Original Question:
Hello, tonight i've updated my hackintosh was on El Capitan. I used SwitchResX to use 1440p res and it worked perfectly, but now on Catalina, in 1440p my screen is blurry and I don't understand why, but 1080p works perfectly. I think it's probably about my SMBIOS who's simulate a non-retina display but I can't change it because my computer restart if i use iMac 16,2 instead of 14,2.
Any ideas? Thank you :)
