after i am "almost sure" that i can find a way to feed my 3d pictures

2048x1080 with one computer via one dvi out

to the barco dp 2000 and this pr. can display it at full resulution

in 144 hz flicker free (2x72 hz per eye)

i order this unit.


i had in the past 2 christie hd6k 3 chip dlp pr. 1920x1080 with 1000 watt xenon

and i like this pr. a lot.

no pr. that i have during the last good 1 year at my home can match the

picture quality this christie pr. had.


i use 2 because i do 3d with a 3m wide silver screen with passive polarizer.


it works fine but it need always much time and adjustments to switch between

2d for films at the big 7m 2.35 screen and 3d at the small 3m silver screen.


my goal was to do 2d films AND 3d pictures at the same big 7m screen (harkness hall matt preview gain 1.0)

with only one pr.in shutter for 3d.


i saw some 2x 60 hz 3d but i can see some flicker so the only way was to

buy a cinema unit that can runn in 144 hz flicker free.


there was only two projektors at the moment that can do that

at the full resolution 2048x1080 in 144 hz.


the barco dp 1500 and the barco dp 2000.


both units are identical more or less.

the 1500 can take lamps till to 3000 watt the dp 2000 till 4000 watt.

both using the new 0,98" cinema chips 2048x1080 with dc4.


there is a lot of work for the pre instalation as you can see in the first pictures.


new much stronger power supply is need havy intake air strong filtered to protect the unit from dust

and exhaust air all that the christie pr. all not need.


how it perform against the christie hd 6k

is cinema prozessing really better?

did i can do 3d as i hope?

what problem the pr. have?


that all later.

1 Can the DP3000 also display at 144Hz?

2 Is the DP3000 also using dmds that use the DC4 process or are they older and still only DC3?


Do you have any interest in moving 3D pictures or are you primarily interested in 3D still photography? I sometimes ask myself what I would prefer a 2D moving pictures presentation with good depth or a 3D moving pictures presentation.

1 yes it can but as i post already not a full resolution 2048x1080

max. was

1628 x 880 flat

1920 x 804 cs


2 the use the old dc3 chips 1,2" and electronics.

how it perform against the christie hd 6k?


i use the christie hd6k with a isco3 optic in front and that kill the ansi

cr. as i have post since long time.


but for the test christie hd 6k vs barco cinema dp 2000 it was no problem

because i runn the hd6k without the isco3 lens.


here are some numbers that both pr. have


christie hd6k


6800 centerlumen at 150 hours no iris

at normaly color 6300 centerlumen at d 65

cr. on off 2650:1 iris closed at 9 for normaly

color about 2440:1 at d 65

open the iris will decrease cr. to

2300:1 at normaly color and

2150:1 at d 65

ansi cr. 650:1 at normaly color




barco dp 2000


17200 centerlumen for 1920x1080

18370 centerlumen for 2048x1080

lamp on 50 hours(lost about 8% so the unit have new almost

20000 centerlumens
)

numbers after color calibration

at cinema color

d 65 cost -11% light

2312:1 cinema color

2060:1 d65 color(reduce 11%)

ansi cr. about 750:1 have to measure again







i use a new lumagen radiance scaler and a spatz hdmi splitter to feed

the same signal into the units.

but as the barco have no adjustments at all even not cr. and brighness i need to

make 2 different banks in the lumagen to make it easy to switch between the 2 units.


as i can almost dimm down the barco to the light level the christie offers at max. light out

it was fast clear that

both units make a very good picture and there is not day and night differences

between them.


the most disappointment was to see that when i drive the barco at cinema prozessing that this

NOT reduce the fals contour bug as i hope for and as many people told me.


than the secound shock.

all fine details are filtered out!

so some test pattern show that drop in high freq. very good.

i talk with barco but there are some adjustment deep inside the unit

where you you can switch that filters off.

after i did it it shows the same sharp image with no decrease

in high freq. anymore.


the cr.on off number the barco have is not as good as the christie

can do at iris 9 but i never feel it looks wores.

i think the high ansi cr. make this difference or and the better cinema optics as well.

the barco picture looks a bit more sharp and a littel more 3d like.


i had about 40 ftl on the screen when i did the tests and i never fell

even in dark seq. like casino rojal chapter 5 that i miss some cr.

also it was interesting to see that even with the barco have about 15% more light on the screen

as the christie the cr. visual looks better with the barco!

i dirve the barco in cinema color as i like the bigger color bandwidth

and i use the lumagen do drop the 2.6 gamma that the dp 2000 use when

it works in cinema color.


the color calibration later not change it visible much so the pr. was out of the box

good in color.


in summary i can say that both pr. make a outstanding picture.

if you not count all the problems a cinema unit have see my fist post

and you not count the price i think beside the more lumens this barco have it is

a little bit better mostly thanks to the dc4 chips.


for me as i rate the new barco only as a 2d pr. that show movies its a stepp up for me

as it shows a bit better picture and the lens i use works with the 2.35 format screen without any

isco 3 lens and thats also a improvment.


so all in all its the better pr. for 2d movies but the differences are not that big.

please note that i not use a cr. improvment as the

dp 1500 from peter have because i need all the light for 3d.


i hope some day they find a way to make it adjustable

and than i will also gain cr. by almost double for 2d films and

still can use the full light for 3d.

Will you be able to loan and view a D-cinema source in your home? It is always special to view things in your own setup.

I am glad that you are happy with your upgrade. We are looking forward to your reports on 3D performance.

So if you need the light output for 3D or large screen this is the way to go. Also DCI machines have the color filters allowing for wider color gamut. Im hoping some of this color technology trickles down to consumer level soon.

3d


as i post already the main reason to buy this new pr.is to

do 2d AND 3d at the same screen with only one projector

instead of 2 pr. and no additional small 3m silver screen.


i was only "almost sure" that i works in 3d like i hope.


so the unit arrive me and some days later i got my pc back from

mr. trautner in austria that modifi this pc to output my

3d pictures at 2048x1080.


he also build the sync box that i need to drive the emitter

that controll and sync the shutter glasses.


for some reason it not works.


i try it 2 days with the help form mr. trautner and than he build a new sync box because we think that

this one is brocken.


but some days later i got a secound one but

even with this new box it not work at all.


i was very frustrated as this was the main reason to buy this pr.





i contact barco than and after some days barco told me that some early units

have a bug at the 37 pin connector.

the connect it inside mirrored so the pin are not right connectet.


i change this and from that time on it works in 3d perfect.


than some days later a other bad news.


i must discover that my calculation about lumens in 3d per eye are wrong.


i not count that if you do 3d aktiv with one pr. than you measure on the screen

(the left and right one the same time on the screen see this picture)

both pictures left and right at the same time and that doubles the light output.

when the shutter is in between the picture you see ONLY ether left OR right so

to make it easy to understand

"i have half light on the screen as i original count".


my mistake but as i already ordert the unit that have the highest lumen out

i cant do anything about it.


so now depends on the screen size i use in 3d 5,3m wide is max. because of my 2.35 format screen

or min. 4,98m(that is the smallest picture my optic can do)

and depens on what shutter i use(i have both the nuvision and the cristaleye)

i can get between 12.6 ftl to 17.5 ftl in 3d to the eye net with a new lamp.

that is compare to cinemas where you have in 3d between 3.5-4.5 ftl a lot but

not as bright as i original thought.


as i work with the unit now sice some days i begin to appreciate

how nice it was to have one pr. for 2d and 3d at only one screen.

reason is also that all adjustments(size lamp output focus location horz. and vert.and all the rest)

can be stored as a macro and just one push brings me from 2d in 7m 2.35 format to

3d at 5.3m at 1.89:1

very very nice.

just done.


yes i will get a cinema server that can playback 2d and 3d content.

i also will get some demo material in 2d and 3d and hope for a solution

to get real content

cr. on off improvment.


its some how sad that i not can order the cr. improvment with the

apature plate as the dp 1500 from peter have because

i need all the light for 3d and this tool it till today not

adjustable its fix inside or not.



my hope was that a apature plate at the openig of the lamp house

will do similar things but to keep it short it not works.


i found only one shape that is not on the picture(cat eye shape) that increase the cr. on ff by arround 18.5% but that costs 43% light.

that is not very efficient as when you have such a plate in the light engine

it costs about the same light drop but it gain cr.about 80%!!!


now i have hope that the company that do the cr. improvment will find

a way to make it adustable from outside.


some day this feature will be for sure inside some pr. may also

prof. high lumen projectors.

problems:


the pr.have some problems when it arrives as most other pr. as well.


convergenz was not good the tuch screen have a bug and the thing about

the 37 pin connector are not nice.


all that are solved by barco very nicely and fast.

i got a new tuch screen that works so far now without any problem.

i get a 37 pin adapter that corrects the bug and the convergenze was

after the adjustments very good.


summary:


this pr. is not a normaly home cinema pr.

it demands a lot of special ambient conditions and its not designt to runn in a normaly home cinema room.

it need at least a seperate pr. room.


but as the home cinema screen gets bigger and bigger and at the same time

more and more people like to have above 25 ftl on there screen or more


there is a market for such pr. in home cinemas.


for most user that are not do 3d the should order the unit WITH the cr. improvment as it almost double the on off cr.


there is no need for the dp2000 because the

dp 1500 can take till 3000 watt xenon lamps and they should give

you 12000 lumen without cr. mod. and about 6500-7000 lumen with it.



if you have or plan a big screen over 4m wide and you like it bright

the dp 1500 with the cr. modification that give you arround 4000-7000 lumen

(depends on the lamp you put inside)

at 4000:1 cr.is the pr. for you and i think that is at the moment the best pr.

for such a set up.

this pr. can be the ultimativ solution.

I thought I read some place where you said it had 40fL with the provided aperture plate.


Yes, you with a familiar scene of some scope scene and in HD.

hi art


yes i made the test barco vs christie at about 40 ftl but

if i like i can now go to over 60 ftl for 2d at the 7m screen.


for the pictures i do "ONLY FOR YOU" i use this 64ftl



as the avs picture quality here is limited i send you a 13 mil pixel picture

with pm.


ALAN IN THIS HIGH END SECTION YOU SHOUD ALLOW 1920X1080

OR BETTER 2048X1080

BECAUSE THAT IS THE CINEMA STANDART



its may interesting to take a look at the last 2 pictures.

both show the same image at 7m but only the camera position was

different.

the last one looks much bigger as the one before or?
