Patch Request (Black Screen) L340 17IWL

Recommended Posts

Hi,

I try to get my Graphics to work but the Screen turns Black while Booting.

I use OpenCore from:

 

cause the Hardware of my L340 17IWL is quite similar.

I don't know if the Problem is the config.plist or the ddst patch.

Hope someone knows how to Fix this.

 

thanks in advance.

 

EDIT: My CPU is i5- 8256U Whiskey Lake and my GPU is UHD 620.

Now the Display gets Darker for 0.5s before the screen turns black.

Brightness is Darker after jump then before your patch and its like:

1. The brighness decreases but there is still something on screen like before for 0.5s

2. Screen is empty but still on with same brightness.

The Backlight of the Screen is not jumping on and off.
