I am running 435.17-3 with a Gefore 1050Ti + HDMI + Eizo CS2730 but I still see banding with some test images. I have added 30 bit option to xorg.conf and xwininfo shows 30 bit:
xwininfo: Window id: 0x1ed (the root window) (has no name)
Absolute upper-left X: 0
Absolute upper-left Y: 0
Relative upper-left X: 0
Relative upper-left Y: 0
Width: 2560
Height: 1440
Depth: 30
Visual: 0x21
Visual Class: TrueColor
Border width: 0

Colormap: 0x20 (installed)
Bit Gravity State: ForgetGravity
Window Gravity State: NorthWestGravity

Corners: +0+0 -0+0 -0-0 +0-0
-geometry 2560x1440+0+0
In general it does support this. Sometimes this is a bit fiddly since for some reasons, it will use dithering. The main pitfall is that most DEs like Gnome/Mate don’t support this so you will get wrong colors and mouse clicks won’t have effect.
Please set
You have two xorg configs:
/etc/X11/xorg.conf
/etc/X11/xorg.conf.d/my-xorg.conf
that’s not advisable, please remove one. Furthermore, you have ForceCompositionPipeline=On set, don’t know if that’s compatible with depth 30, please remove it.
The screenshot is an 8bit png, so that doesn’t really help with seeing any difference.
According to the Xorg log, 30bit depth should be active, also no dithering is enabled. So it’s a bit odd. Maybe some problem with gimp, do these pictures help?

The whole point of this screenshot was to show you that in reality the 30 bit image shows the exact same banding as the 24 bit image. The screenshot is just a visual evidence to underline my point.
This is the same. regardless if I do 24 bit or 30 bit I see the same banding.
I am really lost. The nvidia-settings app shows “Depth 30”. xwininfo shows “Depth 30”. The monitor is for sure capable of 30 bit. And the cable is DisplayPort provided by Eizo. I have a ticket pending with Gigabyte to see if the graphics card is limited (GIGABYTE GeForce GTX 1050 Ti OC 4G). I am running out of ideas what else to check.
Is anybody else here in the forum successfully running a GeForce GTX 1050 Ti with 30 bit?
I have the EIZO color profiles activate which came with the monitor. One for 5000 K and one for 6500 K. Makes no difference. And the same is true with gnome by the way.
Thank you for that link. But besides of the availability of Windows installation files,
I do not have a partition where I can install it. I am afraid I can not test that.
