just bought the hc from regalcamera.com for 1300 and an elite screen for 250 looks to be pretty good just starting to set it up

JayDo - I'm not sure exactly what you are trying to accomplish. In any non-specific projection setup that does not meet that fairly tight standards of the 'average' home theater, you are going to find yourself spending a lot more than 'average'. An average entry level projector/screen typically runs from about $2,000 to $5,000. With your budget on the low end, you must make your environment match standards.

This means about a 10-14 foot throw and about a 100" diagonal in a completely dark/near completely dark environmentally controlled environment. Anything OTHER than this will require an increase of funds - usually measured in the thousands of dollars for EVERY change that you wish to make from the norm.

1. Is the projector in an environmentally controlled environment?
If not and you want something 'durable' forget it, it doesn't exist as far as I know.

2. Is the screen in an environmentally controlled environment?
If not, then you can go with a white painted wall or something that is 'cheap' to maintain because it will need to be replaced regularly due to environmental conditions. It is possible, a good piece of white vinyl will last a bit longer but it will need to be carefully cared for.

3. Is your throw range 10-14'?
If not, then you will need long throw lenses or a change of your setup to allow for rear projection. If you need 30+ feet you will have to find a compatible projector and a long throw lens which may run $2,000 to $10,000 for the right lens.

4. Is the environment completely light controlled/near dark?
If not then the real world lumen output needs to be increased. Instead of theater standard 12-17 lumen per squre foot you should expect about 50 lumen per square foot for 'board room' light levels. Sunlight light levels tend to be unreaistic unless you go with a black screen ($$$) and a high lumen projector ($$$)

It really sounds like your setup meets absolutely none of the standards of the industry - which to me sounds like a $25,000 installation to do properly. Likely more.

Wow. Somehow I guess I was way off.

All I was looking to do is project from underneath and inside a porch out to the side of the screen enclosure. The actual project I was going to put into a plenum rated projector lift that would extend out of the porch ceiling. I measured again and I came up with 27.5' from the projector to the screen.

After looking around I found the ACERPD726W. It is a 3700 Lumen projector and it says they have a throw up to a 40. Using some of the projection calculators out onthe web (www.projectorcentral.com) I came up with having my width at 140" with diagonal at 175". This was setting it to Movie use.

As for the screen, yes I know that was going to be an issue. I was thinking about just getting something like the Draper Luma 2 manual screen and putting a water proof housing around it. 90% of the time it will be retracted. The idea was to use this at night as we sat around the pool and porch.

I appreciate all the info.

A panasonic Ax100 can do a 135" screen from 27.5 feet and should be bright enough to handle it.
