YoYelloW Posted January 9, 2018 Share Posted January 9, 2018 Hi. I'm using a HP Z240, running 10.13.2. It works, but I only get video on 1 screen. Im using 2 fullHD screen over DisplayPort. 1 works and the other one does not work, only during clover it shows a mirrored screen, during boot it goes to sleep. The Motherboard is somewhat special of the Z240 SFF, it only has 3 Displayports as video out. Im not using a gfx card, just the intel graphics of the i7 6700, thus a 530. I found this post describing some information regarding the video out ports, but so far I haven't figured out how to change this. Right now im using a clover folder from Maldon, he could not help me with the 2nd DP. I figured I have to change the ports using KextsToPatch in clover but im not sure exactly how. if someone can help me or give me pointer it will be much appreciated.

YoYelloW Posted January 10, 2018 Author Share Posted January 10, 2018 I have been trying to get this to work by adding some ports in the KextsToPatch in the clover config. so far no result. From what i have found now the default ports are all DP in the config, and these can be changed by pathing them. This would mean thati do not need changes as i actually do have 3 DP ports. I have tried with and without intel inject, added the ig-platform-id. i tried removing IntelGraphicsFix.kext, no changes.. Still only 1 screen survives mac os boot... and i cant figure out why the other ones goes black... anyone got ideas?

YoYelloW Posted January 10, 2018 Author Share Posted January 10, 2018 I just figured out that booting with just 1 screen works on all 3 ports, so they do work individually, but now when they are both connected...

demos41 Posted January 11, 2018 Share Posted January 11, 2018 Hallo, I have 2 dp and both monitors work, on all as yours. The trick is to switch on the monitor when it is near the login screen, the second monitor turns on after a blank. natively they both turn blank if both switched on from boot.

YoYelloW Posted January 11, 2018 Author Share Posted January 11, 2018 Yes i now have it working. The trick was to run the AGDPfix app and boot the system with 1 screen of, when the system is booted i can connect the second screen and everything works.
