Hunh, I thought LCoS was dead, but it's taken over LCD? I had to look into this. It does appear there are still quite a few non-LCoS, LCD projectors out there, including those made by Panasonic. Apparently there was an advancement I wasn't aware of in LCD panels which eliminated the appearance of the wires. The wires are still there, but optics are used to magnify the pixel area more than the wires between them. Sort of the opposite of what is done in a digital camera to capture light from a larger area than the small photo-receptors. So LCD isn't dead, but nor is LCoS.

Uuuhhhh.... Ok can I just say that your knowledge base in all this stuff scares me! Thanks. All that was from my head too, except the models of the 3-chip projectors and their prices. I knew they existed, just had to look them up.

The old visible pixels, or "screen door effect" was from LCD projectors which shined the light through a panel. What you were seeing were the wires running to each cell of the matrix. Newer projectors use LCoS (Liquid Crystal on Silicon), these are chips which have the cells touching each other being controlled directly by the chip surface below them, thus no wires.
AFAIK only Sony and JVC make LCoS projectors at least in the sub $10,000 range. Everything in the sub $2,000 range is LCD or DLP. The LCDs have just gotten better at hiding the wires and in Panasonic’s case they use digital processing to eliminate the pixilation. In the past I agree with Alan that DLP had an overall better picture than LCD, however I now feel that LCD is on almost on par with DLP and LCDs usually have better placement flexibility. Rick - What are your intended uses for the projector? In my case features supporting my intended uses helped make me make my projector choice rather than just what reviewers think had the “best” picture. Oops, looks like you caught that before I hit send.

Dean we'll use it primarily for watching movies, the 73" Mitsubishi will stay in the room and the pull down screen will be mounted in front of the TV so that for day to day viewing the TV will be used but I want to be able to pull down the screen for viewing movies and some TV programs with the projector.

I agree, LCD's are pretty much on par in the contrast department these days, unlike the past where DLP's one no contest.. Also, many people still are affected by the "rainbow" affect in DLP's, even with the faster wheels.

I don't see it on smaller screens which don't fill my field of view unless I turn my head and catch them from the corner of my eye. Walking through an electronics store with RP DLPs on both sides of an isle is a bit of a trip though.

I want to see a direct-to-consumer projector maker that stays on the bleeding edge of technology and offers a trade-up program. Can one of you start that company?
