My original monitor is n156hca-eab, and the replaced monitor is n156hce-gn1, both of which are 1080p.

Hi,

Does everything work normally in Windows or Linux? To be honest, I don't know why macOS wouldn't boot with your new display. You could try to reset NVRAM and see if it helps.
For NumLock light, you can use YogaSMC to configure the behavior.
I just merged a PR, can you try if that fixes the OC error? I don't have access to the laptop anymore so I am not able to test myself.

Let me try this new project.
Everything is normal in windows. I tried to reset NVRAM and couldn't solve the problem. I looked up the online tutorial and tried to inject display EDID code, but I couldn't complete the injection without other macOS computers.

This is my display EDID code：
00FFFFFFFFFFFF000DAE0C15000000002A1C0104B522137802EE95A3544C99260F505400000001010101010101010101010101010101363680A0703820405036680058C110000018363680A0703820405036680058C110000018000000FE00434D4E0A202020202020202020000000FE004E3135364843452D474E310A2001D1

I tried the latest project. doesn't boot macOS

I don't really see any errors there. So does the screen go black or is it completely stuck here and nothing happens?

[yusifsalam]

Also, have you tried connecting your laptop to an external monitor?

Is it completely stuck here and nothing happens.
I tried connecting to an external monitor,boot macOS normally.

Very interesting.
To be honest I don't really know what could be causing the new display to not work with macOS but this does not seem like an issue with my config files since both the old display and external monitor work. I'm not able to help any further so I will convert this issue to a discussion, maybe you can get some help from someone else there.
