Can the projector be 20 ft away from the screen?

What kind of projector? What kind of Screen? All of these things are vitally important.

Hello, in the directions to my sharp projector it tells me approx. how large the image will be with different length throws and it lists up to 58.4ft. minimum throw and on that catagory it doesn't list a maximum which means to me that you can put the thing 70 feet away and just zoom way in and still get a great picture, I had(I use past tense because my projector fried in a recent electrical storm, and I am now dealing with the insurance company) a 15ft throw and it made the image 100" and a GREAT picture with progressive scan and a good component video cable and a complementing screen it is very enjoyable as long as your room isn't too bright- so there are a lot of factors with front projectors to ensure truly good results. FWIW the 58.4 ft minmum indicates a 500in image that it will produce :) I don't think 20ft is too far by any means just means you'll have potential for a HUGE image.

To Ksales, I don't have a prjector or screen. I'm trying to see if a projector is a feasible idea for my room.
