I recently got the N3 Ultimate and noticed a faint light border extending beyond the projected image area.

It's visible even when the projector is perfectly centered on the wall with keystone correction and lens shift completely disabled. When I use lens shift, the light border becomes noticeably wider.

Is this expected behavior with DLP projectors, or is there something specific about the N3 Ultimate causing it? Curious whether other N3 owners are seeing the same thing.
