I damaged my screen. Ordered the B-stock (A-stock wasn’t available) and the new screen doesn’t seem as good as the original. I can see the pixel lines, especially on night shift mode, and the image overall is not as crisp as it was. Can the wrong screen cause this? I try reinstalling the screen connector and that didn’t help.
Can you post a good set of images so we can see. You might want to try an external monitor to verify things as you might have something else going on here. If you do think you got a bad display then you should contact the IFIXIT store directly for a replacement. Here’s their contact info: Contacting IFIXIT
