Can't run higher refresh rates on nvidia-dkms 510+

Hello, for a while now I've been running into this issue where I cannot seem to run refresh rates higher than 60hz on 4k on my "monitor" which is an LG C1 TV. I used to run on 4k 120hz without issues. Everytime there has been a new nvidia update I've checked it out if has been fixed but nothing so far. I'm using 'downgrade' to get back to the last version that works which is 495.46. I have searched for solutions but nothing that has been posted recently looks like my particular case. I first thought it had to do with issues with DSC but then read this was never really a thing on linux anyway... Anyone ideas?

EDIT: Useful info: I'm using a DP 1.4 (dsc) to HDMI 2.1 active adapter from Club3d and my GPU is a Nvidia RTX 2070 Super.

Please post the output of "xrandr -q" and your xorg log, https://wiki.archlinux.org/title/Xorg#General
You could try https://wiki.archlinux.org/title/Xrandr … esolutions for

Re: Can't run higher refresh rates on nvidia-dkms 510+

Hey sorry for the late reply, I've been really busy lately and for the time being I just kept using the older Nvidia driver. Thought it's really time to move to the newer driver so I have to fix this. I've tried simply adding a new modeline like you suggested but that gives me:

❯ xrandr --addmode DP-0 "3840x2160_120.00_rb2"                                                            
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  43
  Current serial number in output stream:  44

I feel like this is some kind of limit being enforced to keep the user from adding new modelines that are potentially unsupported by the monitor- but I could be wrong.

Interestingly however is that the EDID clearly says that 4k 120hz is supported.

Re: Can't run higher refresh rates on nvidia-dkms 510+

You found the ModeValidation option in /usr/share/doc/nvidia/README … though still

The 120Hz mode is interestingly in the YCbCr 4:2:0 section only - so here's some brainless copypoasta to read on…

Using 4K resolutions over HDMI requires a high single-link pixel clock that is
only available on Kepler or later GPUs.

Using HDMI 2.0 4K@60Hz modes in the RGB 4:4:4 color space requires a high
single-link pixel clock that is only available on GM20x or later GPUs. In
addition, using a mode requiring the YCbCr 4:2:0 color space over a
DisplayPort connection requires a GP10x or later GPU. If driving the current
mode in the RGB 4:4:4 color space would require a pixel clock that exceeds the
display's or GPU's capabilities, and the display and GPU are capable of
driving that mode in the YCbCr 4:2:0 color space, then the color space will be
overridden to YCbCr 4:2:0. YCbCr 4:2:0 mode is not supported on depth 8 X
screens, and is not currently supported with stereo or the GLX_NV_swap_group
OpenGL extension.
"NoEdidHDMI2Check": HDMI 2.0 adds support for 4K@60Hz modes with
         either full RGB 4:4:4 pixel encoding or YUV (also known as YCbCr)
         4:2:0 pixel encoding. Using these modes with RGB 4:4:4 pixel encoding
         requires GPU support as well as display support indicated in the
         display device's EDID. This token allows the use of these modes at
         RGB 4:4:4 as long as the GPU supports them, even if the display
         device's EDID does not indicate support. Otherwise, these modes will
         be displayed in the YUV 4:2:0 color space.
Option "ColorSpace" "string"

    This option sets the preferred color space for all or a subset of the
    connected flat panels.

    The option string is a semicolon-separated list of device specific
    options. Each option can optionally be prepended with a display device
    name and a GPU specifier.
    
        "<dpy-0>: <tok>; <dpy-1>: <tok>; ..."
    
    
    Possible arguments:
    
       o "RGB": sets color space to RGB. RGB color space supports two valid
         color ranges; full and limited. By default, full color range is set
         when the color space is RGB.
    
       o "YCbCr444": sets color space to YCbCr 4:4:4. YCbCr supports only
         limited color range. It is not possible to set this color space if
         the GPU or display is not capable of limited range.
    
    
    If the ColorSpace option is not specified, or is incorrectly specified,
    then the color space is set to RGB by default. If driving the current mode
    in the RGB 4:4:4 color space would require a pixel clock that exceeds the
    display's or GPU's capabilities, and the display and GPU are capable of
    driving that mode in the YCbCr 4:2:0 color space, then the color space
    will be overridden to YCbCr 4:2:0. Full color range is still supported in
    YCbCr 4:2:0 mode. The current actual color space in use on the display can
    be queried with the following nvidia-settings command line:
    
        nvidia-settings --query=CurrentColorSpace
