NVIDIA developers, I would like to ask questions regarding bit color and whether or not this driver release will resolve it in Linux ? My questions are : "
- Is my monitor(AW3423DW) outputting 8 bit or 10 bit color in Plasma Wayland 6.2.2 ?
- If the bit color output is wrong, will this driver(565.57.01) fix the bit color in my monitor when I enable the HDR option in Plasma ?"
I was checking my system information on Steam and in Desktop Color Depth, it said 24 bit color.
I was curious whether or not that was true or not so I scrolled around the internet for more information about bit color and I have learned two commands that query the bit color that is showing and I am conflicted on whether or not my monitor is displaying 8 or 10 bit color ( on Plasma Wayland).
One command I have used first to query the bit color is xdpyinfo , under āsignificant bits in color specificationā it says 8 bit . But when I use drm_info , under āFormatā it says ABGR2101010(which from a Reddit comment confirms that this is 10 bit color). Could you confirm to me whether Plasma( or specifically Kwin, correct me if Iām wrong) is outputting the correct bit color( with hdr disabled ) . And if you confirm that the output of the Kwin compositor outputs the wrong bit color, will this driver release fix that or on a future release ?
Thank you for reading
