Black screen Intel HD 530 on Mojave after patching Framebuffer

[ironman2]

Hey, so the difference between your provided plist and mine is about the video ports, so I edited mine and changed it to 3 video ports (you wrote 2). I rebooted : BAM 3 screens worked. I change nothing, I just reboot: Black screen
So I switched the video ports to 4, I booted with 3 screens working, I left it this way, I'll keep it this way for the week, I'm tired of loosing that third screen. But I'm clueless, why does it works once, and not a second time??
I don't know what logs to check to figure out, when it goes black, what to check (not accessible from remote desktop)

Edit:
adding 4 in Video Ports
made this occurrence in the Clover boot log:

168:150 0:000 add device: #PciRoot(0x0)/Pci(0x2,0x0)
168:150 0:000 Add key=framebuffer-patch-enable valuelen=4
168:150 0:000 Add key=framebuffer-con3-type valuelen=4
168:150 0:000 Add key=framebuffer-con3-enable valuelen=4
168:150 0:000 Add key=framebuffer-con2-type valuelen=4
168:150 0:000 Add key=framebuffer-con2-enable valuelen=4
168:150 0:000 Add key=framebuffer-con1-type valuelen=4
168:150 0:000 Add key=framebuffer-con1-enable valuelen=4
168:150 0:000 Add key=framebuffer-con0-type valuelen=4
168:150 0:000 Add key=framebuffer-con0-enable valuelen=4
168:150 0:000 Add key=device-id valuelen=4
168:150 0:000 Add key=AAPL,ig-platform-id valuelen=4
168:150 0:000 Intel HD Graphics 530 [8086:1912] :: PciRoot(0x0)\Pci(0x2,0x0)

Maybe we can patch the framebuffer in the Device properties to provide a cleaner way
but what is valuelen=4? value length ? why 4? is it like 00 00 00 00 ?

At this point, I will suggest you make a new detailed thread with all the info you have till now - this is out of the scope of my knowledge.

3 displays working: 1 HDMI and 2x DP
fully accelerated
Whatevergreen is not used (nothing in its logs), but installed anyway, it renames DSDT

I may have to patch the DP to HDMI on port 0x5, but it works fine without, so I'll see
No Framebuffer to patch, juste used Hackintool to display information

But there is an odd issue with that: I can no longer display Twitter videos with Vivaldi web browser (works with Chrome), while before, with only two display working and 0x1912000 it was working fine...
