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
