Wrong panel
I bought a NV156FHM-N4J but I received NV156FHM-N4K. It arrived with a rusted connector. I cleaned it and now it works. I don’t wanna get into sending it back as I have opened the screen protector to check the panels colors. Visually its very flat and dark. Yes, it is full brightness. Even after some tuning in amd adrenalin still not as I would like.
