"World Premiere 4K 3D DLP passive Stack" - Page 7

post #181 of 229
I am about to get a Barco 4K projector hopefully, but the estimate I got says the dp4k-32 requires 3phase Power. Do you have 3phase electrical? No normal home in the US has 3phase power. is that correct info?

I'm pretty sure I will be going with the dp4k-23. The DP4k-32 was a little out of my price range. The DP4K-23 uses standard 240v power.

Do you know what the contrast is on your 4K? I was told there is an issue with the 4k units not reaching their 2000:1 spec contrast. Since you don't mod your units for higher contrast because of wanting so much brightness, does your black levels bother you at all? Or is it only really noticeable on a completely black image?

I'm really excited to become a DCI owner, but just want to make sure I have done all my homework.

Also for 2D I can just directly feed my bluray or satellite etc into the projector via one of the dvi inputs and it will automatically scale it to 4k?

Seems like things only get more complicated for 3D sources!

Thanks for the help!

hi chris

yes the b32 need 3 phase.
i am not sure what the b23 needs but i think it 2 phase but a lot of power so they need a big connector.

yes the cr. is in the lower than 2000:1 range but i am almost sure that the new upcoming lenses will have a better cr.
they should be out in around march so not to far in the future.
i will upgrade both units with it as they will offer for sure bigger shift range
better mtf at the center and corners and as i hope a better cr. as well.

no one that saw this unit in action even with dim material complain about cr.
but yes if you compare it to a 2k dlp its have a bit less cr.

for sample uwe that saw my setup go and order one unit for him.
see his tread in this section.
i called him some days ago and seems he is very happy with the unit.

the easy and cheap version is to watch bds in 3d to wait for a new unit that splitt the 3d output from a 3d bd player signal into 2 stremas left and right(sorry i cant say more about this unit at this time).
this unit will be soon out and than you just need a double hd sdi input and 2 boxes for hdcp and two cheap hdmi to sdi converter.
than you just feed 2 seperate stremas left and right thats it.
But please note if you order this double hd sdi inputboard you need the encryption board as well as the hdmi inputboard need even if you feed not encrypt material!

the other expensive but very easy way get the imb and you just need to plug the hdmi cable from your 3d bd player and watch 3d.
or you need the setup how i run 3d bds at the moment see my older posts.

in post number 171 i discribe what the pr. can take as a input signal over dvi.

Chris,

Three phase power is not a problem. There are several converters available that have standard two phase input and three phase output. I used one for my Barco DP-100 and the cost was in the $5000 range. There are much lower cost converters, but they seem to be specifically designed for electric motors and may not work.

It seems that you will need only two phase, but PM me if you need information about the converter that I used.

If you are in florida email Peter he can help you.
post #185 of 229
Wouldn't it just be cheaper to get a three phase hook-up? Overhere you have the option as you most likely need it if you use an induction cooker instead of gas. Getting those high capacity single phase lines you folks often speak of here is not that common.

I confirmed with Rick Gordon of RPG whether the material for the HFR demos at Moody was played back at 4K. Here is his reply:

"This was all true 4K projection. The 3D material was at 800 Mb/sec total, and the 2D material was at 400 Mb/sec. The material was shot on Red Epic cameras at 5K, and downscaled to 4K in the D.I. suite."

i am sure that today no 4k dlp pr. can take more than
24p or 25p in 4096x2160 and display it.

possible at 30p is 3840x2160 but i am not sure.


so 4k in 3d may are possible at 24p yes but not together 4k native in 48p or 60p.

this link also say "high bit rate 4k 3d" but not say high frame rate in 4k 3d!

they mix it up in the report with high frame rates but not high frame rates in
4k native 3d.

4k at 48p will be possible via a hardware upgrade by 2-3 quater 2012 or later.

it will req. a new inputboard and other changes.

60p in 4k it still today a question mark but i hope for it.

the server is a other story.

but all this is very very early for sample i and a big germany cinema wait
for a solution to drive two 4k dlps with 3d """2k"""cinema content
in a passive stack and till today no option for this you can buy
post #191 of 229
Wolfgang.. i had read your thread over and over trying to wrap my head around this setup.

I have just a couple of questions:

I know you a one time you used the Reald CE4 glasses. How does the RealD emitter with BNC connect to the DLP 4k. I know you use to use those with your 2K Barco but hope they can work with the 4K.

For 3D Bluray to work with a singe projector with active glasses, the HDMI Frame Packed would need to be converted to dual HD-SDI? correct?

Thanks,
Chris

yes the ce4 glasses will work with the 4k dlp.

yes at this time you need this to drive the 4k pr. when you not like to spend the money for a doremi 4k imb.

but there is a other company i can not say today the name will comes with a
box where you input just one hdmi cable from a 3d bd player and it will output 2 seperate hdmi in 3d left and right.
i am not sure as there is in the menue from the 4k a part that say 3d input at dvi so may guess is this input can take the 2 outputs from the box and display it in 3d.

Sorry I could not reply before. I must admit I do not have the answer to both your question. I unfortunately could not attend the Galveston show.

You might consider auditioning the latest SONY SRX Cinema Projectors! We have been working hard to increase contrast ratio and MTF accuracy for the past 10 years, and I'm sure you would find a properly calibrated unit to offer superior image quality to the current Barco and Christie Digital 4K models. And some models are available with Single-Phase 240 Volt Power input.

Furthermore, there will be a NEW family of SRX Projectors coming out this year that are based on the smaller SXRD 4K chip set found in the new SONY ES1000 Consumer 4K Projector :-D

Perhaps you and I could conduct a carefully thoughtout comparison between the current BARCO and SONY 4K Projectors, here at Kipnis Studios?

I'm certain the event would get world wide exposure :-D

I dare you! Have Peter get one of his Barco "tweaked" 4K and bring it on
post #199 of 229
So we need to conclude from this that the JVC/Kenwood 8K is not as good as the Sony 4Ks.

post #201 of 229
Perhaps we could arrange an industry event where all the 4K (and perhaps 8K) projectors are all on display under identical conditions. True 4K (and 8K) source material would come from a wide variety of sources (including 3D at 24P, 30P, 60P {and even 72P}) with demo sections lasting a minimum of 5 minutes each.

Who is interested (and how can YOU help facilitate this event)?

How can I find out how many lumens each lamp will give.

The DP4k-23B says 24,500 lumps with 4kw lamp

How many lumens will be available with 3kw lamp and 2kw lamp. I can't find this info anywhere.

Thanks for the help!
post #203 of 229
Wolfgang,

Im sure you can answer this. What is needed to get 4K resolution out of a computer into a single Barco 4K.

I know you are doing this with 2 Barco projectors.

What is the simplest connection? Can this be down with DVI?

Thanks,
Chris
post #204 of 229
Hi chris,

IMO You are looking at this the wrong way, think apertures instead of lower watage lamps.

But if you look at the spec of the 19b you will get an idea of the lower lamp.

One thing you don't want is a 2k lamp unless you have an 8 foot screen.

the 4k duak dvi is at 24 frames per second.

the 4k duak dvi is at 24 frames per second.

So I should use a 3kw or 4kw in your opinion? The screen is 14' wide scope SMX 4k material, like you have used.

the 4k duak dvi is at 24 frames per second.

since long time some people report the 4k imb can feed with 4k material but this is not right.

the sony first 4k home cinema pr. the vw 1000 are the worldwide first display at all that you can feed with 4096x 2160 or 3840x2160
with only one hdmi cable.

the only way to feed 4k to the big b32 or b23 is via 2 dvi dual link that the way i did it see my early post here.
you can feed 4096x2160 at 24p or 30p.
the software to do this is now out.

or you have the 4k imb inside and have cinema content in 4k


i thing the 3kw lamp will give you almost 20.000 lumen.

lower xenon lamps have a bit more efficiency means more lumen per watt
than bigger ones.

Mayer or Peter. Can you tell me what graphics card I will need to do 4k output with 2 dual DVD cables?

I got my cheap 4k video card in today so I can do 4k over hdmi into the Sony 1000 and wow what a difference. That is truly the only way to grasp what a 4k machine can do!!
post #208 of 229
Chris I just installed the AMD 7970 to drive the JVC 4k which takes 4k on two or four DVI inputs. Like mayer I believe I have to convert each output to duel link so I will need a DisplayPort http://www.accellcables.com/products...DP/dp_dvid.htm on each output.
Anything through the HDSDI ports the projector will provide the scaling.
post #209 of 229
Chris I hear 7970 is the only amd that does 4k over hdmi. For the Barco though I believe it is an Nvidia quadro with twin dual dvi. But it is only 24fps.

most of the reader of my posts know i not like anamorphic lenses or other
filter or lenses in front of a high end projector.

i try in the past a lot of high end anamorphic lens and the best i try was the big isco3 with 1.33.

as i now use the sony vw 1000 at my big screen to show all what is not 3d i
need all the light the sony can output.

even the over 2000 center lumen i measure its hard for me as i can only have
around good 7 ftl at my screen.
so i try (as the native resolution from the first 4k home cinema pr. is 4096x2160) a dlp anamorphic lens from isco with
facor 1.25.

i was very surprised already with the sony as this lens have better picture quality in the corners compare to the best 1.33 isco i ever try.
also chromatic bugs are less and distortion was also less.

so as the result was good i try yesterday this lens at the big barco b32 4k dlp and it was a even bigger surprise to see that this anamorphic lens works perfect with the
b32 lens together.

even at 4k resolution there was almost not any picture quality decrease visible.
almost
-no destorsion
-no chromatic bug
-no sharpness decrease in the corners.

see here some pictures where you only can rate the distortion.











i have no idea why it works so good in this combination but i guess as the
anamorphic lens was a DLP Cinema lens and the lens inside the barco
b 32 as well they are may tuned together.


as I do my 4k 3d pictures myself I can process it in a anamorphic way so I will now put on my second barco b32 this anamorphic lens on to have true native full 4096x2160 pixels in 2.35 format with a good 20% light increase
or if you turn the anamorphic lens 90° a 1.42 format screen with all 8.8 mp and all the light.
this is almost IMAX FORMAT in 4k 3d
