There are two Canon Xeed SX-60 data projectors with a native resolution of 1400 x 1050 pixels and accepting both VGA and DVI input. The blue link takes you to Canon's description of these projectors.

There is also a Stumpfl frame screen measuring 10 feet x 7 foot 6 inches. See http://www.ivojo.co.uk/projection-screen-list.php?t=Folding&r=1-33to1 The screen is usable but the poppers are showing some signs of loosening but it should provide several years of good service.
