HD 4600 macOS Sierra, Dual display not working

[bigfede]

Hi to everyone,
I've just set up Sierra; specs:
Z87X-UD5H
i7 4790K (I'm using integrated HD4600)
Clover, last release

the problem I have is:
When I use 1 display everything works just fine, full resolution. The first display is connected via DVI.
I want to connect a second display via HDMI, with cold plug, but it is not working, I see strange images on it, then the second display is not recognized.
What can I do ? I've already tried the guide with no success https://www.tonymacx86.com/threads/...d4600-hd4000-hd3000-framebuffer-edits.125239/)

Hi,

no 1 year after and I not tried to check it or do changes, I worked with this configuration till now.

Now I have installed High Sierra 10.13.1 in other HDD but I can not install multibeast correctly for a problem, but I have the same monitors with clone desktop but without drivers

Best.

I have spent many many hours trying to resolve this this week. I have noticed that at least 4 people report the same problem in this thread (https://www.tonymacx86.com/threads/intel-hd-graphics-framebuffer-edits-desktop.125239/) but for some reason the post author claims them as off topic and they stop posting or their posts are been moved to some other thread, anyway I think Toleda (the above posts author) could help us in this as long we could describe the problem properly. I ll give it a try...
