Wall mounted projector wobble
I've got a new school building with SMARTboard SBB885i with UF75W Projector in each room. The projectors are wall mounted and short throw, directly above the boards.
The problem is that the wall construction is lightweight with plywood panels inside to support the board. Minor flexing of the wall caused by doors closing and (to a lesser extent) footsteps causes the projected image to move relative to the board. The steep projection angle magnifies the effect, causing the image to shake up to six inches at the bottom.
Has anyone else come across this problem, and is there a solution?
