So i followed basically the answer in this answer, but neither SwitchResX nor RDM activate 1920x1080 "HiDPI" resolution. I am using 2 LG UltraGear 27GP850 1440p displays. I saw someone else had the same issue, but there were no answers.

The only thing from the guide i didn't do was deactivating SIP, since this seems to be no longer needed in Monterey.

Did anybody face the same issue and maybe found a solution?

I have fixed this problem. Everything done like in the linked guide, but I needed to select a 1920x1080 resolution with either 144hz or 120hz, the others won't work. But this only worked with SwitchResX for me.

Problem solved, hopefully this can help someone!
