Thanks Gary. Looking at your graph:

The red tinted HD145's look very similar to my red. Blue looks the same too but I bet it's very close on every projector since there's never any tinting. The blue comes 100% from the phosphor.

Green on mine is slightly off like you said. Not as good as HD145's. Those HD145's really take you almost exactly bang on don't they?

The green on the RS1 and RS2 is definitely oversaturated and the red is as well although not by as much. I think I read somewhere that pushing the green like that increases contrast. While you can finess the settings to reduce the effect, you're still going to get color tracking errors—neon greens, orange skintones—in some shots. (The rumor is JVC will soon be offering a processor that will correct the problem for the generous price of $3,000). I feel it also has issues with motion blur and image noise in low-light scenes. It's subtle and you can learn to live with it, but it's there.

But to say that it's not perfect doesn't mean that it's not very, very good. Every technology has it's shortcomings and the fact that people are debating whether or not it's better than a high-end CRT projector speaks to the strengths of the RS1/2. Being able to set it up in 10 minutes and start watching movies is no small thing. Not every situation can accomodate a CRT projector and it's great that there are alternatives. All things being equal, I still prefer the look of CRT particularly if you're still watching any SD material. (Not everything I want to watch is on Blu-ray yet.)

Regarding digital projectors with built in CMS... I know someone who recently traded their RS1 for a Sony VW60 (Black Pearl) because the color tracking on the RS1 bothered him. I went to see it once he installed and calibrated it. The difference was subtle but noticeable and you weren't constantly second-guessing the colors on-screen. (The CRT equivalent I suppose is endlessly fretting about convergence and corner focus.) What was interesting though was that he told me he had to recalibrate the VW60 every 40 hours or so since he was still breaking in the lamp. In general the lamps lose up to half their brightness in the first few hundred hours and then stablize. Once it does stabilize, he shouldn't have to recalibrate it as often, but I was a little surprised that it wasn't a one-and-done kind of deal.

Last weekend I was at the Montreal Hi-FI show, and I took in a demo on the new Dreamvision model, msrp at $ 25000.00. The rep stated that it was a JVC 3 chip lcos techonology. They played The Kingdom in HD DVD from a Pioneer player displaying it at 2:35 to 1 ratio.
The image was fantastic but then I realized that I have this same image in my basement emanating from my Marquee 8000.
Separately all digital projectors look awesome when viewed by themselves , it is only when you compare them side by side that you see the differences.

Why would anyone not bother just buying color filters to get better starting points on the primaries, and neutral density filters to lower the black level? I mean, if you are going to go digital then you should be trying to get the most out of it using the biggest bang for the littlest buck.

Scott: Interesting. I suppose if you could put something in front of a digital to try and pull all 3 primaries inwards.

Gary: Yes, that RS1 is pretty off in the green. You're right that it's no wonder that they look 'cartoony'.
