I just finished designing cases for the FYSETC PanelDue clones (7 inch: https://www.thingiverse.com/thing:4076242 and 5 inch: https://www.thingiverse.com/thing:4069067). I noticed that on my 7 inch screen, the LCD panel doesn't line up with the black outline on the PCB board. Is this normal? Are all of the units from the factory lined up the same or are they all different?
