Perhaps these pictures will help you see what I mean from the description above.
This first picture is of the box with the frame facing downwards. You can see the “lip” created by the frame going all the way around the edge of the box. The opening of the “lip” should be the same as the bezel of the monitor. This way you don’t see the bezel when you put the monitor in. The monitor is held in place by the “lip” and conceals the bezel at the same time.

The second picture is of the frame facing up with the box below. When you put your mirror in (first, from the box side) and your monitor on top of that (second, from the box side) they will both rest on the “lip” created by the frame.

It will then look like this from the box side. I simply used two “L” brackets to keep the monitor and mirror from falling back out of the box when you pick it up. You can just see them. One at the top of the picture in the middle and one at the bottom of the picture in the middle.

Mine looks like this when you hang it up. The little teddy bear hides the power cord at the bottom.
