Set initial graphics to CPU and iGPU multiple screen enabled fix the problem. But I don't see os loading progress till login window
It's because BIOS and macOS initialization uses priority GPU for output. And only after base system is loaded secondary GPU starts to send output signal.
I haven't found any solution for this problem. Merely plugged main monitor into iGPU (I don't need GPU power under macOS - all my games installed on windows).
BTW - with HD4600 macOS interfaces work smoothly and fine)
