Panasonic PT-AE7000
The PT-AE7000 is Panasonic’s first 3D home theater
projector. It uses a 200W “Red-Rich” lamp capable of a brightness of
2,000 lumens. It also claims a 300,000:1 contrast ratio. The full HD LCD
panels are designed for 480Hz processing - this results in a brighter
3D image and reduced crosstalk. It even uses the double refraction
property of crystals to arrange pixels to minimize screendoor effect.

Epson EH-TW8000
The 3LCD-based EH-TW8000’s 2,400-lumen brightness rating
makes it the world’s brightest 3D home theater projector. Using an image
engine with a 480Hz refresh rate, the projector also has a manual lens
shift mode with a wide lens shift range; the latter gives you more
installation flexibility. A frame interpolation technology is used to
reduce image blurring. It's also capable of 2D to 3D conversion
