“Short-throw projectors have always been favored by schools, because of space constraints and other issues,” she said.
The most extreme of the extreme short-throw projectors
Many projector companies have unveiled their latest lines of ultra short-throw options in recent months, but few—if any—compare to the limited distance needed by the Dell S500wi projector, which hit the market in February.
Projector Central researchers and analysts, during tests with the Dell product, found the S500wi produced a 75-inch diagonal image (63 inches wide) sitting only five inches from the screen.
From just two feet, the projector can create an image measuring 100 inches diagonally, according to Dell.
Dell’s latest ultra short-throw projector, along with many others on the market, doesn’t require the pesky task of calibrating the on-screen image every time the projector is moved, even by a few inches. This can be particularly useful for educators who move projectors around the classroom on carts.
The S500wi, like others in the extreme short-throw category, can create large images from less than a foot away from the screen by reflecting the image off a mirror.
There are, however, new extreme short-throws that avoid the use of mirrors, which experts say can degrade the on-screen image, if only slightly.
Mitsubishi’s WD380U-EST and XD380U-EST extreme short-throw projectors don’t rely on mirrors to cast a large image from a short space, but instead employ specialty lenses introduced by the company in May.
