Barco Thor 4K 6P Residential Laser Projector the best in the World?

[w.mayer]

Hi Dirk

yes I also hear that JVC will support the 1.25 Isco Anamorphic Lens "the very best in the world" and this is really good news!
I read a lot regarding Sony VW870 vs JVC NX9B and all and both based on early prototypes that often not have full Funktion inside!
For sample the NX9B had not a working adaptive iris inside some other things are not ready with this prototyps so i found it funny to read in other forums hundreds
of most of topic posts that talk about if this or the other pr. is the winner.

From what I have hear is that both Pr. have a nice image.
Numbers are less important but just for fun do some counting based on the numbers we have.
The JVC will have nativ in the 30.000:1 on off cr. with a adaptive iris that normally boost cr. by factor 8 to 10.
So you will see adaptive around 300.000:1 on off cr. at the screen with a adaptive iris.

The Sony will have about 15.000:1 on off cr. with a daptive iris 8 to 10 you will be only at 150.000:1 cr. but on top Sony
have a laser diming that will boost at least 30 possible 40% on top so that the Sony will show at least about
200.000:1 on off on the screen.
As JVC use 4K to 8K wobble this will further reduce the ANSI cr. compare to the Sony so my guess is the Sony will be have a better ANSI Cr.
The question will be is the 200K on off vs 300K on off cr. really visible or will the higher ANSI cr. cover it.

My guess was both pr. will set new reference black levels that some time ago no one think we get soon and that both Pr. will offer a very nice picture.
Some will order the JVC some the Sony but today declare a winner is not very professional.

JVC Lamps are in the last time do not lose much light soon so when you count how many lamps you can buy that cover the more money you have to pay to get a Laser
the JVC can be an extremely good buy.
I don’t know exactly the price but you can buy at least 10 lamps I am sure for this price difference.
Now you change let’s say very soon always the lamp after 500 hours to maintain the high lumen level you can watch 5000 hours long and this is about 2500 movies at nearly full light out.
I don’t know how much many hours you use your Pr. per year.

With private end-users, I would postulate the rule that the more expensive the projector is, the less it gets used. So 5K hours would get you many years of usage.

Now go to the entry level, and reason why some people made the very early move to all LED, and its low power usage and its long product life, they are selected to run all day (upto 16 hours) as TV replacements while keeping operating costs low.

And big Barco's at second, third, fourth homes, may get used once every couple of months.

Yes this is likely right.

Some WOW news about the new XXL V6 screen.

I have work on the screen the last few days and finish beside the masking everything.
Now it has a perfect tension and not any visible wrinkles or other bugs.

As I have to made new lens files as distance and size of the screen have changed.
So I working on this and to my big surprise I can focus very good to the screen that I easy can see
the pixels and the pixel gabs from the 4K DLP see picture!
I wonder as this was first time I can see with a fabric screen material pixels as sharp as a conventional screen without perforation!
Strange was also that I do not remember that my older smaller V6 screen I had test long time ago show this pixels at all!

As I still have some older V6 material I made a wood that contains the old and the new V6 material as you can see in one picture down the screen.
So I test it and again surprise I can see with the old one also the pixels very clear.
So this prove that I likely do not right focus when I have try the old V6 screen.

This is very good news for many people that looking for a acoustic transparent screen material that “not soften the picture”.
When you have a fabric screen that not  show the pixels this material soften the picture to some degree for sure.
This V6 material was the first that not do it!
It act like a conventional screen so it not decrease at all details and sharpness and not soften the picture.
This is “to my knowledge” the first fabric that act this way!

WOW!

Dirk do you can confirm this with your Pr. and screen?

Sound was much much better now.
Speakers was at the place they should be and more important was that they are now not at the floor and in the corners.
I have now a much better sound this I can hear easy with only one ear I have left.

Bad news was that I cannot confirm that this screen improve black level at least not the way I looking for.
True is that this screen show an about 20% dimer picture compare to the non-perforated Harkness Matt Preview screen material I had in the past.
And because of this the black level also decrease by about 20% but beside this there is likely almost not any further effect on cr.
Good is as I have the Barco Thor that I have enough light to comensate .
Sad I do not have any sample of the Harkness Matt Preview to made a new test about speckle but I am sure that speckle are very much reduced even
3D that show the most speckle are almost free now with this V6 screen.

Summary:
-much better sound as speaker are now where they should be
-no decrease in picture performance that some other fabric screen material all have more or less
-screen size increase a bit
-this screen kills speckle even at 3D to almost 0
-about 20% less light  (easy for me to compensate but if someone on the boarder that can be a problem)
-not much cr. improvement I had hope for

I will now see some movies and see if there is anything I further can report.
I hope it will be only good things.

All in all I was very happy with the output and hope the screen will do a good job for many years.

Glad to see the construction come to a finished state so you can now enjoy your theater again.
I know you have used a anamorphic lens in the past, is that picture with or without the anamorphic attachment. Ether way, Wow, razor sharp focus. Coming from a 4k projector and a 3 chip that is very good panel alignment.
Glad you are happy with the new V6 screen material.

When you use a ISCO 1.25 the pixels are not square anymore so this picture was without the ISCO 1.25 anamorphic lens but hard to see the 25% difference.

I did a screen shot only for posting here as there is so many discussion about this lens in the past from people had never try it and talk so much nonsense about it that I like to show this compare to the public. So I switch the Barco Thor on and did this pictures.

One picture show the Barco Thor optic with the Isco 1.25 anamorphic lens the other picture without the anamorphic lens.
Take a look at this picture and compare both.
You will easy see how good this ISCO 1.25 lens is as it show the pixels more or less in the same quality than without it!

I give people that doubt what I say since many years the tip to do this compare with any other Anamorphic lens in the market and see for yourself.
I say since many years that the “by far best anamorphic optic money can buy” is the ISCO 1.25 and different to other lenses you can not see any decrease in picture quality beside some distortions that are there no questions.

I say as a joke some times that the ISCO 1.25 anamorphic lens has in the corners a better picture that most other anamorphic lenses in the center and this is not a joke it is true.

But as always you need to understand the lens and much other things to get a good result.
For sample how to use the focus on the lens , how to place it in front of the pr. lens and how to focus the pr. lens ,how or if at what direction you tilt it and so on.....

BTW you need to go to the full resolution picture the preview is not good idea to rate it!

We watch at the weekend some movies.

At about now only 6.6 meter distance to my prefer row where I sit (the middle one) is it wise to going any further than 6.93meter wide that I can maximum without the ISCO lens?
0,95 times the screen back to the wide of the screen is for sure very big.
Even best 4K UHD Content is not made for much less than 1.0 times the screen wide in viewing distance.
So I will also try to shrink the 3D BD Picture from today’s lens file that had with 7.3 meter to 6.93 or even a bit smaller and see what looks better.

Bigger is not always better.

3D BD had not the quality that top UHD Disc have and it is still a shame that 3D in 4K at UHD is not possible but I strongly believe that it is just a question when this will comes and not if.
HDR is nice but “perfect” 3D add some big improvement to the picture that many of us like to see.

So a combination of 3D at high frame rates Rec 2020 or DCI Color 4K resolution with HDR with a top Display or Projector will be the goal.

UPDATE:
I had try 6.6 meter wide in 3D scope tonight and this looks better at 6.6 meter viewing distance than a bigger 3D picture.
Picture is brighter shaper and more easy to watch.
On top the distortions that the ISCO anamorphic lens have I use all the time for 3D are also smaller.

It depends on ones eyesight, I guess. Sitting (very) close with a very wide screen might affect ones periferial vision, so that might pose an issue before sitting to close for the resolution does. It might not, as people are all built differently.

The difference between the screenshots is indeed subtle, fully blown up, on my laptop screen. It takes clciking on the + looking glass and a good to llok to ee the different shape of the pixels in the first image. The line pattern is nearly as tight/distinct as without the lens.

[w.mayer]

Here a picture of the new finish screen at full 7.3 meter wide the maximum I can do.

[w.mayer]

Here 2 more pictures in 2 different versions one with and one without a the boarder but all with the old big guy

[w.mayer]

Here a last Picture.

[donaldk]

You are at least two meters tall aren't you;-).

You are finished, so time to start planning the tear down, for the next project, lol.

[w.mayer]

No it is time to enjoy !

[w.mayer]

No I am 1.83 meter only but very haevy

After a 2 weeks trip I am back to Germany.

I found a nice picture I like to post.
It show the V6 Material under very big magnifications.
There you can see the black very very small holes that show the black layer behind the front white layer when you view the full resolution version.

Next will be to adjust the convergence after changing my screen.
As I have to create anyway new screen files for the new bigger V6 screen I have this on my to do list since long time but I like to wait that the big V6 screen is ready.
Barco Thor had a very good mechanical tool that works very well so it should be not a big issue.
