Notebook screen the look is "matte" in KDE

[Leandro]

Hi, feedback:
In general, on the notebook screen, the look is "matte", smoke in the images, videos, games, on the desktop, etc., especially when the screen brightness increases.
When compared to Ubuntu with gnome, windows 11, it has greater clarity, stronger colors, etc.
In Kubuntu I didn't find the option to increase the sharpness, to improve etc., so I wanted to leave feedback here, to help with the project.

😄

If it looks correct in GNOME then please briefly log into GNOME and run:

  xrandr --verbose > gnome-xrandr.txt

and attach the resulting text file here.

Also if KDE has any monitor colour profile settings then try toggling those.

[Leandro (leandro153-deactivatedaccount)]

ok, thank you 😄

[Daniel van Vugt (vanvugt)]

Please check to see if the GNOME and KDE sessions are actually using Wayland.

[Daniel van Vugt (vanvugt)]

Actually there's a better test for this...

While the problem is visible on screen, please run:

  sudo apt install drm-info
  sudo drm_info > drminfo.txt

and attach the resulting text file here.

In Ubuntu with Gnome, x11, I started without installing it on the pc, just in live.
In Kubuntu it is also with x11, but I was unable to switch to wayland. On the kubuntu login screen, the wayland option does not appear.
I don't know if it influences it, but I believe I installed the system in the minimal installation option.
😅

[Leandro (leandro153-deactivatedaccount)]

tested the latest daily image 24.04, kubuntu 24.04

I believe it's in Wayland, the look is better, more beautiful

only The wallpaper has a little blur,

the distribution is it's beautiful, full of details, very rich

😄

[Daniel van Vugt (vanvugt)]

Try this:

  xrandr --output eDP-1 --set "Broadcast RGB" "Full"

If that doesn't fix it then please attach photos of the screen showing both with and without the bug.

[Leandro (leandro153-deactivatedaccount)]

Thank you, the colors are good
resolved 😄

[Daniel van Vugt (vanvugt)]

That's strange because the files you attached showed that 'Broadcast RGB' had the same value 'Automatic' in both KDE and GNOME. I don't know how 'Automatic' could be giving you a different result in each desktop environment.

[Leandro (leandro153-deactivatedaccount)]

Hi, I also don't know what caused it, maybe it's the resolution of the images, or the colors, details, maybe.

But in Kubuntu 24.04 it is much much better, for me it is much better, in my use I felt that it is better.
Vivid colors, good brightness, good contrast, this is great, good sharpness.

If you can increase it even more, it would be even better hehe
