The acrylic box that I ordered together with the display was cut incorrectly.
If I try to fit it so that the holes line up with the connectors, it doesn't fit well on one side.
If I turn the frame so that the display goes in, regardless of the position of the connectors, then the bottom cover is displaced and cannot be engaged with the screws.
The box is unusable.
The display for now works as I expect.
