So, I am pondering over whether I should upgrade my 7 year old projector or not...and if I do, will I be able to use it to project in my backyard, on a 16' by 9' screen (don't have one, but that is what I would get). Does anyone have any experience with using a Sanyo PLV Z2000 outdoors? How bright is it if there isn't a lot of ambient light, just a normal amount in a neighborhood that is somewhat spaced out...
