Ricoh has developed a very interesting ultra-short-throw projector when it introduced the PJ WX4130N. Mirrored projection is nothing new, but Ricoh created a fairly compact unit that could be used almost anywhere. In fact, one might say it is more capable than your standard projector since it does not need distance to create a large image. Just 9.6 inches from the wall and you have an 80" diagonal image.
It is fairly bright and quite competitive with units that are of equal size. It produces 2500 lumens of light output. The projector features a resolution of 1280x800 and a max resolution of 1600x1200.
The PJ WX4130N is a single chip DLP projector and has a lamp life of about 3000 hours when projecting in Standard Mode and a lamp life of about 4000 hours when in Economy Mode.
It accepts all the standard inputs you might expect a projector to accept, but HDMI as well. Particularly interesting about this projector is that has both built-in wireless LAN connectivity, and wired LAN connectivity.
