Anyway, the FPD2185W also has a integrated Faroudja chip for enhanced video processing, a built-in 4 port USB hub, a 1000:1 contrast ratio, 178 degree viewing angle (both vertical and horizontal), and an 8ms pixel response time.
The key is a filter that sits in front of the projector to block vertical regions of the screen, meaning that each one of your eyes sees a slightly different picture based on the angle at which it views the screen.
