Sim2 Lumis 3 Chip DLP little Test

i got yesterday the sim2 lumis 3 chip dlp pr.

that get a lot of attention after alan and cm get

the units and report about it.


the unit i have is like the others not a series unit

but a unit that have some news inside the 2 other units not

have.

its a good runing enegineiring sample not for sale only for demo.


optic is t2.


a technician from sim2 was with me.



i measure all numbers in the biggest

picture the optic can do.








i found 1900 center lumen at d 65.


cr. is 18000:1 with db on and 5300:1 with db off.


color looks very good right out the box but i am sure a real

perfect calibration will give a better result but may cost 5% light out

as the pr. was very good already.

the pr. have the software inside to calibrate it perfect.

its nice to see how good this uhp lamps can get.


convergence is not to good.

in the center almost perfect left about 0,75 out red and

right is 1 pixel out also red.

also top and down red is out by 0,75 pixels.


beside "pixel to pixel" all other aspect ratio settings show big over scan.


so number wise this unit is behind the 2 units cm and alan have.




it was told from sim2 to me that there are some reasons that are.


-this unit have a new road integrator and therefore the cr. and light out

numbers

are about 25% lower than the 2 other units.

this will change with the delivery of the series units and they will

put new parts inside that match better with the new road integrator.


- the manual iris is not working at all so we simply dont know in what

position

it is at the moment.


- last but important no one know how many hours the lamp have but we guess

between 300-500.

sad that they reset the lamp timer that show 1 hour but this lamp runs

since

long time at sim2 lab.



more important as counting numbers is how the picture looks.





I NOT LIKE SCREEN SHOTS AS I POST MANY TIMES HERE.





as you can see in the pictures we have a jvc rs20 and a lumis at the 7m

screen at the same time.

both display a about 3m wide picture simultaneous.

i measure the on off cr. from the rs 20 with 26000:1 (iris open for max.

light out)

but the lumis is more than double as bright even when you dim the lamp to

min. down

when you have db on.


i watch about 1 hour long Casino Royal and i can say that only some very few

sequences

the rs 20 is on pair with the "visible cr." (with the eye) the lumis show.


in 99% of all material the lumis beat the jvc in cr.(visible) because of

much higher ansi cr. this unit have.

(guess the lumis have close to 1000:1 ansi cr.)


light out wise the jvc is far behind the lumis and sharpness 3d looking all

this show the lumis in a

very very high quality much better than the jvc.


for the first time ever since i sale my g90 stack i saw i picture with a

digital pr. that have no haze on.

very clear even in very dark sequences.


and this even with the lower number compare to the 2 other units



i can keep this pr. till monday morning so i will do some other tests

as well.


i think this pr. is a big step up in picture quality and when sim2 hold

there promise that

the series unit will be have the cr. and lumen the 2 units alan and cm have

this unit is a must have pr. when you can afford it.


it should have enough light to drive a 1.0 gain screen till to 5m wide

if the room is dark.

that gives you when the series units have 2200 lumen around 14 ftl with a

new lamp.


sad for me is that the light out is not what i need to drive my big 7m

screen.


as i like it bright i need around 7000 better 9000 lumen to have my goal at

bigger than 27 ftl.


but lets see.....

here a new picture.


pioneer bd 71 player at 24p direct to the denon a1 to the barco cinema pr.

use d65 rec 709 with a bit recuce color saturation at the bd player.


are the direct picture from gradius2 from a blue ray or cinema content?


in the left uper corner you can see the sky and i never saw at any high end set up the sky looks in this peculiar blue.

may you can tell how you do it.


art you are right about this:

"My thing with screen shots is if used to compare same room, same camera, for some things they are very telling. For exposure light output, gamma, shadow detail, for example , they are not."


i have a nice picture i do only for you but i not will post it here.

but you will get it

Hi W.Mayer,


It's direct from blu-ray, the only difference is it was downsized to 720p (~1280x720), but w/o any black bars on screen.


Real original is 1920x1080, but should be no loss (colors, aspects in general, etc) here, it was just downsized.


Grats on your photo, very close indeed.

hi art


as my 4000 watt xenon lamp have now almost 300 hours for the

first time i can see this picture below 30 ftl (arround 27ftl)


but as this is in min. lamp power i can still go up with max. lamp

power to arround 52 ftl if i like



i try that level several times.

it looks great very nice if the source material is very good and if the movie

show all the time bright seq.


its not nice when the source switch between bright and dark seq. as it arduous to the eye.


i feel very pleasant if i runn it at arround 27 to max. 35 ftl.


more i not like but below 25 ftl its hard for me as well.


the good thing about this level is that your pupil even in dark seq.

not go up and therefore the black level looks still very nice.


thats by the way a good sample why numbers are not always tell

everything.

no instrument have a pupil that go up and down but our eye works this way

I've noticed that myself with my system. I had 10fL with my CRTs and 24fL with my DLP . When it drops to full black out it still looks pretty black due to the effect you mention. Of course ,when that adaptation doesn't occur you can see that the blacks are raised but that as an issue comes up less than I would have expected.

It seems mostly noticable in preview movie trailers

Started the owners thread. Will take some time before I give my observations. I need to allow it to settle in, as I usually am rather dissatisfied with every new projector I get for some reason. I think I tend to set my expectations way too high.

Well, you will have to allow it to "burn in" of course!


Looking forward to your observations...
