View Full Version : Changed My Opinion of LCOS...

Up until now I've been in the DLP camp. I've seen a few LCOS projectors and wasn't impressed. Until now.

One of the local Magnolia stores replaced the Sharp 12K in their projection room with a Pearl. All of the previous Pearls I've seen have been poorly set up, but this one was different. It was accurately aligned with the screen and not tilted (so no keystone correction was needed), had been calibrated to ISF standards, was fed with a Toshiba XA2 HD-DVD player (King Kong), and projected on a Stewart Firehawk (but not SST) screen.

This made a huge difference in the PQ compared to that I've seen on other Pearls. The image was slightlyless sharp than it was on the Sharp DLP they previously had in the room, but I had to get very close to the screen to see it. From normal viewing distance, sharpness seemed to be more than adequate. Brightness was almost too bright with the Pearl in low lamp mode and the iris set to Auto 1.

I came away from this demo with a new respect for proper set up and how it can affect the screen image. I'm completely at a loss as to why vendors selling high-end projectors often have them poorly installed and calibrated and then expect to sell them to anyone with a reasonably critical eye.

I'd almost ruled out LCOS entirely in favor of DLP, but now I'm even more eager to see an RS1 in action and may go with an LCOS machine. Even the Pearl, which hasn't gotten a whole lot of lovin' in this forum recently with all the talk about the RS1, may end up in my theater if the RS1 isn't noticeably better than the Pearl I saw this weekend.

Just wait till they combine LCOS with a 3 laser light engine. You ain't seen nothin yet.

I live in the Bay Area... where is this Magnolia located?

If you can tolerate the Auto2 setting on the Pearl I suggest running that setting all the time.

reio,

is there a reason behind this? What does it do that Auto 1 doesn't?
Thanks,
scott

It's funny how people see things differently. My viewing of the Pearl made me start to second guess my purchase of the RS1! :eek:

But in fairness, it was not very well set up.

The better ANSI from DLP can't match the improved shadow detail performance of the best LCOS.Shadow detail is a function of a good gamma curve and is not correlated with any particular projection technology in any way that I'm aware of.

Magnolia is a section in select Best Buys. Put your zipcode into the store locater on:

I beleive he wants to know the specific Magnolia store since the OP said that particular Pearl was set up properly.

I agree - I've seen a local HDTV shop with a dedicated theater room (full black curtains on 2 walls) with a Firehawk SST, calibrated Ruby, and dimmable ambient lighting (slowly dims to black) that was probably one of the first impressive HT displays I've seen in a shop. Until then, I always found them inferior to well setup homes with dedicated theater rooms.

The Ruby really impressed in this setup.

Hi Jerry,
I've also been to the Dublin location, and found the Pearl to look very good. One of the salespersons in particular is very knowledgeable, and I believe frequents this forum.
I've invited him over, once I receive my RS-1 (third wave), so that he can evaluate it and help me to optimize it. If you would like, I'd be happy to invite you over as well. I reside in Pleasanton.

Take care,
J.
