Image and display backlight are present while macOS is load but the display turns off before log in. The laptop is working (hear sounds), but without image and backlight. Internal LCD normal is worked in safe mode also when connect external LCD.
I think the problem is with the integrated graphics iGPU.
Is it possible to disable iGPU ?
