My point in posting was to find out if the new unit has this issue fixed or not, not to troubleshoot something that has already been through the troubleshooting process.......
I was writing to JeffMac even though I posted right after you. Again, I work with Sim and am aware of the issues. I am simply suggesting to Jeff one of the things that should be tested if he has not already done so.

I am not saying it is not the Sim but as part of troubleshooting I would recommend trying a new HDMI cable and seeing if the problem persists. I have encountered some very unusual intermittent issues due to HDMI cables.

I've already tried two different HDMI cables and both made no difference. Thanks for the suggestion though.

BTW: The red sparklies are only produced at 1080p60.

Had this EXACT problem with my (UK Supplied) C3X 1080 - Red sparkles appear in dark areas with increasing frequency until the picture was unwatchable...

It was diagnised with a single phone call then returned to Sim by my (superb) dealer, and the problem fixed (small modification to a single component I'm told) - in all it was away for only 4 days - so far I've been delighted with the customer service.

Since then this problem has never resurfaced.

I get the red sparklies using my cable box with the C3X1080. I thought it might be the cable box, but I just replaced the box and grounded the line and the problem is still there. When I switch the cable to the other HDMI input on the C3X1080, the red sparklies are less and look very different (one HDMI input behaves much worse than the other...). I'm supposed to get a firmware update soon from AV Science, so I'm keeping my fingers crossed that all of the 1080p and 1080i issues are solved finally....

Depends on if yours was an early production model. I had a tech from Sim and the local rep at my home. They spent the whole day here and then came to the wrong conclusion that it was the Blu-ray player.

Not seeing it makes it difficult to assess, but if it IS the red dots/sparklies that has been reported by others, then the firmware will not help. As I indicated previously, and as posted above, the unit needs to be modified. It is a VERY minor fix to the board. I guess try the firmware and if that doesn't work, make plans to get it back to Sim2. You shouldn't have to live with that issue.

Thanks for the help Jim. That was very nice of you.

The problem is that I started with a Sim2 C3X1080 almost a year ago. When the installers came we found that it was producing red sparklies and red lines on the side. The installers spent more than a day trying to figure out if it was the projector, the hdmi cables or the Denon blu-ray player. They went back and forth with all the manufactures and Sim kept blaming everyone else for the problem. Finally, we got them to admit that it was the pj and my dealer ended up paying the overnight FedEx charges so we could get the job done on time.
The second projector lasted about twenty hours until the reds completely disappeared. Sometimes it would work and sometimes it did not. At our expense the projector had to be taken down and a new one installed.
The third projector worked fine for awhile and then started producing red sparklies at about the 90 minute point. Once again Sim was contacted and they sent a tech from southern California to install a new one if needed. They spent a day at my house and came to the conclusion it was the blu-ray player. I found this hard to believe since the Sim had already produced red sparklies in previous projectors. So the dealer ordered a new Denon 3800. After the new Denon was installed the same problem existed and I am now convinced it is the projector.
I think I’ve been more than fair to Sim and certainly have given them enough chances. As I said almost a year has gone by and I really haven’t had a chance to even enjoy a movie. I’m too nervous waiting to see what will go wrong now. It wasn’t a whole lot of fun when all my relatives on Thanksgiving where pointing to the screen and asking what all those red lines were – including a ten year old.
Now that they are coming out with a new model I feel like I paid top dollar for a pj that is now way down in value. At this point I think I’d just like to get my money back and move on to another manufacture.

Oh, I also paid for two calibrations ($1200.00) which are now worthless.

Jeff, when you connect HDMI straight from the Blu Ray player to the projector, how long is the cable, what cable brand and type is it (is it HDMI 1.3a certified), and do you still get the red sparklies?????? Also, if your HDMI cable is installed in wall, funny bends can do sparkly things. That's why you test it out with a direct as short as possible HDMI line from Blu Ray player to projector. Now mebbe all the folks who tested your system to try to find the problem did all this??? I( do not blame you for being annoyed.

Yes, I tested it four times with two different hdmi cables. The cable does go straight from the player to the projector. There is nothing in-between. Also the problem doesn't start until about 60-90 minutes into viewing so I'm thinking heat has something to do with it.

This is a known issue with some internal component failure with the C3X 1080 that has a simple board fix as JLG mentioned. Send it to FL is my vote and it will be AOK. the C3X is an awesome projector, new models IMO do not change that. But it should be right and Sim2 customer service in FL is responsive and will most certainly support you.

How long is your HDMI run BTW?

My guess is it uses 62.5/125 µm fiber (10GBASE-LRM or 10GBASE-LX4), since it can go up to 220 meters and 10GBit/sec per fiber.

Yes, so the only way would be 10Gb/sec per fiber (on Sim2), and not only 1Gb/sec, like 10GBASE-LRM or 10GBASE-LX4.

Btw, HD-SDI is almost 3Gbit/sec (1080p) and way better than HDMI.

35000:1 CR and 3000 ANSI Lumens!! :)

http://www.dezignare.com/whatshot/08/dec/05.SIM2.htmlYou mentioned something about maybe wanting a darker screen material and I think that could be a good fit with this one, although it partially depends on the range for the manual iris and how well it works with other things. I'll be really interested to hear how well the dynamic system works overall and how it interacts with the manual iris. For instance, there are situations where it could be pretty useful if a person could close the manual iris down and still get high on/off CR with the dynamic system (dynamic iris and lamp) for some material (like movies in the dark), then open up the manual iris for some other material (like football or lights on viewing). Closing the manual iris down could also give a better starting point for native on/off CR for the dynamic system, so a brighter screen might have an advantage there, but an open manual iris might provide more on/off CR with the dynamic system. A manual iris can be pretty useful by itself (as I told somebody from SIM2 at their CEDIA press conference a couple of years ago), so even people who don't want to use the dynamic system could get something useful here.

For Art's screen he would probably have to have the manual iris mostly open, but this could be a good projector for him if he can get good convergence (his current SIM2 HT5000 has great convergence in his setup) and he ends up liking their DI system. I wonder if SIM2 will put a DI in a projector like the HT5000.

I think you may have asked the right question. The big deal is I don't want to give up what I've got to gain in another parameter. A dual lamp 5000 with the contrast things in this one would be up my alley.

Darin, I don't see it being a substitute for an HT5000, let alone an upgrade, nor do Sim2. I also don't see it being suitable for a user of a 14ft screen who requires 20fl.

Remember its 3000 ANSI lumen, that will probably translate to around 1300/1400 D65 lumen. The current C3X1080 is rated at 2500 ANSI lumen, and provides around 1100 D65. Obviously the number could be made higher if contrast were allowed to be traded.

The HT5000 optics are at a very much higher level too. The straight through arrangement, rather than an alpha path engine, as well as the constant aperture zoom mean that the HT5000 will loose far less light than its smaller sibling.

I do think this new machine could be a real killer.

I would also like to see a good DI in the HT5k. I'd really like to see a dual lamp 5k with a DI and a manual iris that would let you drop the light to that of the single lamp unit

Im sure it will be a killer machine. I'll be replacing 2 C3X1080s if it delivers.

Regarding lumens, you will be able to get more than that for non critical viewing like sports. Ive seen the old C3X push out well over 1500. Your zoom position will have a significant effect with all C3X versions.

I see its not that much higher priced that the current C3X1080.

12-13-08, 10:33 PM
Darin, I don't see it being a substitute for an HT5000, let alone an upgrade, nor do Sim2.It doesn't surprise me that they don't, but just like a lot of things, when one projector is better in one area and a 2nd is better in another area, people have to choose what is more important to them and may rank things differently than even the manufacturer. I know they aren't in the same league as SIM2, but as an example, Da-Lite recommends against using their High Power material for home theater since they consider some of their other materials better, yet many people get better images by using the HP over what Da-Lite does recommend (making sure we setup to use the screen properly). I think in this case it will partially come down to how much the differences are in convergence (including across the whole screen where I think the C3X is going to be less consistent for reasons you mentioned in your post) compared to how well the dynamic system works and how much a person values each of those things (and the requirements of their setup of course).
I also don't see it being suitable for a user of a 14ft screen who requires 20fl.I'm not sure that Art requires 20fl. I know he wants it, but he wants other stuff too. As we've talked about many times, we have to pick our poison as no one projector beats all others in every area. Much like when he went from the G90s to the HT5000. He knew he was giving up on/off CR, but was gaining other things. So, he didn't really require the very high on/off CR even though he valued it highly. In this case I don't know what it would take in other areas for him to give up those high ft-lamberts for 2.35:1 movies, but wouldn't surprise me if he would be willing to give up some for enough gain elsewhere.
Remember its 3000 ANSI lumen, that will probably translate to around 1300/1400 D65 lumen. The current C3X1080 is rated at 2500 ANSI lumen, and provides around 1100 D65.From what I've seen it looks like the current projector has a 250W lamp and I thought I heard that the new projector had a 300W lamp. Just that factor would take the 1100 up to your range (a little over 1300) if everything else was equal, but I don't know about other changes. Do you know if the opening in the lens with the manual iris open will be different than the effective opening with the current C3X1080?
Obviously the number could be made higher if contrast were allowed to be traded.A dynamic system can help here, but I don't know enough about their system. With some other dynamic systems the highest CR is also the highest lumens, so somewhat different than things were before dynamic systems. That doesn't look like the case here, but the dynamic system could make having the lens be as open as possible (for more lumens) be more acceptable.

As far as Art's system, when he is at 14' wide he is using an anamorphic lens that helps get more light into the screen area. When he is watching 1.78:1 or 1.85:1 material he is more like 10 and a half feet wide. In that case 1300 lumens with his screen, which is around 1.2 gain, would be about 24 ft-lamberts for the brightest spot. Without the anamorphic lens the 14' wide case would be about 14 ft-lamberts, but if the anamorphic lens increases that 20% it would be about 17 ft-lamberts. That is of course with the bulb new enough to give 1300 lumens.

For 16:9 stuff I think Art could be fine for ft-lamberts with this new C3X. For 2.35:1 it kind of depends on what changes they've made (like was the lens shut down some for the current C3X1080 to help CR partially because they didn't have a dynamic system), but you could definitely be right about the lumens being too much of a problem for Art there.
The HT5000 optics are at a very much higher level too. The straight through arrangement, rather than an alpha path engine ...Yep. That is one reason why I wonder if Art would still be happier with his HT5000 even with better on/off CR from this new C3X (even if they do a great job with the dynamic system), or whether that would tip things toward this new one for him. Between the better on/off CR of this new C3X and the better optics of the HT5000 I'm not sure which Art would pick, but the lumens are another difference to consider, like you said.

Obviously the best case for him for SIM2 would be if they come out with a similar improvement to the HT5000, but I would still love to have him get to compare this new C3X to his HT5000 and tell us what he thought. And I think this new C3X vs the new Christie LJG got would be interesting too at a screen size the C3X could support well.

Is that 1100 on low lamp or high lamp? In this case the article says that part of the high CR for the new one is from a dimmable lamp and I think I heard that the lamp was being run dynamically, so high lamp is what should provide both the highest lumens and the highest on/off CR (although dynamic), unless the range for using the lamp dynamically is as big when on low as when on high.

Older DI implementations would cause lower fL on masked down scope content because of the black bars being factored into the overall scene brightness. Do modern DI processors work on the active picture area or still look at the whole pixel grid?

I will back to back the new machine and an HT5k properly as soon as the new one is released. A number of people have already seen it, comments being favorable.

The fact that this machine is a HOST as well as a new internal chassis design should help mitigate some of the current issues with the 1080 that are footprint induced. The chip alignment is said the be better, but I never had an issue anyway. The MC adjustment was added fairly quickly and seems to do a good job.

The HT5k platform will not be standing still. I'm willing to bet my left nut that if the new machine works well, we will see an HT5k implementation. The 5k has been king of the domestic sector PJs for 2 years, so its due a makeover.

As you say, comparing at screen sizes the new machine can support would be very interesting indeed.

I haven't heard of any where the user sets the aspect ratio of the source for the DI, so they would have to sense it.

In a case like Art's he is using the full panel for 2.35:1 because he is using an anamorphic lens, so the above issue doesn't come into play.

So, in essence, with a scope movie, the average of the entire panel is looked at, and the iris, and bulb modulated based on that average, so a bright image in a scope movie would be dimmed down 25%?

This would end up being problematic for me, since I am going with a constant area set up, with no lens, and my scope movies will be zoomed to fill the larger screen, while my 16x9 content will use the whole panel. I guess I would have to turn it off then.

Anyone have a guess as to what the CR would be, without DB engaged?

I do not think full panel vs zoomed should come into play regarding the DI performance

12-14-08, 12:45 PM
Well... as I understand it, a scope film would only take up the center portion of the panel. If you are doing constant height, you use a scaler to expand the scope source to fill the panel (vertical stretch) and then a lens to restore the proper shape, so the entire panel is used in that type of set up.

If you are just using a 16:9 screen, or a constant area set up, when watching 16:9 the panel is full, and watching scope there are black bars on top and bottom. The Dynamic Black system software then analyzes the average brightness of the entire panel, which for scope would be 25% black bars, even if you zoom it in to fill more of a 2.05:1 screen, so the software would think that 25% of the image is black, even if the scene is a sunny beach. Then it would clamp down the iris, and/or dim the bulb, thinking the scene is darker than it actually is.

Am I missing something here?

How hard would it be for Sim2 to add something to the software (say a 2.35:1 mode) that would ignore the top and bottom parts of the panel when calculating the modulation of the DB system?

The Dynamic Black system software then analyzes the average brightness of the entire panel, which for scope would be 25% black bars, even if you zoom it in to fill more of a 2.05:1 screen, so the software would think that 25% of the image is black, even if the scene is a sunny beach. Then it would clamp down the iris, and/or dim the bulb, thinking the scene is darker than it actually is.

Am I missing something here?

How hard would it be for Sim2 to add something to the software (say a 2.35:1 mode) that would ignore the top and bottom parts of the panel when calculating the modulation of the DB system?

OK, so what you are all talking about is a software based deal. My mistake! :o Stupid posts removed!

The software drives the hardware, which in this case is probably a dynamic iris, and variable bulb output.

Then it would clamp down the iris, and/or dim the bulb, thinking the scene is darker than it actually is.

Am I missing something here?While it would see the image as darker than it is, what it does with that information depends on the algorithms and I don't think most DI projectors would close down the iris at all for all white in the 2.35:1 area and then black bars. For the brightest 2.35:1 images the iris would probably be either open or very close to open and then you could think of this as basically being like using more aggressive DI algorithms. The effect probably isn't that large, but if they wanted to do something they would likely have to know whether the bars were masked or not (like they are in your case). If the bars aren't masked then it makes a lot of sense to include them in the algorithm since having those bars there affects what the user sees as black.

I think you should just try it and see if you like the way the DI works for 1.78:1 and 1.85:1 content and also whether you like the way it works for 2.35:1 content, then decide for each based on what you see. I doubt you'll notice enough difference from the algorithms including the black bars in analyzing the images (assuming they do) to make you go from preferring the DI on to preferring it off.

I haven't checked the cable box issue to see if it is still occurring, but no it still won't be the end of all my issues; I still have the screen moire to deal with. I'm having a hard time finding the best angle for the replacement AT screen. I'm going to spend some extra time on it this weekend. So far it seems to be in the range of 12 to 14 degrees using the materials they sent me set up the way they instructed.

Thankfully it may be the end of my PJ issues. Of course, if I want to upgrade, which I might want to do, then it doesn't make sense to work out the moire issues on this screen until I replace the projector, since the results may be different with a different PJ.

I am getting darn close to being completely finished with the equipment issues. Then I have some remote programming I need to fix up on the MX-3000. Right now I just have it set up to do the bare essentials for each piece of equipment, and no macros programmed into it yet.

I'm not sure how good I can get the screen to look without having to use a few pushes of the focus button in order to smear the pixels enough not to moire...

Right now it has to be way too unfocused to achieve a decent result, but I think with the new angle measurements I took using the material and compass that Stewartscreen sent me, it might be something I could live with, though I would rather have it completely focused considering the price of the PJ and the screen!

Well... after hearing all the rave reviews from people who viewed the RS20 at the shows, I was probably expecting too much. It is probably better than anything under 10K, but still falls down on ANSI (Image is 2 Dimensional) and the colors are not very accurate (probably will improve with tweaking). The image is also on the soft side, although an improvement over the RS1. I also still see the same noise in the image I see with my RS1. The image still looks a little like a cartoon compared to the C3X. Very nice black level though. :)

I'm using Stewart Screen Microperf X2. They sent me materials to try and find the optimal hole-punch angle. They told me the issue is that once you introduce more than one chip into a DLP projector, it is hard to standardize the hole punch angles for a whole series of projectors due to variations in convergence between each projector.

They said some other three chip technologies are not as hard as DLP in this respect, such as SXRD. Once I find the optimal angle and get the new screen, it looks like I will still need to defocus the projector slightly. I haven't found any angle yet where I don't see moire at all, but if I minimize it enough, the defocus amount will be small enough to be unnoticeable.

I don't see what is so strange about it? Stewart Screen told me it happens because of convergence issues. I just assumed it happens all the time, since they didn't act terribly surprised.

If the angle the holes are punched at do not line up correctly for the specific projector in question, the moire occurs. So they sent me a kit they use so I could find the best angle for them... The kit is a piece of board with the pattern on it and a compass to measure the angle that looks the best. Sadly, in some situations it can'tbe 100% perfect, so they offered alternative options, such as microperfing only a small section of the screen near the speakers or refunding money and making it non micro-perfed (not an option for me since I have a full size center channel), etc.

I have no reason to think anything suspicious is going on...

One thing that was mentioned to me, is that many installers will de-focus the DLP PJ if there is moire present until the installer finds the right setting where the moire disappears (I forget what the installer terminology is for this). I've played around with this myself and it does work, but with the current screen I am using it has to be de-focused too much; the picture gets too soft. I believe I can be satisfied with the better angle I am finding using the instruments Stewart Screen sent me and the smaller amount of de-focus that would be required with that better angle.

I've accepted that it won't be perfect with an AT screen, but I do expect improvement over the current issues. Playing with the instruments Stewart Screen has sent me does show that a decent improvement can be made with a different angle cut to the microperfs. I still want to play with it more just in case. So far I've only played around with it using a white projected image. I want to try it with some other light colors just to see if anything new is revealed. I won't be able to do this until after the New Year though...

Q,

I have to fundamentally disagree with that philosophy for a number reasons........

1. The aim of a PJ is not to impart a given look, but to reproduce the source as accurately and transparently as possible. A good pj must be source agnostic. Not all source material is film, see #3

2. Film can be razor sharp as well as soft. A fresh print that of a film that was meant to be sharp will be very sharp,

3. Almost everything you see at the cinema on film has been through a 4k or 2k Digital Intermediate process no matter if it were originally captured on film. This means you are watching a digital image transferred back to film.


Some cinema based DCI machines, dlp and otherwise, have a defocus applied but the reasons for that are certainly NOT associated with achieving a certain look. Its to compensate for technical limitations.

The side masking panels of the SMX screens would indeed appear to be a lighter shade than the rest of the screen border. Strange, I wonder why SMX went with this design choice?

Hi Sean,

I don't want to take this thread off topic but since this was mentioned a few times in here and in other threads, I thought it would be best to explain.

When the lights are off in the theater and the movie is playing, our masks are the same color as our black hole velvet frame finish. When there are full lights on (like in the video you posted) the mask panels will be lighter.

Here is one of Peters (Cineramax) videos demonstrating our ProMask system with ambient lights on. ProMask Video (http://www.youtube.com/watch?v=tX8Da_AuOkA)

Explanation:
The reason our AT mask panels are lighter than the rest of the frame is due to a couple of reasons. First, the black velvet upholstered finish we use on our frames and mask bars is unlike anything any other manufacturer uses. The other masking systems on the market are finished with a black flock which is an imitation velvet. This flock they use reflects much more light back than the velvet we use due to its low pile height, so their entire frame is a lighter black than our frame is.

Here is a side by side shot comparing our velvet against the black flock trim another major manufacture uses. This shot was done with both samples side by side at the same time with a flash from a camera hitting them.

The SmX velvet finish is on the left

http://www.smxscreen.com/images/trim-comparison.jpg

Now if we were to use the same flock finish like everyone else uses above, the mask panels would appear to be closer in color to the frame.

So far, the AT mask panels we use have the best acoustical and masking properties out of all the panels we tested to date but we are still testing as new ones become available. Our mask panels don't stretch like other mask panels meaning you don't have to re-calibrate your masking positions periodically.

With our frame and mask bars being as black as they are, they do the absolute best job compared to any system out there absorbing over-scanned strayed light from the projected image. This is just as important because you want a crisp black hole border precisely framing your projected image, you don't want to see the bleeding over-scanned image on the frame. The darker the frame the better perceived increased contrast and sharper border. The mask panels do their job of absorbing the black/grey projected bars.

Screen Research has been using lighter colored mask panels for many years and you would think they would of changed them by now if it was an issue. Keep in mind, they use a flock as well so the frame is much less light absorbing than ours, (see Screen Research mask system below)

Hopefully this post answered your question and doesn't take this thread off topic.

Any news on these new projectors?

The other issue with woven screen material is the loss in sharpness. A pixel grid cannot be made out on them and focus has to be performed with a sheet of paper in front of the screen. Apparently this varies somewhat with the degree of rotation but there is still a loss of resolution with woven material you don't get with a smooth screen. I'm debating going with a microperf for this reason or just accepting worse audio and placing speakers below the screen area as I am width challenged.

heh. A local radio station in my hometown (Memphis, TN) once had a debate about length vs width on the morning show and a woman called in to say "My boyfriend's hung like a can of corn and I love it." They played that sound clip over and over again for years...

I have the same issue. I am very limited in terms of width. I'm not keen on having the speakers below and to the side of the screen either, but it is a question of what is the best compromise, if AT is even a compromise at all?

It is looking very difficult to avoid having to go AT, but for a dedicated HT, is this really such a bad thing? How much are you compromising the audio and the video with an AT screen, given how many of the great rooms run this set-up?

This is my first projector set-up and I am finding it hard to separate the dogma I have encountered about AT being bad for all aspects of a system, from the reality :confused:.

My case is a little odd so take it with a grain of salt.

Being width challenged and still wanting a good two channel system in the same room, I opted for an AT screen that would swivel up and hug the ceiling when I wanted to listen to music. This works fine (with a bit of elbow grease), but the woven material detracts from the picture quality.

You can still have an AT screen with excellent HT audio. I believe a woven screen has better audio characteristics than a microperft but the microperf definitely has better video qualities. You should be able to eq the sound to compensate for either, so it really should come down to the video quality of the two AT materials. Perfed vinyl is better than woven material in my opinion.

There have been debates about whether the audio is sacrificed too much in going with an AT screen, but I think most will be fine with it and it is nice to hear the sound coming from the screen.

i had terrible moire with dlp+ISCO because of an older mp screen with vertically aligned holes
now switched to an ORAY with holes in less number slightly and oriented diagonaly: NO MOIRE whatsoever!! the screen is invisible :)

pvc mp remains king of ac screens vs all woven fabric imho.
maintains ansi contrast, better brigthness, sharpness, "density".

Exactly so in my experience.

LJ, Anyone who is debating that audio is compromised is simply wrong. The audio profile of the screens are very well known and easily taken into account. All the best rooms use correction anyway.

I put 3 Genelec 324As behind an AT screen. The results were devastatingly good. Off axis performance was not an issue.

For those asking about the effect on the sound, if properly installed, your looking at around 2db at the higher end. RT60 remains minuscule.

Make sure nothing, at any masking position, blocks tweeter LOS to seating position and all should be well.

If anyone is trying to decide, get the JVC IMO. I've had nothing but problems with my Sim2 experiences. My Sony Pearl before this, while not as sharp a 1080p picture, was much more reliable and didn't have any of these problems with the same exact equipment... :(

That implies that I haven't been patient; I don't appreciate that. It has been around a year now, and I have only had a properly and/or fully functional projector for perhaps three weeks out of that year, not to mention the large portion of the year I spent without a projector at all. Any worthwhile premium I paid for this unit went out the window months ago. There is a point where patience stops and you just become a doormat.

I can understand having a problem with one, perhaps two, but this is simply ridiculous... I've consulted with a few people outside AVS Forum, and there seems to be a confluence of agreement that this situation is unacceptable.

When I had the HT5000, I used a programmable HDMI matrix.

This allows each input to pass to any output, or number of outputs. One output is connected to the audio, and each input is programmed to duplicate to that output. This works very elegantly and retains the ability for per input calibration. Anyone who wants a more in depth explanation on how this is done, just shout.

Units that didn't need HDMI audio were routed direct and had audio passed via digital. Also, dont forget that SIM2 PJs have an optical out which can greatly simplify wiring, the HOST units retain this facility on the electronics unit.

Hope this helps.

1. An HDMI out from the host would have been the obvious solution. Im pissed that they didn't implement that.

2. Most SIM2 PJs have an optical out.


Also, the simple fact remains that if you dont need calibration of each individual i/p it doesn't matter anyway.

This is how I operated with my HT5000.

Its really simple. An HDMI matrix has a number of inputs and a number of outputs. It allows you to connect any input to any combination of outputs. A 4x4, for example matrix has 4 of each.

One output, lets say o/p 4, is connected to the processor or receiver. o/p 1-3 are connected to the PJ. Connect a BDP to i/p 1 and have the signal sent to o/p 1&4.Thats one each to the PJ and receiver. Lets say you connect an HD-DVD to i/p 2, you send its signal to o/p 2 and 4 and repeat as necessary. Very straightforward.

You may notice that you will have one less o/p to the PJ than i/p as one is tied to the receiver. If you do need that last i/p try to ensure its one that you wont need a separate i/p calibration for on the PJ, that way you can send it to the same o/p as another source as you cant watch 2 on the same PJ. I used a 6x6 so this wasn't an issue. for me.

Remember....If a source is not HD audio capable it can be connected direct to the PJ and an digital cable used to feed audio to the processor.

I've probably made it sound more difficult than it actually is. Once set up and integrated into your control system its totally transparent.

Why only 2 sources of HD audio, it should be 4, or am I missing something?

It should allow 3 connections to the HOST and 1 to the audio, but still utilize all 4 i/ps.

As for an optical out on the PJ.....You can connect a number of sources to the PJ, and only use 1 optical i/p on a processor. Probably not a big deal these days

I was considering selling my Radiance when moving to the C3X, but I might as well keep it, especially since I just paid for the XE upgrade. It seems like a waste to go with the HOST unit when I would use only one HDMI input, also considering the inconvenience of having to run the fiber optic cables. However, I understand part of the performance improvement may be due to getting the processing hardware out of the C3X case.

It is a strange decision of Sim not to have "an HDMI audio out" I used to have an optoma scaler that had this feature.

I am going to Sim UK HQ on Monday and I will see what reason is given for this unfortunate circumstance. However, although I am obviously very important, I don't expect my concerns will persuade them to redesign the HOST box ;)

It shipped last week.

I bought an RS20 2 weeks ago, not for personal use, and was able to test back to back with the original C3X1080. There are others here who have done the same. The C3X1080 is very clearly better than the new JVCs, as should be expected, so I expect the Lumis to widen the gap. The only advantage the JVC had was on/off CR. In all other areas it was inferior.....ANSI, Color, CMS, Sharpness, brightness,Image noise, Depth, VP flexibility, uniformity, motion artifacts and blur, hazing etc. Its also inferior to the better single chip units too, suffering the same disadvantages.

I honestly don't think its a fair comparison. They're tools for very different jobs, and different customers.

The RS20 is great for the price, but certainly not worthy of the deification we see in certain quarters.

Have you finalized the associated equipment or still auditioning for that as well?

Good luck.

H,

I had to drop to 18ft to avoid lowering the floor. The basement level isn't something I didn't want to trash, so 18ft it is.

Almost all equipment is finalized.

The projector is 3000 lumens.... I am headed to Sim at the Hilton Las Vegas in few minutes....Hope to see it in action.
I love the Host concept, it will make the projector dead quiet and no glass needed on port hole.

The screen will be a standard 1.3gain AT screen ( thus around 1.15 gain)

The Lumis wont come close to an 18ft screen at high lumens. The 3000Lumen is actually ANSI lumen. Im expecting around 1400/1500 lumen at a guess.

For the big screen I need way more light. Im looking at the Christie 10k-m and a DPI Lightning reference. I want the ability to hit 30fL this time.

Cant say till we see real numbers. I think 14ft may be pushing it, depending on your fL requirements

One of the main complaints with the 1080 was that it didn't have the brightness of the old C3X720, the Lumis is trying to address that.

I think its $37k for T1/T2 lens and $38k for T3. If thats not exact, its close.

High-Definition Optical Signal Transfer (H.O.S.T.). Its not a VP. It basically rips out the electronocs from the PJ and puts it in a remote box connected by fiber.

The inputs are then massively expanded to equal the HT5000.....6 HDMI, HDSDI, 4 component etc.

Here is a video on it.

I saw the lumis..... It is awesome.
It is not enough for my 12 foot 2:35 Perf screen specially because of the 25 foot throw.
The new HT 5000 E with Darkchip 4 an 10 bit processing was better looking than the lumis. And my humble opinion way better than the HT 5000.
The picture had no digital look and looked like a sharp SXRD with deep blacks.
It retails for 70K and is better looking than Digital Projection Titan which I really liked.

Ash:

There is no difference between the HT5000 and HT5000E other than HDMI 1.3, the Dark Chip3plus and Dark chip4 are exactly the same.

What you probably witnessed and what impressed you was the Source material. Also there may have been DCI color filtering to the Demo HT5000E

Ash Sharma
01-09-09, 06:55 PM

How about 10 bit processing in 5000E versus 8 in 5000?
I saw the Elton John Blu Ray on the Lumis and asked them to show Same content on 5000 E and found 5000 E to be very different from 5000 which I haveauditioned many timesbut never liked it (both projectors were in different rooms).
Funny that 1 year ago I auditioned the 5000 at a dealer in Houston and talked to the Sim salesperson who was visiting Houston from Sim HQ.... the same person was in the demo today along with thier technicians and they confirmed that 5000E is very different from the 5000.
Also, the CR announced is 6000. . . . I am sure we will know more once sumo one has taken real world measurements.

What is the issue with the 25 foot throw resulting in this projector not being bright enough for your 12 foot mp screen,

I use a C3x720 rated at 2500 lm and I have a 25 foot throw.

I would have thought that the lumis would be brighter than my already bright C3x.

Wouldn't a dual-lamp Sim2 provide the brightness you need?

Wouldn't a dual-lamp Sim2 provide the brightness you need?

Unfortunately Not.

The dual lamp HT5000 only provides around 30% more light than the single lamp. This is due to the lamp arrangement allowing perfect uniformity in single mode. There is a way to get double the light from dual lamp PJs but that trashes single lamp performance.

coldmachine
01-10-09, 02:09 AM
Also, the CR announced is 6000

You will get that, as well as the 10 bit processing and the DC4 performance, from a normal HT5000.

As LJG stated, it may be the source that's impressing you, and the fact that there may be new filters fitted to hit DCI color with the special source used.

It that is the reason, and it had that effect on your viewing, it bodes well.

I believe Jason from AVS will be reporting in detail on this. He already confirmed the demo unit was set up to display DCI color.

There should also be some exclusive color and gamma tables for this system.

Ash,

What is your screen gain?

12ft @ 2.35 with a 1.15 gain (1.3 cloth with mperf x2) using a guesstimated 1400 lumen (possibly conservative) will give just over 26fL. 1600 would give 30fL.

The old 720 version of C3X would certainly light up your screen.......addendum........... just saw Warrens post above, which confirms.

Ive currently got 2 C3X1080 lighting up 10.5 ft 2.35 screens with tons of light.

Unless Im missing something, Im also not sure why they would say the Lumis is not for you, other than to sell an HT5000.

I hope so.

The C3X1080 is not as bright as the C3X720 and was one of the main complaints, so just addressing the difference would be good. Beating out the C3X720 would move the Lumis closer to the HT5k in terms of brightness.

I'm getting about 12 ft lamberts on my Qualia now (1000 hrs on bulb). It is not too distracting believe it or not, but I am wanting more punch and more detail in darker scenes (with less punch on my wallet).

If I could get 18 ft lamberts on a broken in bulb, I'd be happy.

What is the formula for figurng out ft lamberts given a PJs lumens?...

Like Ash, I have a slightly larger screen @ 14' wide Microperf X2 (2.35), ISCO (10.5' wide for 16:9)

I can also confirm that my C3X1080 produces a lot of light. I'm at 900+ hours and getting 22 ftl on a 100" (just over 8' wide) 16x9 screen. That's at D65 with the lamp at 220 from a 19 foot throw. When I go scope, my image is 11' wide; the ISCO then moves into the path and light output diminishes by 30% or so, but it's more than adequate.

Ash Sharma
01-10-09, 09:34 AM
The screen is Stewart Firehawk Microperf x2 Cinecurve I am not sure of the gain, I will check.
They were showing DCI from the Entertaiment Server which really looked bad and even thier sales person admitted. The 5000 t is not a DCI machine.
It would be the classical marketing situation when a product positioned as lower end (lumis) can eat into sales of the higher end piece (HT 5000 E).
I am getting tired of living with the anemic (light output) Qualia and low CR and have looked everywhere and at a very broad price range for a suitable projector last few years.
It was interesting that the salesperson wanted to show off new convergence software on the 5000 and used the remote in the menu system only to find that only Lumis has this super duper software.
I did question the fact that the Host does not have HDMI out ( got Deer in a headlight look) which would be great for HDMI audio switching but they reccomended that I buy a switcher...
They were talking of the different light paths in the two projectors but I am not technical enough to understand.
Subject to final lumen numbers, with a 70,000 msrp 5000 being overshadowed by a 38000 Dollar lumis, I am leaning towards not spending a huge sum when something better will come out just a few months later.
I might just visit the Sim suite one more time today a I leave for from at 2:00 PM.
I asked Sony about Qualia, they did not knowwhat I was talkingabout.
CES is not a place for serious video and audio, it is a gadget show. I spent too much money shopping (great stores here some of which not even the galleria in Houston has) and met some friends who live in Vegas.... it was a good time.
I hope this is the one.

Ash, OT but next time you may want to check out THE Show at the Alexis Park hotel. Very serious audio there and it seems to be where the high end manufcturers have moved as the venue is better suited for room setup and is less money for some of smaller hiend vendors to show. It's where some of the most interesting Hiend is happening during CES. When I go, I usually spend 80% of my time there vs. CES.

BTW, what is the convergence software - is it 1 pixel only or is it fraction of pixel capability like the Sony's?
