vega 56 nano blackscreen

[fLatra]

Hello, I'm facing strange issue after updating from 10.14.1 to 10.14.2

My setup is:
- i7-8700k
- asus rog strix z370-i
- vega 56 nano
- main DP monitor with 144hz
- secondary HDMI monitor

Previously all have worked perfectly and now after main monitor goes to sleep I cant wake it up. its stuck with a blackscreen.
Basically when I'm locking my computer all monitors go to power saving mode and then only secondary wakes up normally.

So I've tried some fixes like
- whatevergreen.kext
- VegaGraphicsFixup.kext
- adding RadeonDeInit = true
- adding ig-platform-id = 0x59120003
- run multibeast again
- changing ProductName from iMacPro1,1 to iMac18,2-3 or iMac14,2

And nothing helps
And then I downgrade my refresh rate on main to 59,88hz (NTSC) and now the sleep\wake monitor feature working but I'd like to return 144hz
Has anyone facing this issue and how can I fix it?

@fLatra, please update your profile (personal details) with your Motherboard, CPU and iGPU or Graphics Card(s).
If you have a prebuilt computer enter make and model instead of motherboard.

I have to many builds so I mentioned the setup inside the #1 post. No problem, I've added the current as #nfc.
