Question Projector recommendation - 21ft wide x 9ft tall

Hi,

I bought a Carl's place screen.

I need a projector to light up 21ft wide x 9ft tall (2.4 aspect ratio). I have a Panamorph UH480 lens that I can use.

I'm having trouble finding a projector that:
  • Suports vertical stretch (do I need to use an A-lens?)
  • Lets me have at least a 25ft throw (some of the things I see are fixed throw)
  • High enough lumens to produce a watchable image (4500-5500+ lumens?)

Budget is under $5000, I'm open to stacking or blending if you can give information on that - but I'm guessing neither of those techniques are needed.

Thanks!

If you're looking for both brightness AND contrast, a pair of Epson 3700 projectors can keep you around 14ftL-16ftL with impressive native-contrast while their optical lens-shift can help you align the pair more easily than models without lensshift.
They also feature a large amount of zoom-range which barely affects their brightness.

Being hometheater projectors rather than business models, there's a better chance they support vertical stretch, but I'm still not sure whether they do or do not.

The natural 10%-20% light lost from additional optics (particularly lenses which don't cost a fortune) often leaves many A-lenses with little or no real brightness advantage, so I wouldn't personally worry too much about NEEDING a projector that supports vertical stretch.
A pair of 3700's can keep around 14ftL-16ftL on a 21ft-wide white Carl's screen without using an A-lens.
They'll need to be setup at least 28ft-29ft back from the screen to fill it...If you want to place them farther back, you can go as far as 40ft-45ft back if needed, or anywhere between ~29ft-44ft.

Easy $25 DIY black (or any color) ALR paint +$40-$50sprayer screen mix smooth/clean and very easy to learn spraying with little/no mess.
Simple $25-40 DIY black/dark-grey ambient-light rejecting screen, grab two things from a local store..mix..roll..done.

I ended up buying an Epson G7500U (refurbished). Let's see how it does, should be about 20ftL without A lens. Also does 4k enhancement so maybe the pixels lost from zooming won't be as visible from seating area which is 30ft away.g
