[SOLVED] nvidia-settings CLI cannot --assign with display device arg

Hello,

I have written a script to change DigitalVibrance via

nvidia-settings -a DigitalVibrance=716

depending on what window is focused.
It works fine, but I want it to only change for one of my three monitors. When I try to pass a display device in accordance with the nvidia-settings man page, I get an error.

nvidia-settings -a DigitalVibrance[DFP-4]=0
zsh: no matches found: DigitalVibrance[DFP-4]=0

I have tried so many different aliases inside the square brackets, using the output of nvidia-settings -q dpys, but to no avail. I have tried specifying a screen or gpu in the initial section of the command "-a [gpu:0]/Digi..." but still nothing.
Output of nvidia-settings -q dpys:

        DPY-6
        DP-4
        Connector-1

    [7] toby-arch:0[dpy:7] (DP-5)

      Has the following names:
        DFP
        DFP-7
        DPY-7
        DP-5
        Connector-1

In the GUI of nvidia-settings, I can change DigitalVibrance along with other values on a per monitor basis, I just wish I could get the same functionality from the command line.

This is my first time posting so apologies if there is any gaping hole of information I am not providing.
Thanks heaps.

Re: [SOLVED] nvidia-settings CLI cannot --assign with display device arg

nvidia-settings -a "DigitalVibrance[DFP-4]=0"

Otherwise zsh interprets the brackets…

Re: [SOLVED] nvidia-settings CLI cannot --assign with display device arg

The error message you get is because zsh specially and specifically interprets the brackets. nvidia-settings is never run with that error message.

you need to escape the square brackets so they are passed as is to the command. try

nvidia-settings -a 'DigitalVibrance[DFP-4]=0'

Edit: FFF...uck But holy hell I'm late

Re: [SOLVED] nvidia-settings CLI cannot --assign with display device arg

Thanks so much guys, can't believe that was the problem. It still was changing all three monitor at first but I put the gpu target at the start and now I can control each monitor individually.
