The rainbow effect that may be seen only on 1-chip sequential color projection systems is the result of a rotating color wheel that spins at a rapid speed and displays colors sequentially. Viewers who perceive this blurring or separating of colors may find it annoying and distracting. Projectors powered by 3LCD technology have 3-chips and a solid state optical design so there is no color breakup or rainbow effect.

Smooth, seamless color combined with an unparalleled grayscale range delivers incredible detail to every image displayed by a 3LCD projector. Grayscale is the shades of gray (from black to white) required for greater image depth and detail; it allows greater variation in shadows and brings superior accuracy to color, creating a jaw-dropping, true-to-life visual experience.

LCD technology surrounds us – HDTVs, PDAs, mobile phones, monitors, and more. With over 40 million 3LCD chips shipped worldwide for projection, this powerful and road-tested technology is the optimal way to achieve the sharpest and most beautiful images.

PRESS Release review:

The Epson PowerLite ® W6 projector is Epson's first low-cost WXGA resolution model (16:10 aspect ratio), delivering USB video, VGA video, and HDMI connectivity for high-definition quality video and digital audio from just one cable.

In addition, it offers slideshow functionality via a USB thumb drive or an SD card for easily sharing pictures, a 7W speaker for great sound, and 2,000 lumens white light output and 2,000 lumens color light output for outstanding color performance at this price point. 

The PowerLite W6 also features Epson E-TORL™ lamp technology which allows each projector to achieve more efficiency by projecting more lumens (brightness) per watt.  This technology also allows the lamp to last up to 4000 hours  in economical mode – up to 50 percent longer than competitively priced models.

Convenient Connectivity for Any Projection Environment

Delivering unmatched flexibility and versatility, all three Epson projectors offer Epson's proprietary USB Plug n' Project connectivity for quick projection on-the-spot.  By simply connecting a USB cable, users can begin using the projector immediately.  This means no more hassling with computer function keys to display an image - just plug and project!  In addition, all three projectors offer Direct Power On and Direct Power Off for controlling power from a light switch when the projector is installed.

“With this new class of entry-level projectors, Epson brings presentation ease of use, versatility, and affordability to entrepreneurs, educators and business professionals alike,” said Carrie Brown, product manager, Epson America Inc. “Customers will benefit from the flexibility of USB connectivity combined with industry-leading image quality and performance that are inherent in Epson's award-winning projectors and 3LCD technology.” 
Additional features of the Epson PowerLite W6 includes:

• Epson 3LCD, 3-Chip Technology: Features Epson's latest high-aperture, 3-Chip 3LCD optical engine to deliver amazing color and detail for powerful presentations; 3LCD technology provides true-to-life image quality using a solid-state optical engine that works without a moving color wheel, delivering accurate color registration, and detailed video and data images that are crisp and rainbow-free
• Instant On and Instant Off ® : Enables presenters to be up and running in only five seconds between pressing the “Power” button and the appearance of the start-up screen to avoid delays at the beginning of a presentation; powers down in four seconds enabling presenters to unplug and pack up immediately and safely without a cool-down period
• Easy Picture Adjustment:   Features automatic keystone correction and 1.2x digital zoom (PowerLite 78 and PowerLite W6) for greater positioning flexibility  and projecting  a clear image from short and long throw distances
• A/V Mute Slide: Instantly turns off the sound and images to create a quick pause in the presentation, conserving lamp life and energy; the projector enters A/V Mute mode when the lens cover is closed and returns to normal mode automatically and immediately upon reopening the lens cover.
