Dual Monitors Don't Work Since Updating to 10.13.5

Hi guys,

I have a lot of time in this community and I have learned a lot about hackintosh thanks to its help, today I come here because I have a big question, I had OSX 10.13.2 and the dual monitors of my hackintosh thinkcenter worked, but since I updated to 10.13.5 I can not make it work, I do not know if someone can help me, I'm going to leave the EFI that I currently use. Thanks in advance.

- Desktop Lenovo ThinkCentre M710s SFF 10M7
- Procesador Intel Core i5 7400 a 3.0Ghz 7th gen
- 8GB DDR4
- Disco Duro 1TB
- Kaby Lake Intel HD 630

...if someone can help me...

Dual monitor constantly gives me pain. Not only under macOS but also, the thingy is dual boot, under Windows 10. Today my resolution was to 1) unplug the 2nd monitor, 2) boot into macOS and 3) plug the 2nd monitor.

I, too, had problems with multiple monitors and lack of operating DisplayPort on my graphics card after updating to 10.13.4/5. I solved the problem my using a System Definition of iMac14,2. (I was using 18,3 for my Coffee Lake based system (MyHero II).) So, I recommend using the iMac14,2 SysDef.

Thank's for your recommendation, but my Hack has been an iMac14,2 for a long time. This SysDef is apparently not a solution for every dual / mutiple monitor-problem.

Ah, nice that it worked for you too!

I have returned, to comment that sometimes the two monitors work and sometimes, when I plug in the second monitor, the hackintosh restarts, and I have struggled to make this work.
