Well Spectracal v5 has some nice features, but Chromapure is more straight forward and to the point and seems to be what most in here prefer, although some of the Pro's tend to use both sometimes.

Thanks for the input.

I've been using Fork HCFR, which is free. I can't justified spending $200+ on Calman or Chromapure, for such little usage.

Great, thanks a bunch!

 

So to perfectly clear, a 46mm photo filter will fit nicely onto the lens housing?

 

3 more questions if I may:

 

1) is there any pumping effect in smart-eco mode? some say yes, others no so that's confusing.....maybe those that say no are rookies, who knows....so to be perfectly clear if you watch a dark movie(matrix, spiderman or so) can you see sudden brightness changes in dark/bright scenes changes? Usually these things are laggy but a recent review says that smart-eco isn't dynamic whatsoever, huh.

2) is there any "neutral" sharpness setting? apparently there isn't on the w7k, it's either blurry or sharpened duh.

 

3) Is the CW whine pitch very different between 24Hz and 50Hz? A wild guess would be that it outputs it in 48hz so the pitch difference should be barely audible when OTOH 60Hz should be a quite lot higher.

1x refers to the wheel spinning as many times in a minute as the screen refreshes. Hence 60hz multiplied by 60 seconds gives 3600rpm. For a 3x wheel you multiply that by 3 and get 10800rpm.

For 50hz it refreshes at 50 times per second. Multiply that by 60 and you get 3000rpm. Multiply that by 3x and you get 9000rpm.

Therefore:

3x at 60hz = 10800rpm
3x at 50hz = 9000rpm.

They are different speeds yet still rated the same way.

Now read my point 3. above again.

The question that had been asked was if the W1070 changed speed when you changed viewing modes (ie Dynamic to Cinema as per the W7000) NOT whether it changed speed when you changed the refresh rate because ALL DLP's do that. It's just the way the technology works.

I actually mentioned that it was quite obvious that the wheel speed changed when changing refresh rates and the fact that these effects DID NOT occur when changing viewing modes leads me to conclude that the projector does not change from 6x to 4x when changing viewing modes.

I know the "normal" speed changes between 50hz vs 60hz but if read my post carefully you see that 50hz 2D is faster then 60hz 2D/3D and it's quite a lot faster. 60hz 2D/3D is same but 50HZ 2D is fastest wheel speed with 24hz 3D and 50HZ 3D is slowest with 24hz 2D.
What i meant about modes was actually different refresh rates not display modes of projector. It's not 3X for every refresh rates for sure but there is no changes when cycle through different modes of projector(dynamic, cinema etc..).

I think that price is what it actually was supposed to be all along but initially it was set higher to get a few extra bucks. That's why it was cheaper in Canada.

Just pulled the trigger on the Vapex package deal with the W1070, 120" tab tensioned screen, ceiling mount, dust cover, calibration disk, universal IR remote and a 35' HDMI cord....under 2K tax and shipping included. This will be our first projector and the family is excited. I had been watching the Epson 3010 and the 3020 but this deal just seemed to good to pass up. This bad boy is going to look great when it drops down in front of the lil' 52" Samsung.

Actually ran my verniers over the lens for you since if you're going to be basing a purchase of this I should do a bit better than a tape measure.

The inner mechanism is 44.72mm in diameter. Around this is a void. The outside of this void is approx 52mm (sorry, calipers couldn't fit into the recess).

So if the locking ring of your filter has an inner diamter of greater than 44.7mm and less than 52mm you should be able to slip it over the lens mechanism.

Please note that there is no way of screwing the ND filter onto it as you could with the lens in the VP4001. The cheap lens on the W1070 has no provision for this. (click on the image below for dimensions)



I'll try to adress your other questions later. I need to do some specific testing especially with regards to the "smart eco" mode.

Well I ran some tests tonight to try to understand the “Smart Eco” mode.

For convenience I shall refer to the 3 modes as Smart, Low and High.

I used a PC running a Powerpoint presentation in full screen mode alternating between full black and full white screens.

I pulled up the settings menu and changed the lamp power from Smart to High on both the black and white screens and noticed no change between these modes on either the black or white screen.

I then performed the same test alternating between Smart and Low on each screen. Each time (either black or white) the Smart setting was considerably brighter than the Low setting.

It then occurred to me that perhaps the brightness of the Settings menu was causing the PJ to use Smart mode at High brightness.

Luckily there is a way around this.

The Enter button on the remote cycles through the various picture presets and only brings up a very tiny grey and blue text on the top left of the screen. I set up the various Picture presets all the same (50 Brightness, 57 Contrast, 7 Sharpness, NR off, BC off) but alternated the Lamp settings from Smart to high. Therefore everytime I pushed the Enter key it would change from High to Smart.

As you would hope and expect, doing this on the white screen produced no change in the onscreen brightness. On the black screen it was a little more interesting. As you change from a High mode to a Smart mode initially there’s no real change. But as soon as the text up the top left disappears (to make a completely black screen) the image darkens quite perceptibly. This same effect must be happening when in Smart mode and I change from the full white screen to the full black but the lamp must be able to adjust faster than my eyes making the process imperceptible.

So yes, Smart Eco does do something. But I could only see it through conducting a test designed to make it as visible as possible. I am yet to notice it while watching video content and seeing how difficult it was to produce a test that allowed me to observe it happening, I can’t say I’m surprised. Interesting that it considers the brightness of its own menus when adjusting smart mode rather than simply adjusting for the source.

So it sounds like fade to blacks should be improved with smart eco on.

I suppose so yes. But it never dropped the black level below that of Low. So it seems to ajust bewteen High and Low but doesn;t extend the range. I'm not sure how its supposed to save bulb life over Low?

Yeah, I am also still not sure how smart eco is supposed to save more bulb life than the Low setting. Everyone seems to say it's brighter.
On a side note, I just cancelled my order with a different dealer where it wasn't in stock & ordered from Visual Apex where it was $70 cheaper.

I'm also wondering how lamp life is increased over eco but maybe there is more aggressive cooling variation then eco. At least when room temp is low, Smart eco produces brightest image and is also quieter then eco. Maybe when temp is high Smart eco mode spins those fans faster and reduces lamp power also? Haven't test Smart eco too much so far but it seems to be quite good if room temp is low. Will check this with service menu, there is fan speed monitoring and target speeds.

I think there is a more aggressive cooling variation in Smart Eco mode. Trusted Reviews seems to think the same thing.

Second, when using the Smart Eco setting you can occasionally be distracted by a slight adjustment in the noise coming out of the projector if a) you're watching a quiet moment and b) you're sat fairly near the projector. Though to be clear about this, the W1070 is by no means a noisy projector generally considering how small and cheap it is.

Another W1070 lens shift question for those in the know:

Would like to replace my aging Epson with the W1700 but my room situation is unique and I don’t think the lens shift will be enough to work -- but I’m not sure my calculations are correct.

For my current setup, I have an 8ft ceiling with a 120in screen hung 4in from the ceiling (white of the screen starts at 6.5in from ceiling). In order to get that 120’ screen with the W1070 I would have to mount it to the bottom of a duct that runs across the center of the room. The duct is drops 1ft from the ceiling, so the center of the W170 lens would be about 9in LOWER than the top (white) part of the screen (if I can mount the projector flush against the bottom of the duct, without a celling mount. Which shouldn’t be a problem).

My (likely dubious) calculations tell me that, if mounted this way, with the lens shift at it most extreme position, the image will be ~9in from ceiling, just about exactly where I want it to be, but leaving 0 margin error.

Can anyone else confirm that with a 120in screen the W1070 (mounted upside down) can shift the projected image at least 9 inches higher than the center of the lens?

BIG thanks in advance!

Josh

I sat down with a Benq rep at CES and he told me that he thought that the SmartEco mode was a better method than Dynamic Iris for improving contrast and black levels because it was faster. I've looked for a white paper on this but have been unable to find anything. I didn't know these bulbs had that kind of speed in their design.

I'm still confused about the lens shift on this pj. What is the maximum offset that can be obtained using lens shift? From lens down to the top of the screen. Is it 2.5"? Or is it 7.5"? I'm projecting onto a 106" screen from about 9'away.

I wonder if when the bulb is doing the black level adjustments, instead of BenQ using a mechanical iris, that this might tax the bulb? I would think that if the bulb is always being driven at different brightness points, when in Smart Eco, that the life of the bulb might end up being much shorter. Who knows? Since this is a new projector with a new way of dealing with contrast, I hope it works as planned.

What's not to understand? It's ~10% of the vertical length of the screen/image.

So if you have a 110" screen, your vertical length is 54" (assuming it's a 16:9). 10% of 54" is about 5.4".

Someone rightfully corrected me on this about 10 pages ago. BenQ actually uses 1/2 the screen height to calculate offset, therefore 10% is about 2.5" in the example given.

Anybody still on the fence about this projector might want to check out the Visual Apex package deal; w1070+92" tab tensioned screen w/wireless 12v trigger+35' HDMI cable + mount+Disney WOW calibration disc+ some other incidental goodies for $1,500.00. Larger screens are available at a higher package price. I have been waiting to buy an Epson 5020 but this kind of package deal is hard to ignore.

Got this to replace my old Optoma HD70 which FINALLY had it's bulb go with something like 6000 hours on it.
At the same time I picked up a Sony BDP-S590 (?) to go with it, Costco is also carrying I think the same thing with different model number.
Tried out the Sony streaming off the media server on my NAS onto my LED TV and for some reason the picture looks way better than
my other media player boxes. Seems to handle everything except ISO's of course.

My first time ordering with NCIX and I am really impressed. Well packed, prompt shipping, seems like they have a good system for notifying you about your orders.

Anyways first impressions.. very bright compared to my old projector. Too bright on 2d even in econo mode, 3d is plenty bright in a dark (not light controlled) room.
Seems quieter but don't have it on the ceiling mount yet. I have a 96" screen but planning on maybe going to a 120" as this can throw a bigger screen from the
same distance compared to my old projector hopefully that will help with the brightness.

3D is kind of interesting to get going. The Sony player has some very nice hidef frame packed streaming 3d demos available if you have > 10Mb internet.
They worked great out of the box along with the 2d->3d conversion feature on one of my blu-rays (also nice as the projector doesn't convert)
3D seemed a little underwhelming at first but it seems to depend a lot on the source content. Some things looked fairly flat and others
jumped out at me. I think maybe a more light controlled room would help without all the visual clutter around the screen.

Where it gets interesting is when you are dealing with other 3d sources. So.. for example to view SBS video on youtube or the internet video search feature
you need to set the player to output 1080i or lower otherwise the SBS option is not available on the projector. That said, the resolution SBS 3d provides
is just not enough for a screen this big. It's like watching video off the internet 10 years ago. Will try it with some SBS mkv files, the streaming
is probably aggravating things although I do regularly achieve 40+ Mbps off the net.
-- update: SBS mkvs are quite watchable about DVD quality which is about what I would expect. Not sure what the deal is with the online content

When I use the DLNA feature to play my MKV files off the media server turning on the 2d->3d conversion on the player gave the projector fits
until I lowered the resolution down to 720p then all was well. Seems like maybe projector needs 720p for top and bottom and this is what the
converter outputs ?

Anyways took me a couple hours to figure it all out and it's kind of a pain to switch your resolution back and forth like that but it all works.
Maybe when I get around to running everything through my receiver I will be able to configure it to switch resolution with a button press but more likely
I will just have more issues. Thought I'd share and maybe save everyone some time fiddling.

Looking forward to someone posting some nice calibration settings to start with.. I think the default settings need some tweaking.
Also I am interested in maybe picking up a filter depending how things go... not sure what size I need?

Hi Tailslide, how did you get the Sony player to convert 2D to 3D to play on the W1070? When I pressed Options on the player's remote, I didn't get 3D menu.

Does this projector have horizontal keystone correction?

I know that deteriorates the image, but since I'm considering this as a second projector for odd jobs, I'd like to know if I can offset it or if it has to be centered with the screen in all setups.

The BenQ site only says it has vertical keystone, but this guy mentioned horizontal...

http://www.projectorreviews.com/game-projector-blog/review-benq-w1070.html

Edit - Nevermind. I found the manual online. No horizontal keystone correction - only vertical.

I’ve just read this thread through from start to finish and there are a few recurring themes/questions. I’ll try and deal with them one by one:

1.Menus: Picture adjustment menus remain open if you access them through the setup menu and do take up a bit of screen space. You can however adjust basic picture settings such as brightness and contrast using the direct button on the remote and this only displays a slider bar towards the bottom of the screen.

2.Tint Control: Video controls such as tint are greyed out when using digital signals. This is how it should be as “Tint Control” is only relevant to analogue NTSC signals which are susceptible to having the colour information slightly out of phase with the remaining picture information thus producing incorrect colours that are particularly noticeable with skin tones. In the digital world this is not possible and any issues with skin tone are due to other issues which need to be addressed in other ways. The W1070 has excellent calibration controls in order to do this.

3.Colour Wheel Speed Consistency: Unlike the W7000 I believe the W1070 remains at 6x speed continuously. I tried switching between low power Cinema mode and high power Dynamic mode and there was no audible difference from the colour wheel. Also, the W1070 takes a split second or so to syncronise with a new colour wheel speed (changing from 50hz to 60hz or 24hz) and displays flickering while this occurs. I believe that if it was changing from 6x to 4x it would not only be audible but visible as well. I neither see nor hear any sign of this.

4.Colour Wheel Speed:
  • NTSC is 60hz (60 times per second) = 3600 times per minute
  • 1X wheel speed = 3600 rpm
  • 2x wheel speed = 7200 rpm
  • 3 x wheel speed = 10800 rpm


There is nothing faster. To get multiples of these manufacturers add second colour elements to the wheel so the wheel is rgbrgb thus doubling the effective rate. This is how it’s always been done and as such it is a “true 6x” wheel.

5.Lens size:
  • Diameter of Outside of plastic housing = 45mm
  • Diameter of Inner section of lens including black plastic ring = 38mm
  • Diameter of actual glass = 33mm


Sorry. Never fitted an ND filter so don’t know which measurement you need.

6.VP4001 Comparison: Coincidentally I’ve just replaced my Marantz VP4001 with this projector. Unfortunately the reason I replaced it was because mine stopped working so any comparison is from memory rather than a true A/B comparison. The projectors are very similar in that they are extremely sharp and very bright (VP4001 was one of the brightest home cinema projectors when calibrated). I’m sure the lens of the VP4001 was superior but the W1070 can resolve a 1080P 1:1 test pattern virtually perfectly and doesn’t suffer from much chromatic aberration at all. Certainly nothing visible from a normal seating position. The W1070 displays far more detail than the 4001. Textures on peoples clothing are clearly evident. Skin tones seem more natural and I’m pretty sure there’s more shadow detail but without doing a proper A/B I wouldn’t bet my house on it. If you like your VP4001 I’m sure you’ll like the W1070. Is it worth an upgrade? I’m not going to make that decision for you I’m afraid.

7.Light leakage. Pretty bad and off horizontally to the left if you have the PJ ceiling mounted. It comes out at roughly 45 degrees so will more than likely be on visible on your side wall.

8.Firmware: My firmware is 1.02 and I have not detected any flickering.

Hope this was of assistance. Any further questions I’ll be happy to answer (so long as it doesn’t relate to 3D, computers or gaming). I’ll try and work up a bit of a review over the next few days but I really need to watch it some more first.







I own the vp4001,thinking of getting the1070.How does the benq's black levels compare to the vp4001?

Can anyone help me? I have the w1070 (which I love) but I can't get to play blurays in 3D and it's really starting to annoy me. I have the sainsonic glasses whch work fine with xbox 3D but with the Judge Dredd bluray nothing happens. The projector understands that it has a 3d source and displays that info at the top with frame packing selected and the bluray image is blurry and looks like it should be 3d but nothing happens when I put the glassez on. What am I doing wrong? HELP.....

Hi all,

I made some tests concerning the triple-flash (144Hz) discussion: I used Nvidia TVplay and viewed 3D with 720p50Hz, 720p60Hz and 1024p24Hz on my PC on the W1070. My observations:

-720p50Hz: Strong flicker (like on my Sony HW50 which has 48Hz per eye)
-720p60Hz: Greatly reduced flicker, but still visible when viewing during day-light.
-1024p24Hz: Flicker practically non-existent and even more reduced compared to 720p60Hz.

This makes me convinced that the Benq W1070 uses indeed triple-flash when viewing 1024p24Hz content (Blu-Rays), which is quite spectacular at this price point.

I think the problem might be with the glasses. The Benq supports 144kz output for Blu-Ray. Older Sansonic glasses might only support 120kz. The white ones will not work. The latest black ones that support 144kz will.
