There's a 1/4" White Line across the bottom of Newly-Replaced Screen

I recently replaced a cracked screen in my steam deck OLED (512 GB) and a white bar appears across the new screen when I boot it up. Everything else looks alright, if not a bit low-resolution. The white strip blocks out UI and gameplay that expect that part of the screen to be working. It does scale in brightness along with the rest of the display, and occasionally red and yellow horizontal strips appear inside that white strip

I have uninstalled, then reinstalled this screen three times trying to see if it was the connector and making sure the pins matched the instructional photo. This is the result each time. I would put my old screen back in to test, but it has been shattered and will not display anything. I am wondering if this may be a compatibility issue or if perhaps I received a defective screen replacement. Here some images of the display model#s in case that helps.
