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

[dirk goetze]

Finally 2 weeks ago, I get back my Lumagen Pro from the well known Oliver, with 2 new set ups using Intensiv Tone Mapping and one for 1080p.
The ITM Feature lift my VW 1100 up, its still a step away from 760, but now I start enjoy 2020/HDR by press a button and using the tool.

Your Right Wolfgang the netflix colors of "2001" look a bit better than the BR Version. Funny they have used another Master?

This week they announced to move the release of the UHD from may...closer to the date of the cinema premiere ago.
If someone is in Frankfurt during the summer check this out  http://2001.deutsches-filmmuseum.de/

Meanwhile in May will "Gladiator" being released at UHD, hopefully in real 4k, not upscaled,  I find no informations about so far.
I really like the Movie after all those years!

Some update after long time.

I return it finally the matrix.

The color banding bug was gone but the new version had big problems’ with the Oppo UHD player when the Oppo output 1080 P.
Also Apple TV do not work perfect with this matrix.
For sample I like to see one older movie "Falling Down" but no BD was there only ITunes have it.
So I rent it for just few Euro and bingo a very good picture quality but heavy motion bugs.
Later I found out when the matrix is in between the Barco Pr. and the Marantz that I cannot output 24P in 1080 with the matrix inside!
It only allows 50P and 60P output but as the sources was in 24P you will understand how bad motion looks.
Apple TV direct to the Barco or to the Marantz works fine I can adjust 1080P in 24P without any problem with the Matrix not.

So I return it as there was so many bugs with this matrix that I do not like to spend any more time with it.
The few times I watch 4K 3D slides I will disconnect both HDMI cable from the Barco Thor and put both from the 4K 3D computer inside and return this when I am finish.
That is not such a big issue for me and better as running into many problems with HDMI handshake problems.

Next week I will work again about the big V6 screen to see how I can set them up in front of my existing screen.

JUMANJI: Welcome to the Jungle, while not a 4K title looks great with lots of HDR and good color. Good entertainment.
“The Great Wall” is a 4K title with really nice colors and outstanding transfer. Highly recommended.

It looks like after long time that I found some good solution to replace my screen with the V6 Screen Material.

The plan was to put the existing screen material out but let the frame structure as it was.
As my screen was 12 years old I anyway have to replace it sometime in the near future so cut it out is not a big lost.
This also allows me if I am not 100% satisfied with the new V6 screen to put a new Harkness Matt Preview back in a relative easy and cheap way.

I have order 3 new front speakers that have only 20cm deep and I will put them with some distance to the wall behind the screen.
Then I will make a new wooden frame that are attached to the room walls at this place with about 3cm thickness in about 35 -45 cm distance from the wall behind that will have the plastic parts that comes with the V6 Material for mounting.
This Frame will be Left Right and Top will be fix the bottom will be in 2 parts that I can movie when I need to going behind the new screen just in case something is with the speaker.
So the new screen will be with a boarder about 3 cm from top to bottom and left to right so fill almost 100% of the possible size the room have at this position.

So my screen will be get a bit bigger.
I think it can enlarge from today 7.0 Meter to possible 7,35 and the height will be increase from today 2.85 meter to 2.9 meter.

Speakers will be coming in 2 weeks and I think all the rest need 2 weeks more if everything runs well.

With the frame to the side wall instead of the back wall another option  would be fixing in to wooden beams screwed to the wall. Tensioning is done by a cover placed over the screen and beam. By mounting the beam to the sidewall the cover that clamps the screen can be an L shape instead of an U shape as when the wooden frame is screwed to the back wall. This allows for the biggest screen. By covering this screen pushing edgecover with velveteen, and making it wider this could act as a anti reflection box, like the one in Turkey, Hyperion.

Glad to hear you have a screen solution for your theater room. I have compared the V6 to the previous V5 and the 6 is noticeably sharper. Nice to hear you are moving your speakers behind the screen. The front of your Theater room will look more open and larger.

Looks like big cinema screen manufacturer Servertson  now enter the fabric screens at least for medium big cinemas
with almost 5 meter high screens see here:
https://www.dcinematoday.com/dc/pr?newsID=4975

So about 9 meter wide in 1.85:1 is possible and over 11 meter with 2.4:1

thats good news Wolfgang, I look forward to your impressions. I have the V6 for a while, but only 3,8m wide and 1,6m high. My cinema is in the Basement 2,04m high only. So I attept this genius solution (covered in the celling and in the ground) from Nils, because I really wanted deep curved and ended up 45cm/ 18" in the middle, thats nearly Cinerama
"bow" for my screen

Maybe is useful for you to

That is interesting to read as I was thinking to do as well a curved screen!

Reason why I not plan it was the less good cr. you have when you curve your screen “at least in theory”.

Just let think what happen if you have a curve screen compare to a flat screen.
Let’s say the picture was left half 100% black and the right half there was some very bright parts inside.
So in this case as this screen reflect almost 180° the light back in all directions some of the light will hit the left part see my hand drawing!
This will be decrease ansi and or both on off cr. as well.
At least in theory!
Because I am worry about this I not plan a curve version but on the other side I really like a curved screen.
So maybe the V6 material act different to normally screens.
But may this curve kills the biggest advantages this V6 screen material have "to show a better cr.".

The only way to find out if this is the case or not and if how much it suffer is to build a small test screen let’s say
1.5 meter wide in a curved and a flat version and take a close look having them side by side.
If there is not any visible difference in cr. that you can see curve is for me an option as well.

A nice side effect is that because of the small iris in the Lens my field of deep is very huge so I can heavy curve it without looing focus.
I test it out in my case I can go more than 40 cm at both sides to the front and still focus in center is perfect and on the side as well.

Don’t know if on both sides 40cm is the right curve angle but at least focus looks like is not any problem at all.

We should discuss this more in details and any value info on this are welcome.

That's funny, what you also thinking about a curved screen.

But I can't help,because I only movie geek and my technical knowledge is limited. I read a lot , since 4K/2020/UHD came out and try understand most of it.
I can do no measurement etc.
The Reason I change my  Fabric from Seymore XD to the V6, was the upsence of visible structure, so I can move my seats closer to the screen 
All I can say is I really like the effect of the curved screen, so I gained the curve with V6 to 45cm/18" deep.
My chain is Oppo 203/4K ATV to Lumagen Pro with ITMapping/scaling to the VW 1100 + Isco 1.25 Lens placed in the nearly in middle 4m away to use max brightness, the picture is still sharp in corners.

The only con is still a none constant height picture size, over the full screen wide, I lost 6 cm down and 4 cm on top, because of deep curvation.
I will correct this with the 4K Version of the VNS Warping Geobox as soon it comes out....hopfully in 2018!

I think Oliver Klohs can help you, he did a great job by calibrate my VW 1100 / Lumagens Tone Mapping by using a big sample of V6, he still have it.

I talk to many people about the issue that a curved screen had some less good cr. visible compare to flat screens.

The people I spoke are beside Oliver  all retired cinema people with at least each 40 years of experience.
It is very simple as no one can change physics.
There is light coming to a screen part that show a dark picture like in my hand drawing.

The only difference is how much gain factor a screen have.
So in cinema they use mostly 1.8 to 2.5 gain and there the light was much more reflect back to the viewer and less to the side.
So in cinema this is not a big issue and on top cr. in a cinema is typically in the 500-1500:1 cr. range because of Exit sign and many other things so a curved screen will not change this very much.
In home cinema with a screen like the V6 it is opposite.

So you can say in general about this issue:
”The more gain a screen have the better as it not ruin your cr. when use a curve screen the less gain your screen have the worse it will”

Again this is based on simply physic but it was also proved by some statements I got from people that do hundreds of screen the last 40 years.
As improved cr. is one major reason why I like to try the V6 I will do a flat version and not a curved one.
I will not doing tests about this as this will only take my time and I know the outcome already.

Sad as I like the curved version a lot but as always there is most of the time a trade of.

Similar to my Projector the Barco Thor when you like high on off cr. you lose almost 50% light to double the on off cr. number.
This comes on top with my lost for the new V6 screen that will be about 20% darker!
For all 2D include UHD HDR material a no issue as I drive the Barco Thor in the good 50% Laser power only so I can easy compensate the -20% lumen but for 3D I will suffer as my 20FTL will then going down to 16 FTL.
But I will see a speckle free image with a lot better cr.
From my tests I did cr. looks visual ratet at least about double as good compare to my Harkness Matt Preview that I today use.

Thanks for clearify Wolfgang,  your arguments make absolute sense.
In your VERY extraordinary Cinema the whole "problem" is lift to another dimension.
To name only one: our screen is TWO times wider than the 90% of the rest of big home cinemas and so one.
I also forget your passion for 3D, the THOR is outstanding, but all the points you listed above saying stay flat !

I my case I always looked for the a deep curve AT screen, with closesed possible viewing distance.
The V6 and 4k give me a big step in that direction.
20% loss of light 0.81 Gain and physical loss of contrast in same scence i have to live with....the ISCO 1.25 Optic and the new IToneMapping from Lumagen help to enjoy UHD movies now...until I have to change the lamp of my VW 1100 again.... 

[w.mayer]

New very flat (only 18 cm!) custom develop 3 Front Speakers that comes behind the new V6 screen are almost ready see pictures.

Let’s see if I can get it this week or soon after eastern.

[MrPixels]

Very nice looking custom speakers. The shallow depth is very rare, a nice feature for a home theater system.

What are we seeing in the third picture? I see a heat sink, are these the amplifiers?

[w.mayer]

Yes this are high end digital amplifiers as all my speakers are active.
