Black screen issue

[uzairblaoch]

I’ve dell inspiron 5577
i7-7700hq intel hd 630

Graphics are not working
I somehow manage to install big sur but graphics doesn’t work. If i use your platform id under device properties black screen issue; just went black after booting the same thing appeared on catalina before. If connect laptop with hdmi screen works as external but on laptop it’s black.
I also tried my catalina devices properties but it doesn’t boot at all. Stuck there.

I upgrade my catalina (clover) into big sur (opencore)
I somehow managed to install it but no graphics acceleration.
I’ve dell inspiron 5577 laptop
Core i7 7700hq
Intel hd 630

I’ve tried everything things. If i use platform id : 000001B59
Device id : 1B5900000
Laptop screen goes black it seems like big sur booted but no display.
The exact same problem I encountered on catalina (clover)
I tried different combinations and got succeed with
Platform id : 0000001B19
Device id : 1619000000

If i use same for big sur (opencore) it doesn’t boot at all

It says something like “reported as SMC 1
Can’t find dpmicro “

How did you get big sur running? Can you please provide me your EFI folder.... I want to install big sur.... Thanks.

I'm sorry, I don't know much about OpenCORE. I don't have much time to learn now. Maybe some computers don't support it. But I can't determine the source of the problem and how to deal with it
