Hello all,
I dont normally post, just mainly read/research. I have come across a problem of my own that seems odd to troubleshoot.
Backstory: currently I am in the process of making a portable desktop using a pelican case (not new, I know), but I travel a lot and my old gaming laptop is about done for. This will be a carry on during flights.
So everything is about put together when I decide to test the screen to make sure it works. I purchased a new replacement laptop screen (N173HGE-L21) and a LVDS controller board. When I first booted up my PC, the left half was displayed backwards and the right half was normal. There was also 2 black fat strips down the middle. This persisted in BIOS (both IGPU and GPU). BUT when I plugged my laptop in, it displayed just fine. What would cause this? Sounds like a bad inverter/screen, but it worked fine when my laptop was in. It isnt my GPU since it does this with both IGPU and GPU. Then everything is fine when I plug into my main monitor.
Let me know if you need any other information, and thanks.

prolly just incompatibility between the board the your controller..
idk, maybe check for new firmware.. or maybe there's jumper for something.

Well the controller board did come from china, but from what I have seen is the board is about the same with different screens. The type of screen will dictate what kind of plug you get from controller board to screen. I just found this odd. I ordered another one from here in the states. The wires in the picture already looks thicker and better color coded.
