Display misalignment

while applying tape to try to get the display cable out of the way of the wifi antenna, i discovered that my display isn’t actually taped in place like i understood it to be. i can move it a few mm in each direction with my finger. the left edge of the displayed image is still clipped off, though, even when there’s not bezel in the way. i guess my panel is incorrectly calibrated or something? it doesn’t display at least the leftmost three columns of pixels
