Hi,

Not sure if this really a post install issue, but I give it a try. :)

As still fresh on the "Hackingtosh front" I started of with Clover, Uni/Multi Beast, etc. about 8 weeks ago, a lot of hassle to get stuff work and never able to upgrade to the latest Catalina. Last Friday removed everything related to Clover and created an OpenCore install USB with Catalina 15.7. now three days later, I have it more or less running (instead of three weeks following multiple Clover based tutorials).

But... Now it comes.... I have an issue with graphics (followed the Dortania guide). when I boot with second monitor on HDMI from my HP AIO it hangs on IOConsoleUsers: gIOScreenLockState 3, hs0 , bs0, now, sm 0x0. When I unplug the HDMI it gives me a login screen and when I plugin HDMI after that, it works as expected. (extended desktop, not mirrored). changed AAPL,ig-platform-id 0300220D to AAPL,ig-platform-id 0D220003, that makes me able to boot with my external monitor, but gives me; Intel HD Graphics 4600 7 MB and a mirror screen.

I'm running a i5-4460T (with Intel® HD Graphics 4600) on a HP Pavilion AIO pc.

My DeviceProperties:
DeviceProperties->Add->PciRoot(0x0)/Pci(0x2,0x0)


AAPL,ig-platform-id Data 0D220003
device-id Data 12040000
framebuffer-fbmem Data 00009000
framebuffer-patch-enable Data 01000000
framebuffer-stolenmem Data 00003001


If more information is needed....?
Also if this is already addressed and there is a link/thread?

Any help will be really appreciated.
Thnx in advance.
