I'm looking for an HD projector to use for backyard movies. I want to use a large screen (perhaps 9' x 16'), and I want a projector that will be bright enough to run during summer evenings when there may be some lingering light.

I considered using the Optoma HD65 only because I can borrow this model from my father-in-law. Well, this projector actually can create an image at my size requirements at 12 or 13 foot lamberts. The catch: it's only 720p native.

Why can I not find a reasonably priced 1080p projector that will perform similarly? What is it about the higher resolution that makes it harder to come by the higher brightness?

I assume you checked the "Search by Feature" here? What is your budget? Approximate throw distance?

The cheapest 1080p that will be bright enough is the Optoma EH1020, but it is a multi-purpose projector. It got a prettty good review here. At 220" diagonal and a 24' throw distance, it will give you 21 foot lamberts, according to the info here. Also, it doesn't list the color wheel speed. It being a "multi-purpose" projector, it might have a 2X color wheel speed, which might mean rainbows for you and/or your guests.

Thanks for the reply. I was trying to limit my search to the "home theater" projectors. The one you mentioned only produces 10fL when set to video mode. I can achieve 13fL if I cut my image size down to 196" diagonal, which may be a better size for me anyway. I think I will go back to the database and search among the multi-use projectors. Is there any reason I should not consider using a "conference room" projector for movies?

There are many reasons not to use a conference room projector, but most of those reasons apply to critical viewing home theater areas. You arne't viewing in a conference room NOR in a home theater, so I would go for the brighter which can help deal with poor situations rather than the better image quality which mostly comes through in a perfect theater setup on a normal sized screen.

The biggest disadvantage is most likely the 2x color wheel. But, beyond that, you have some pretty good solutions.
