BrightLink 436Wi Interactive WXGA 3LCD Projector is Epson's first short throw interactive model using its latest--which is to say, third generation--interactive technology. That, in turn, means its the first short throw model with the same slick features, and essentially the same capabilities, that you'll find in Epson's current ultra short throw interactive models.
Like Epson's other projectors, the 1280x800 436Wi is built around an LCD engine. Unlike most DLP-based projectors, it lacks support for 3D. However it has the advantage over most DLP projectors of being guaranteed rainbow-free and having matching color brightness and white brightness, with both rated at 3000 lumens. There's also no separate interactive mode to turn on, which means no loss of brightness when you use it interactively.
Some of the more noteworthy interactive features include automatic calibration between the pen and projector, support for working with two pens at once, and a PC-free whiteboard feature, which lets you interact with other image sources besides computers or just use it as a whiteboard with no image source at all. The 436Wi lacks the ultra short throw of Epson's other interactive models, of course, but at $1,490 street, or $1,250 with an education discount, it significantly lowers the price for Epson's more sophisticated interactive extras. You might even consider it a bargain.
