Nvidia 495 10-bit question

Hello

I do have a RTX 2070 Super card and a Philipps 3275 4k monitor, which is able to show 10-bit color depth. In W11 that setting can be easily applied, works across all apps and looks pretty nice.

To achieve something similar in EOS, I edited the DefaultDepth to 30 in xorg.conf, although in nvidia-settings the max color depth is only 8-bit. However, the driver showed me Color Depth 30 in the nvidia-settings and the desktop looked even better (KDE).

But my Latte panels got a big black solid stripe in the background and Brave also got framed with a thick black stripe. It seems, that not all apps get along with the 10-bit setting and I’m not sure, why I can manually change it, but nvidia-settings doesn’t offer it.

Is this something, that’s just is as it is (the stripe thing) or is there something one has to additionally install, when using 10-bit color depth?

Thank you

AMD supposedly supports it but i think also there are a lot of varaibles. Depends on the graphics card, monitor, and display server to name a few.

I don’t see any info on Nvidia? :man_shrugging:

Edit: Honestly from what i see it’s not worth even looking at …right now!

If you want some info on HDR in Linux this seems like a good page:

Supposedly Plasma 5.24 is supposed to be working on 10 bit color support as well shrug

Interesting read, thank you.

The solution seems to be, there is none atm. At least not an easy one, since GTK seems to be the problem.
