Integrated Graphics stuck at 30Hz

Hi,

I am new to Arch Linux (about 1.5 months of experience), and I've been running it generally fine after following the wiki, though I still very much consider my build to be a work in progress. That said, I've come across my first issue after a recent upgrade to my computer. I am now using an 11th gen i5 11600k as my processor, and I am trying to get the iGPU to output 4k60. The specifications (https://ark.intel.com/content/www/us/en … 0-ghz.html) for the processor definitely list 4k60 as within its maximum range using a DP connection. I've tried following the wiki here: https://wiki.archlinux.org/title/Xrandr … esolutions, but when I run xrandr I get the following error message.

$ xrandr --output DP1 --mode 36840x2160_60.00
xrandr: Configure crtc 0 failed

Connecting to my display through the dGPU does yield the 60Hz option, but the intent of my new system is to eventually completely virtualize Windows using VFIO, so I need the graphics card for pass-through. I may eventually just get a second, low-end GPU to do the job, but with the market right now that wasn't an option. I do multiboot, and I checked on my Windows partition to see if installing the proprietary drivers would drive the iGPU to 4k60, which it does. So that leads me to believe that I have somehow misconfigured my drivers in my Arch installation.
Obviously, I wasn't able to figure out what the aforementioned error message meant, so I'm hoping someone here could help me out. Thanks.

Potential points of interest:
I do have a dGPU installed, but it is not connected to a display, so I do have xf86-video-nouveau installed on my system alongside xf86-video-intel.
I am using KDE Plasma.

xorg log?

Also "36840x2160_60.800" is not 4k, there's a "6" too much…
