Surface Book 2 - internal monitor black


1 post in this topic

Recommended Posts




Surface Book 2 - 13 inch.

CPU: i7-8650U

GPU: Intel UHD 620

Display res: 3000x2000


The iGpu only works on an external monitor plugged in to the usb-c port.

The internal monitor has the backlight on, but is otherwise black.


The bios does not have an option to change DVMT.

I've tried doing an EDID patch into config.plust by grabbing the EDID in Windows.

Unfortunately it did not help.

I've attached a series of debug files.

Does anyone have suggestions on what I can try to get the internal monitor to work?
