it does?

and closing down the irises dont seem to affect 1% and over.
Yes it does.

Nigel didn't measure iris closed. I've seen multiple measurements when that projector came out in this forum and it was hitting 100k or over actually in a couple instances.

gotcha, kris' measurement was 50k iris closed so wasnt sure. whats the light output with the iris closed?

Pretty dim probably 250lm, why does it matter?

id like to see the 0.1%, 0.25%, and 0.5%adl dynamic measurements for the nx & 1080p models iris open and iris closed

Sorry....i dont think so...
of course it will at some point. I am not talking about the RS3000. I was talking about a future replacement. Native on the RS4500 iris open is around 10,000:1. Native iris open on the RS3000 is around 30,000:1. I was talking about one of the future generations, when RS3000 eventually goes to laser. You know at some point, native iris open will get close to 50,000:1.

eventually they may be able to translate that contrast to 1% adl + as well, now that would be something... who cares about transit times at 50,000:1 at 1% adl. When you consider that there are peak light output limits for larger screens, contrast becomes king.
Keeping peak luminance values down isn't just about keeping black levels respectable.

There is some useful info that was presented at the SMPTE conference with respect to the issues of comfort on large high contrast displays. This is particularly important in high end HT settings where rooms can be perfectly black without fear of construction codes getting in the way with safety lighting, fire escape signage, etc...

It is even more important as we are entering a new dawn of extremely high native contrast projection making its way into some exclusive homes (like the Christie Eclipse); and in the home environment doubly so as we don't have the benefit of specially curated DV 100nit grades for Dolby CInema. If you have consumer content being tone mapped automatically there is a high chance of viewer annoyance as the small screen grade + tone mapping results in a very bright result on screen.

So you measured 850:1 ANSI in your room did you? Can you run your contrast measurement methdology past us?
i put the meter in the white, i put the meter in the black i divide numbers. 272lux white 0.32lux black. These measurements were all done by professional reviewers and other owners a decade ago I don't know what's being contested. The Samsung A900B measured 900+. My only error was the actual measured contrast in low power as I recalled a measurement that didn't include the screen gain.

btw, all this hub bub over what i report for the mico, but mike says "nx9 native 100k:1" i say "really?" you say "'yes really, well with the iris closed", i say "at what light output?", u say "why does that matter, 250 lumens."

So I think maybe it does matter more saying the nx9 does 100k but omitting that thats at 250 lumens, moreso than my 1% dynamic being in the 10-15k range. good talk. [-__- ]

So when I talk about my projector should I say that it does almost half a million:1 contrast and thats it? Because thats technically true. No, I would actually tell you 3 things, I would say its 43k:1 iris open, 160k iris -15 iris and 430k dynamic, each of those scenarios has its uses and all are completely valid, I use -10 iris for SDR, my projector is pretty bright, that gives me 50 nits, thats about 90-100k:1 right there.

its not a useless number. Mike is not out of place saying that because its a completely real scenario. As such, why does it matter what lumens it is? 250 lumens is enough for people with decent gain screens to actually get 50 nits for SDR, its not out of place. I reckon Zombie actually could probably do it, but I think he likes a bright image.

What would NOT be correct is to say that the projector only does 25k:1, thats completely false and ignoring that a dude could just use a couple clicks on the iris and potentially be up at 50k, 80k, 100k...

lol after posts and posts of "2000 lumens or bust" suddenly 250 lumens is fine, ok dude.

The RS3000 has 100,000:1 native contrast.
LOL WTF? It's been measured several times and is never anywhere near this. Sometimes I think we need to ditch the marketing talk and discuss reality.

and still only 8,000:1 at 1% adl on 250 lumens
No, why would it be 8k at 250 lumens?

My JVC does that at full brightness.

Like I said, I think you are having trouble with what is being discussed here.

I guess this guy has a unicorn then? He does have a Klein meter.

did you do this in your room stacked with your Mico at the same time?
i dont understand how thats relevant when i have an oled in the house, are you going to tell me that dilas 100nits white to 0.01 nits black at 1% adl is comparable to oleds pure black? Every time I mention the color performance, pixel response, lack of a color wheel, high ansi contrast, single panel, and uniformity makes for high contrast, highly detailed, dimensional video, and... repeating myself... qualities that lcos and even oled dont possess, the only response is "but my on/off and big screen".

you seem a little aggravated with my repeating myself for different audiences, but it seems ive yet to properly impress upon you the superior video quality of this specific projector or optical engine. If you get an lsp9t youll have a better idea, just turn off xpr, double its native contrast, swap out a $4,000 lens, and use madvrs dtm+the 3dlut and youll have an idea.

and look im sorry if me saying i prefer the mico to your jvc and quantifying the technological differences between them in an unbiased and objective manner got under your skin. for what its worth if you look at the big picture dmds are used in everything from pico projectors to pinnacle video to terahertz imaging systems, meanwhile there are a couple new lcos projectors a year or every other year with modest improvements, and it turns out the best use for lcos is fourier transform light steering in a dlp projector. Eventually dlp will surplant lcos at our price bracket in the one aspect that lcos has superior image capability, so just enjoy the look of polarized liquid crystal and dont worry about my personal preferences for objectively superior video performance in every aspect except for lowest adl contrast ratio. Just a friendly jab, right?

let me just get this out of the way, because frequently persons who express interest in dlp(or oled it seems) are wittled down and all the forum is left with is a jvc echo chamber. you personally have done this too me a couple times now, youll contradict me when i say the mico has objectively superior pixel delineation and that ansi contrast has an observable impact on image quality, twist my intent of posting a photo about xpr to slandering jvc, say the single panel sharpness and higher ansi contrast of the panasonic are noticeable compared to the jvcs, say the eclipse cant be used as a reference to the mico but than say the panasonic looks comparable to the eclispe... not so friendly, just confusing. on this forum its observable over and over this type of gaslighting and condescending false contradictions, and it baits people into over reacting and leaving the forum or getting banned. We're not friends, i dont know you, so when you say something slanderous thats all it comes across as. look at the people hanging out here advising people on the ins and outs of projection day after day, they repeat themselves constantly, its how forums work, so if you take issue with me expressing my elation with a singular unique projectors performance for as many people as possible, just put me on ignore, because I have no intent of silencing or stifling myself.
all and all it should be obvious that if the projector doesnt provide the light output for your desired screen size its not worth considering, but its worthwhile to me to express the fidelity of this machine to persons interested and willing to compensate image size to accommodate it, or at least what to look for or hope for in the future of projection.
