HiDpi 1080p on UHD 630 and Dell U2515H

Hello,

I'm writing here because I tried every fix I found online but still coudn't do it.

I have an 8600k (UHD 630), smbios 19.2 on a vanilla Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave install 10.14.6 and the U2515H Dell monitor (2560x1440).

On my macbook pro 15, with switchresx scaled resolution, I'm able to select 1080 hidpi with this monitor. On the Hackintosh I can do 1440x810 or lower hidpi but not 1080 (I can choose 3000x2000 hidpi so it's not an "upper limit" of the gpu). Any help? Thanks
