So with the previous models there was a significant difference as I indicated above. So you feel you are getting a strong performance gain for your money as well as the CMS (which worked).

You are feeling ripped off for the 50! What about the 60?!

So I am ready to tackle the RS50 calibration now that I have gotten some solid reps and results in...I am wondering where this new firmware is that is suppose to fix the CMS? I saw 1.3 posted, when did that happen? I was on 1.2 as far as I knew...everyone must be enjoying their PJs too much to care anymore

The screen size is irrelevant, but the zoom position is relevant. The zoom position is mentioned in the table. As the lens is identical between X3/X7/X9, that would not explain any differential between models.

I didn't try with profile off since it would have been academic -- I would have never watched movies with that setting.

Here is the basic setup:

RS-50
@ 17'10" throw, 1 hour on bulb
high lamp, thx mode, completely open iris: 540 lumens
high lamp, any mode with additional color filter: 398 lumens

RS40
exactly the same setup and light meter
high lamp, natural D65k mode, completely open iris: 722 lumens

540 -> 722 is a 38% jump.

I'm at 70 hours now with the RS40 so this weekend I'll check for dimming.

Can't do any calibrations to it though (yet!)

Your review is tremendous. It nicely details the differences -- Thank-you!!

I'll be more than happy to email you the Excel Spreadsheet if you want -- PM me with your email address if you want it.

Mine dimmed @ 150 hours as well about 30%+ and around 40% by 270 hours. I have a replacement, but not going to use it just yet. I want to see how much dimmer this will get, or hopefully has leveled off considered I only have 360 D65 lumens.

It's a shame the quality of this no-name lamp is becoming such an issue for the 2011 models. it's complete luck if you get one that doesn't die early or start dimming significantly in a short period of time.

Nice carpeting too....different.

I am selling off my older Mitsubishi HC5500 and a number of factory lamps I had hoarded. That is funny money for either the lumigen Mini 3D or the Mitsubishi HC9000. I need to know more about it from people who are familar with the level of ghosting on the JVC's to say it's better/worse/even.

900 and 1100 lumens in 3D mode + my 2.8HP would be kiiller in 3D. I almost thought of picking up the Sharp, but the mounting requirements is downright silly (12+ inches ABOVE the screen) and would be a deal breaker with my HP screen.

Yes, they dramatically improved CR for their "low end" model while CR for the middle model is only slightly improved.

Cine4homes contrast data shows that the max contrast spec is much like the lumen spec: it's achievable only under specific conditions that one would never use for actual viewing. In actual use the differences are less dramatic than the advertised numbers would indicate. Throw in the fact that the lower lumen output of the 50 & 60's means the iris won't be closed as much (compared to a 40 putting the same fl on screen) and those differences narrow even moreso.

That certainly doesn't help the value of the RS50/60 but to me the more serious issues with them are the impaired CMS and virtually useless Gamma controls. I think many of us decided on the 50 instead of the 40 because of the CMS, and increased CR spec's (of course the lamp iris, Cinema filter, VGA input and various color profiles also favor the 50 & 60 but I think everyone expected a working CMS and gamma controls). Releasing the mid and high end models with an impaired CMS and useless gamma controls devalues the machines and virtually mitigates the reasons for buying the 50. The lower lumen output is salt to the wounds. Ditto with the perfect gamma setting behavior of the 40. I continue to see virtually no reason to purchase a 50 when a 40/Mini3D combo totally mitigates CMS & Gamma issues and is less expensive and more flexible to boot. The improved CR of the 50 would likely never be missed (or even noticed).

So yeah, 50 owners paid a lot more for very little in return: Don't you feel ripped/boned off too?

I didn't mind the price difference when I thought I was getting a better projector -- one with a properly functioning CMS and one with usable gamma controls. To charge so much for these broken features while advertising the new 7 axis CMS and 50% brighter bullcrap reeks of a "haha fooled ya and screwed ya attitude". It's painfully obvious we cannot trust their advertising. Like I said earlier, they really must have huge corporate stones to pass this crap off as an upgrade. I do hope somebody sues their asses.

How are you coming along on getting a 40 (or have you decided to try the Mits)? Think of this dilemma for those of us use AT screens w/ ~ a 1.0 (or less!) gain!?
