So I guess we have to wait for a 'hands on' user evaluation, once someone gets their w1070 setup & running.

This is the spec:
Vertical 110%-130%±5%

note the ±5%

This means that in the "best" scenario, the image will be 5% above the center of the lens at "minimum image shift" but it could be as high as 15%. Same goes the other way, you could be able to shift the image by as much as 35%, or as little as 25%. On a 120" image, 5% = 7.5cm (this is in the benq manual)

Kraine:
"It's a very small vertical lens-shift and it's working only in a positive way + 30 cm to the top from the center of the optical engine."

He tested W1070 on 100" diagonal screen. So, something wrong...

Just got off the phone with NCIX, they are shipping to the US and it should go out today or tomorrow and arrive by next week. Cant wait, been putting off getting a screen to see how it looks first ( although I will have to come up with something for testing since my walls are very dark.

I am following Kraine in his website, and here are some notes that I concluded:

- Kraine said W1070 3D is in level with HD33 and Acer H9500bd, which is means in same level of BQ W7000. He gave W1070 low score because he said pop out was not as good as Sony HW50ES. I hope BQ glasses were the reason for his comments.

- Projectors being shipped are firmware 1.2, while he tested firmware 0.8, Hope we see good improvement.

They may ship yours fast but they are damn slow to ship mine! Still waiting and they apparently began shipping them on Wednesday..

Oh I knew what you meant (I think lol), but I think we're both talking about different projectors? The W1070 you are alluding to has lens shift and the short throw version W1080ST does not have lens shift. I was hoping since the W1080ST has no lens shift that it would at least have a higher offset so it could be ceiling mounted closer to the top of the screen, rather than near the middle where it might block the view.

So that means you can only move a 120" image 7.5cm up? That's only like 2 or 3 inches? That's very small :-/

If this is true, ceiling mounting could require hanging the projector very low.

As an example, a 120" diagonal screen has a height of 150cm. Let's assume a 20cm drop from the ceiling to the top of the screen (to account for the screen housing). Ignoring the ±5% error tolerance, at max projector shift of 130%, the center of the projected image would be 45cm below the lens. That means you'd have to hang the projector 50cm below the ceiling, in order to put the center of the projected image at 20+(150/2) cm below the ceiling, to match the screen.

A 50cm projector hang is almost 1' 8". Not pretty.

Real owners: please confirm this!

No, the range is 110%-130%±5%, so around 20%. This means ~30cm or so

The 5% that I've mentioned (ie: 7.5cm for a 120" screen) is the OFFSET for the BOTTOM of the image from the center of the lens. This is as per the BenQ user manual.

Kraine's testing of the lens shift appears to differ from the user manual, and there is a German forum where I read (translated google chrome) a guy has recently bought the w1070 and he got 5cm lens shift with a 1.9mtr wide image..........

hello people, now I can only tell my subjective feeling .. I find the picture just awesome, my wife thought it was really hot so the picture,,, rainbow effect, I can not see, volume in eco mode for me very disturbing, the only thing that disappointed me a bit is the lens shift .. 5 cm high and 5cm down ... pictureWidth the moment approximately 1.90 m ... but since I have space, it's not so tragic. BENQ w1070 was the right decision even if you get more money for even longer, but does not necessarily have :-) Greetings Salewo

after my wife found it visually beautiful, I saw him once connected and times projected from neurgierde beige on my glattverputzte cellar wall. canvasneeds to be assembled. 've now grad times sky hd watched football and now ne round played fifa ... top it all, the feeling says ..

Page 10.... http://www.hifi-forum.de/viewthread-94-12408-10.html

By the way guy's, I've had the W1000+ for 2 years now (just changed the lamp) and it's pop sharpness/brightness used on eco mode, I am still very happy with it, 1080p is awesome, runs quiet and I don't see RBE.

Hmm.. 1.9m wide means that he's got a 1m high screen. 5% of that is 5cm so he's only getting a total of 10cm travel (10%). Definitely not much. I hope that the pj mount I bought from monoprice will suffice since it's really short.

I was complaining about the same thing. I checked the calculator on BenQ's website and it said I had to hang the projector 18", which is going to look ugly with my 8 foot ceiling. If you factor in the height of the projector, its going to be hanging about 6 foot above the ground. Which means any tall people are going to be running into it LOL. No way my gf would approve of that rolleyes.gif

After staring at the W1070 manual, I've concluded that their description of the lens shift feature is terrible. smile.gif

The truth appears to be this: when ceiling mounting, the top of the projected image is always below the lens. How much below depends on the lens shift: the vertical distance from the lens to the top of the image can be between 5% and 15% of the total image height.

In my example above for a 120" diag screen, the image height is 150cm, therefore the vertical distance from the lens to the top of the projected image can be anywhere from 7.5cm to 22.5cm.

That's much better!

Yeah, the manual sucks for the lens shift! It took me a few shots to understand and even then... my understanding matches yours (except that I believe that the shift goes to a minimum of 25% height, ie the 30% - 5%)

So we will probably see the W1070+ early next year with better offset/lens shift which is typical of Benq. You would think they would get it right before they knock em out the factory lol smile.gif

The figure on Page 20 is the key. The top diagram shows that "100%" refers to half the screen height. Then, the vertical offset from the lens to the edge of the projected image is shown to be 10%-30%. But remember 100% refers to half the screen height, which is incredibly confusing. If you instead refer to the full screen height, then the offset becomes 5%-15% of the full screen height.

I did read somewhere ( I will need to check) that the W1070 had more than one fan, but I will need to clarify this, so don't hold me on this one.

It's not clear which parts of your post are your own comments, and which are quoted. Try editing it to use the forum's quote feature (the " toolbar symbol) around the quoted parts.

Very confusing but I think I get it now....

Regardless, I think anyone who is planning to ceiling mount is going to need a long mount frown.gif

I don't think so, but it depends on how low you want your screen to be. Here is an example. Let's assume use of a short 6" mount. The W1070 itself adds almost 2" (distance between mounting surface and lens center). For a 120" diag screen, that means the image will be between 11" and 17" from the ceiling (approx). That's pretty low. I think it would fit most installations.

I ordered mine last late last night, and I just received shipping info, that was quick. I also updated the my earlier comment, Kraine mentioned very good informations.

I sold my W7000, and I am more excited to get this due to newer technology and cute size and weight.

Very excited to hear your comparison of the w1070 and w7000. I'm trying to decide between the two.

I don't see how the W1070 could be better, except for form factor!

dark chip 3 instead of 2, 6x color wheel instead of 4x, brighter in both 2D and 3D, large improvement in native contrast. I DO see how it could be better! almost sounds too good to be true so I'm eagerly awaiting reviews.

Here's my scenario using the BenQ calculator for the W1080ST:

screen size: 120" screen
ceiling height: 8'
distance from projector to screen: 6'
distance from ceiling to screen top: 1' 6" (screen mounted 1/3 eye level)
distance from ceiling to projector: 1' 5"


So according to the calculator I would need a 1' 5" (17") projector mount to achieve that setup. Add in the projector height (maybe 5"?) and it's like a 22" drop from the ceiling, which for a room with 8' ceiling, it's kinda in your face lol.
