Dell Vostro 3681 SFF: restart & display issues with Monterey

[oyko]

Hi,

 

Anyone can give me solution for RESTART / NO DISPLAY problem. 

I succeed install macOS Monterey 12.0.1 even during installation I have to shutdown the PC 3 times by pressing power button (force shutdown).

Because the display won't turn on (blank screen / no display) if the PC restart (LED power and CPU+Fan still running)

I tried to unplug and plug the HDMI cable, but still no display input.

 

 Here the specs:

 

Dell Vostro SFF 3681

-  Chipset : Intel B460

-  Processor : Intel Comet Lake i5-10400

-  iGPU : Intel UHD Graphics 630

-  Wireless : Intel WiFi 3165

NOT WORKING:
