"World Premiere 4K 3D DLP passive Stack" - Page 2

thank you alan for your nice words but i have to correct you.

the 4k computer i have are not scale up 2k to 4k it feed 2x 4096x2160
NATIVE to both pr.

the pr. itself can scale up 2k to 4k and it makes this perfect.

also if you order this not so cheap 4k imb inputboard with the server
this can do the 2k to 4k scaling and much more......

peter i still dont know 100% what you want to do with 2 pr.?
side by side setup?
both pr. at one picture?
2D 3D ?.......

so please describe it to me that i understand it 100% right.
otherwise i cant get you the right answer.

ok understand now.

that will not works as both optics are different and than
you have to put both pr. side by side or up down and shift the picture and
the accuracy both pr. have in ILS system is not good to do such things.

so its the ils "AND" on top the differnet optics that makes it impossible.

no way you can do it for 2d!

in 3d that is possible as there a small tolerance from 1 to 3 cm at some area is not that big problem if you have a lets say 5 meter wide picture but not possible in 2d as there it have to be almost pixel perfect.

i cant match my 2 pr. as well for 3d passive perfect.

the best i can do with my set up is almost perfect over the whole screen but
at the left down corner i have some areas that are 3 cm out.

may it will help to movie both pr. more close together but than it will be
difficult to change the lamp or do other service.

also helpfull to make it better but thats for me not possible in my setup is to
use more long throw lenses.

but again even with very long thow lenses both pr. without any space
for 2d you should forgth it.

i will go down after some days not work with the setup and take a look about
the 3d that looks a bit strange.

better use sunglasses than have to use a night-vision equipment

thats complex to anser it short here as there are so many things invole
like how we human can see how our brain works for seeing and
many other things.......

i will try to keep it short but i will not go inside in more details as i cant
shrink scientific books to some letters and i not have the time to
write this books again her.

beside the sony 4k pr. that act like a double pr. set up all
lets say 95% or more cinemas that show 3d with one dlp have some
motion bugs visible that a passive stack not have as only they can display
both (left and right picture) at the same time at the screen.

all other systems in 3d that show left righ alternate will produce some kind of
motion bug as the shutter cant show both left and right at the same time
and therefore when frame 1 was gone and frame 2 was displayed our human
eye see even if the picture was black for some milliseconds a picture.

its like in the old home cinema days the delay time from the crt pr. tubes.

as than the frame 1 ends with left and the new frame 2 starts with right
you can see for a short period of time a mix between frame 1 and 2 and
this is the motion bug in 3d 95% from all cinema and home cinema pr. and
tv have.

i hope this is understandable.

i dont know what you means by FI?

so far i saw all 2d blue ray material with the barco dvi inputs so the barco upscale it from 1920x1080 to 3840x2160.
no bugs at all visible and a perfect picture ..you will see soon.

3d blue ray i need the doremi imb in a single stack 4k pr.configuration with shutter.

it will be interesting to test some day if there is a difference between the
2k to 4k scalling the barco did and the doremi imb
but i doubt there will be a difference.

by the way if you cant see the bright light may my wife try to cook but found out that we lost power.

i told her to not cook when i use both pr. at each full lamp power

here a picture that explanins what i write about the motion bug
every single 3d dlp pr. solution have (beside the sony 4k) in post number 48.

thanks Mr. Peschke for let me post it.



when frame 1 was gone and frame 2 was displayed our human "brain"
eye see for some milliseconds both pictures left from frame 1 and right from
frame 2 (or opposite) as our eye/brain have a small delay.

thats why most people prefer a passive 3d solution.

i saw the sony 4k pr. that act like a double stack as it have both left right
at the same time on the screen and it looks very good.
the best avatar in a cinema and on pair with a double stack
dlp system that also looks very nice and bright.

ok i will tell her your proposal but i cant guarantees you anything

today new much stronger exhaust fan
are installed and also a new air in system that feed the new pr.room
with till to 3000 cubic metre per hour very fine filtered air.




also the new air tubes are installed.

it takes all together almost 10 hours as we have to drill new holes
into the very strong concrete that my basement have.

later the electric installation will be change as i wish when i start one or twos pr.that the air system will start as well and even runs min. 20 min. longer when i switch the pr. or the lamp of.

Nice to hear this from a cinema owner thank you.

But I can say that I am also jealous as I not have access to DCI Content on a regular base .

Knowing how big the difference is between a good bd and good DCI content can be very
frustrating for me when I did a A to B comparison

About your question.
Yes it should be possible.
One 4k pr. I have have just the input board with 2 dual link dvi input the other one have the doremi 4k imb inside
plus this dvi inputboard.

When I feed a 2d blue ray at 1920x1080 at 24p to the 4k that have just the 2 dvi inputs (with this new software
I have) it scale up it to 3840x2160 so this must be the TI scaling as there is not any doremi inside.
I don't know if this is TI scaling or Barco.

The other 4k that have the 4k imb on act similar so I thing just by using the dvi inputs you are safe that the TI/Barco scaling was used.

I think a NEC 4K act similar.

The problem I have is that I cant use the hd dsi inputs the doremi 4k imb have but I think that problem doremi will solve soon.
I think its just a new macro that is need.
