display port dp1.2 on catalina

[emigre]

Hi there! I have a mac pro 4.1 with gtx660 3gb running catalina by dosdude’s magic. I would love to get 4k @60hz to my dell monitor but somehow there is no signal coming through displayport 1.2..only hdmi & dvi. anyone who’s able to use displayport? is it even supported in macpros?

No worries. I have fixed my Display Port problem in Catalina by changing my iMac 2011 to iMac 2012 using OpenCore.

However do bear in mind that there seemed to be a sleep problem for my set up - https://www.tonymacx86.com/threads/catalina-imac-2011-pretend-to-be-2012-panic-during-sleep.300341/
