Turning dithering off for Nvidia cards in Linux

Seagull

Hi all,

This is mostly aimed at @JTL and @Slacor as IIRC they are linux + nvidia people

Is it right that in Linux I can turn off dithering for Nvidia cards? How does one do this? and do I need to be using a certain distro?

I want to do some PC gaming again, and if I can easily turn off dithering in Linux, it might be the easiest route. The trick I learnt of simply trying all the colour settings till I find one that doesn't dither in windows is no good to me, because the monitors I use at the moment have only DVI connectors, and I seem to only get one colour option unless I use either DP or HDMI.

Of course this all has to wait till I can actually buy a video card!

This is what I see with NVIDIA X Server Settings with Linux Mint 20.1 Cinnamon, which is what I use primarily.

I can change it to Auto, Enabled, Disabled

@Slacor do you use this with Dithering Disabled normally?

Slacor

ryans I have been running it disabled. I'm not certain whether it has made a difference in my case.

If monitor is a true 6bit or 8bit without FRC, you don't worry about dithering.

Aquila No, because it is entirely diffrent type of dithering, produced by videocard itself, not monitor.

You can check dithering with a magnifier

I want to add that merely changing the setting is not enough. The setting will apply immediately, but it will not survive a reboot. To make it work permanently, you need to run nvidia-settings every time. It has an option that makes it run without loading its GUI:

nvidia-settings --load-config-only

Put this line in your deskop environment's autostart list and you're good to go.
