Need documentaion on how to get nixos on raspberry-pi-4 working correctly with dual-monitor setups(2k, 4k, etc).

I finally gave up on trying to get my two 2k monitors to work correctly with nixos on raspberry-pi-4, if you any of figure this out, then let me know. For now, I'm just sticking to one 2k monitor. Thanks in advance for the help. Models: LG regular 32inch, 2k. LG ultra-wide screen 34inch, 2k. modele features: freesync, hdr, etc.

Using the settings from this config.txt(the dual hdmi monitor fix is located at the bottom of the file) https://gist.github.com/donrestarone/5edfee56f2da086bc173c25b3d6fb225 , I was able to get the pi-4 to render to both 2k monitors, but the rendering was all messed up, a quarter of both screens became black, everything slowed down, and there was a lot of lag. Maybe you could tweak settings from this config.txt file and get it working correctly. Thanks in advance for the help!
