Ubuntu. But when I booted back to Fedora 43 it is always 24 bit.
I’m on Fedora 43, intel video, all latest software from testing updates repositories.
What would that be?
I did some research, and the outcome is just crazy stupid.
With Gnome on Wayland, intel drivers selects the “pipeline” based on what’s on the primary screen (8 bit), which is laptop screen, even if it is closed. But when the laptop is open, by some reason, external monitor wins the pipeline selection and enables 10 bit.
ChatGPT tried hard to explain this nonsense. But this is how works.
With X11 it doesn’t work the same way.
Anyway, even with HDR enabled, and effective 30 bit pipeline (10 bit per color), the gradients in browsers are jagged.
