Sim2 Lumis Owners Thread - Page 3

post #61 of 1953

There is a significant improvement in black level over the 1080, while maintaining many of the benefits of the other aspects of that projector.

I will be out of the loop on this for about a week, and will have more to report then.

Wanted looks great on my C3X1080.

Anyone know when the lumis will be available without the host. That might reduce the price a few $$. Thanks Greg

At the moment the answer would have to be Never, unfortunately

There will be PJ's that use that technology, but the extra real estate that the host provides in the head unit is certainly needed.

Putting the "processor" in an external box takes more than a board or two out of the box. it also allows extra realestate to add more and more processing to control other aspects of the display. it allows greater lamp, iris, etc control. so thinking that it would be available as the Lumis np (no processor ) is a false hope. it would not be the same machine by any stretch. more likely to hope for is to possibly get sim to offer the processor (image processing part) as a line item for use in other applications.

but just because the processor is in another box does not mean that they could sell the lumis for less money and still have the same image.

Guess that was it for the first round of installs? Did not seem like a large number in the first shipment. Anyone have any idea when the next batch may cross the pond?

By the end of this month (February).

They only rolled out a very small number to start...of which I got the first 2 in the US. More will come end of February but quantities are unknown...hopefully many as there are many waiting!

When someone with a Lumis gets a chance could they please look at how it handles chapter 2 of Letters from Iwo Jima please

Thanks

Thanks

Can't you just sit back and enjoy your relatively new Christie projector without seeking to learn about what may be better??? (HA!)

Thanks to LJG's efforts, our recession will end earlier than otherwise.

If you only knew Steve, The HD6K-M was seconds from being put back in the box, I had the hand truck ready

Any news?

I think he returned it to Sim b/c it only measured 1300 lumens.
post #75 of 1953
I'm wondering if SIM might be looking at the Lumis as a projector for one size screen and another like a new HT 5000 as the units for screen like mine and larger.

Well, if that is the case, they need to change the specs in their brochure, so people are not buying one for bigger screens. My Lumis has gone back for a few reasons, I will post as soon as it returns.

yes thats right.

the brochure say "up to 35000:1 cr"
and the brochure say 1200-3000 ANSI LUMEN!!!

count about 15% less for d 65 than the unit should have still over 2500 ansi
lumen.

with the drop in the corners my unit that i send back today will have just arround ""1300 lumen as i measure always center lumen.

Has there been an unofficial or official response from Sim2 on all these production units?

Some of us have asked, but nothing yet (on my end anyway).

Interesting. For me, this lower # would be good.

It is interesting that we measured the same Lumens, which would lead one to believe that this is not a random error, but a planned modification.

If the specs are to be modified in this way, I would certainly expect a refund, as it is not the projector I ordered.

The lumens could be, but it may have come with lower on/off CR at the same time (at least it seemed to in W. Mayer's case).

post #83 of 1953
Wow, 1200 lumens best case for me would be a disaster with the throw and size screen I'm painting. I would reckon I'd be somewhere around 800 lumens with a 30% reduction for my throw with a new bulb. That's with iris open and high bulb! With a further 30% reduction for bulb wear, we're looking at 560 lumens. Would hate to use stretch for 2.37 ratio at this light output level. Also, if we turned the iris on for best contrast, where would those numbers fall? We just measured an RS20 and it had 700 lumens, exactly what the C3X 1080 we were looking at had, so this projector loses a lot of it's advantage on the larger screens if this is what they're coming in at.

It seems to me like someone at the company should be at least letting their dealers and/or customers know what is happening, or this could turn into Mark Zuckerberg part trois.

edit: Nevermind previous Q, I found what I was looking for...Thanks
post #85 of 1953
"If full black fields have the same luminosity on both projectors it follows that the On-Off of the Lumis is in the 60000-150000:1 range (Lumis white is 3 times brighter than RS20, and a RS20 measures easily between 20000:1 and 50000:1). It also means for black a whopping factor of 18 to 30 is used if native On-Off is 5000:1 as reported. Is all of this the case?"

These numbers correspond with subjective impressions being reported, but they far exceed spec's.

It's truly a mystery how this pj does what it does.

"It is really uncanny how the dynamic black works. Because it is a frame by frame analysis, and source dependent, the better the source, the deeper the blacks get."

How does it react when a very dark scene with no bright areas suddenly gets a small but very bright feature?

You really measured a C3X1080 at 700 lumens? Was the unit defective or were you using it at the end of its zoom range/min bulb/iris on?

Were you and Wolfgang in the same locale, one could figure on it being a particular geographic's shipment having issues, but it looks like that ain't the case.

I have major trouble believing that Sim would do this on purpose, I mean they would surely realize the negative effect, especially on those people who were so blown away by the performance of the first Lumis models?

Optimistically, I would say that the projectors are throttled back because of a firmware glitch, rather than a deliberate mod.

Well, given the tendency of people to think the worst, Sim2 should make some sort of statement through any channel to ease customer's concerns and avoid a PR disaster especially when the groupthink is that perhaps they are dumbing down the unit intentionally.

this last unit was 700 was not defective and had around 1k hours on it. have measured others slightly higher (750-780) that had newish bulbs in different setups.
