Having mounted a second-hand 92" Optoma DS-9092PWC from the ceiling, after a few days, I noticed that both sides of the picture were equally ascew. Apparently, the lower part left and right were bulging inwards. Let it hang a few days to see if it would straighten out, but it only got worse, until noticing that the canvas actually was loose on one side. Does anyone know how a screen is attached to the lower bar and how to fix it?
