  1. MacBook Pro
Installed Catalina 10.15.4 (19E287) Vanilla with OpenCore on my HP Elitedesk 800 G2 Mini.

Everything is working (Wifi isn't but I'm using Ethernet anyway) but my second display.

I'm trying to get them both connected via DisplayPort as the only other output on my computer is VGA.

I've tried manually setting the framebuffer arguments, but I cannot get it to output to both displays. Yet if I unplug one and restart, it will use the other one just fine.

Any help would be greatly appreciated.

Update.
Disabled SIP and ran AGDPfix now both monitors appear on System information and Hackintool as connected but still no output on the second monitor.

After re-enabling SIP both displays now work perfectly.
 
Hi.
I'm having a similar problem after an upgrade to Catalina OS X 1.15.4 (even with additional patch 19E287) and I saw your thread.
I know how to disable SIP on diskup start, but... could you specify more what to do to run "AGDPFix" (where you download it, etc)?

UPDATE: I ran this AGDPFix I found here https://www.insanelymac.com/forum/files/file/424-agdpfix/ but no success. Before enabling again SIP, System information is not showing my second display, just the built-in retina monitor :(

Sometimes plugging the second monitor in after login is needed. Not all the time, and I don't really know what prompts it so i've just took to unplug the monitor before turning the system on and then plugging in once logged in.

Not perfect but the computer is that small it's not really an issue for me.

Just tried. Second monitor worked up until the iGPU driver text in verbose came up, then second screen went off. Also if I unplug the cable for the second monitor once at the login screen it crashed the system.
