3D Theatre - VIP Product Thread - Page 6

are there any reviews yet with low lumens 1080p projectors?

I live in the uk and asked VIP the same question about my Sony projector and they have confirmed it does work.

My projector is 1000 L so if u could find out that would be great!

It will probably work but will it be bright enough for you? Too many other factors at play. Size of screen, screen gain, age of bulb and how many of those lumens are already lost. Longer throw distance lowers lumens too.

You could probably raise brightness to make it watchable. Contrast can't go up any higher so basically your contrast ratio would be much smaller. Can you live with peak lumens only yielding below 10ft-L on the screen?

These are all your decisions. Nobody else can make that decision for you. Some people can watch with peak ft-L at 4 or 5 and not be bothered by it.

Does anybody know where Jonathan Alexande did go?

I send him a qouple off emails but he doesnt respond anymore.

Before the payment he was very quik with answering.

The last thing he mentioned that he recieved my payment.

But i send him some questions so as if there other glasses that are comptible if i need more(i ordered two pair with my vip theater)

can i use the xpand X101sc?

And when they gonne send my package.

Best regards cees beekhuyzen from holland

What we need is to know what precentage of light is lost with the glasses. Then you just subtract that from the ft-L you have on your screen now. My guess is we would lose about 60%. In my setup with an old bulb I get about 12 ft-L on my screen so I would have about 4-5 ft-L. With a new bulb I'll probably have about 8 ft-L on my system. Keep in mind I have read that IMAX theaters can be down in the 4 ft-L range when watching 3D movies. Your local theaters are probably about the same. You'll want to have a very dark room with dark walls to get the best image or you could just shrink the image size to get a brighter image.

haha, quite possibly

just a thought, and this may have already been answered, but has anybody compared the results of running the theater in 120hz 3d mode vs 60hz normal mode on the same DLP projector such as the Acer h5360?
So using DLP Link glasses in 120hz vs emitter glasses in 60hz. I'm thinking more in terms of the difference in brightness between the two modes as obviously there's a drop in brightness when choosing DLP Link 3D mode on these types of projectors whereas the normal 2D modes are super bright light cannons!

Heard from Jonathan today. VIP Theatre boxes will start shipping April 7th in order they were preordered.

Cool. I'm looking forward to trying this out.

With shutter glasses, the loss is 84%. I wish it were only 60%!

And I'm looking forward to your review using the VS Pro8100!!

84% !! Can't be that much. Even if you had 40ft-L in 2D you would only have 6ft-L with 3D. I am figuring you lose 2/3rds of your output.

84% would mean you only retain 16% of your light output. That's nuts! Every front projector would be way too dim. Even flat panel TV's would struggle.

Remember, the best you can get is 50% light transmisson (meaning a 50% light loss) due to the Duty Cycle (Left eye open, right eye closed)

Oh gosh, another small delay. Jonathan originally said they would ship today. Wonder what happened now? At this point, might as well of waited on the shipment of 3d-xls lol. Does anybody know if Consignia will be getting the first shipments?

To be fair, Jonathan said they would ship "The first week of April"

Well I directly asked him on the phone and he said the 4th. This is what Jay at cosignia told me he said as well.

Who knows, they might be filling the retail pipeline first--so that they both can ship at the same time. Let's face it, he can't afford not to get this right. He's got one shot at it or he loses a big customer base here.

Oh, I wasnt being serious or anything. Its just a couple of days. We've already waited this long whats a couple more days. I'm just hoping that cosignia is shipping this week.

And like the above guy said he is meeting the first week of april deadline. I just asked him for a more specific guess and that was his response. But getting shipments in late and other variables can change everything. Does anybody know if the displayers are shipping at the same time as the others? I know he said they all arrive as displayers and that he installs a chip and firmware in house that turns them into the theaters. So this was going to take a 3 days or so he said.

I wouldn't go by the meter reading with the shutters going. It wouldn't read quick enough. The open shutter reading is more like what the glasses do at reducing light levels. So 12% to 13% plus the 50% loss in duty cycle. So 62% to 63% light loss.

If it were 84% loss all displays would be unwatchable. 2ft-L off the screen? NUTS! Way too dark. 4ft-L is dark enough and more in line with the readings found in IMAX theaters. They were designed for 12-18 ft-L on 2D movies and with the shutter glasses that puts them in the 4 or 5ft-L to 7 or 8ft-L range max.

I have been to a guys house that had an old CRT setup and he was living with 4ft-L on 2D video and was quite happy. It took a half hour to get used to it. I can be very happy with 8ft-L.

Best thing to do is watch regular TV with sun glasses on or put an ND filter in front of the projector to knock out 60% to 70 % of the light for a while before starting a 3D movie. Actually thats a good idea. I have some ND filters I will look at my projector while removing 75% and see if I can handle it.

The slower the meter the better. You want to read average, not instantaneous brightness. DCI 3D brightness spec is 4.5fL but that's usually off of a silver screen with about 2.3 gain, equivalent to 2.0fL off a 1 gain screen.

It does say reading through the glasses is not an accurate measurement and that you should measure a 2D source and calculate. Although it does say shutter glasses are only 16% efficient. I don't see how any one can use a front projector like the JVC's. You need at least twice the light output maybe more and a sub 100 inch screen. Better off with the biggest plasma or LCD flat panel you can find.

Thing is I have looked at the Panasonic 3D TV's in Best Buy and I didn't think it was any where near a 75%+ light loss with the glasses on. It appeard to be close to 50% plus a tinny bit more. Not 84%.

Going to be a lot of upset people when they get these devices if you ask me. If people think its bright enough then these figures are wrong.

Going to be interesting reading this thread in the next couple weeks.

IMHO

Chezbrgr2--Absolutely excellent! Thank you for that!

Awesome video, Chez! I can't wait until my unit ships...!

Thank you Cheez, its nice to see somebody go out of there way and post a video of their unit finally. Congrats! This product has a huge market and advantage over the 3d-xl and vp3d1 imo.

Thanks for taking the time Cheese, really appreciate it!
