Hmm, looks like I've mistaken, it was .95" DC2, not DC3.

Well, here's one person that agrees with you about black levels. I started a detailed response to be posted here, but got carried away and started a new thread: http://www.avsforum.com/t/1446906/how-to-achieve-the-optimum-perceived-black-levels.

Advertised contrast ratios in the hundreds of thousands, even millions? Bit of a joke, really.

cheers, got me thinking about painting my walls dark gray instead of black! although without lights in a light controlled room, all colors are black.
post #2734 of 3788
Maybe it's a misconception, but IMO absolute black levels is the one area that most of the lower cost projectors are lacking. Hence a lot of attention goes to this area. It's also the one feature/capability that they are still inferior to old technology (CRT).

Also, only maybe 5% of the scenes in movies, etc... really benefit from improved absolute black levels, so it depends a lot on what you watch. When you get a scene that does benefit though, it's a substantial improvement. An example of this that I use for testing is the scene in the original Stargate Atlantis pilot/movie where they first step through the gate on to another planet. I don't have a good camera for taking screenshots, but when comparing my W6000 with the iris on/off, or to my old Infocus X10, the W6k with the iris enabled has a huge advantage.

I also don't know where anyone came up with 1000:1 contrast for the W7k. It is clearly higher according to this site:

http://www.audiovideohd.fr/tests/318-BenQ-W7000-5.html

Low lamp is 2184:1 which is where it should be set anyway given it's brightness. That's pretty typical of a DC2, maybe a little on the low side. I think some make 2500:1. DC3 is around 3000:1 from what I've seen.

and here: http://www.hometheaterhifi.com/projectors/projectors-reviews/benq-w7000-projector/page-4-on-the-bench.html

I think the reviewer in the former review is an editor of the latter publication of somethingn like that, so maybe they use the same equipment??? anyway, different reviewers and different reviews as the numbers are not the same. I trust the collective subjective assessment more that such differing measurements anyway. And in that regard, the iris is much more concerning to me than black levels (primarily its proper function, but also its noise).

Any of those numbers are better than the projectors in the theater. Who knows which units with which firmware were used in the reviews.

My two projector setup is now complete! W7000 for TV, 3D and video games and my new JVC X55 for 2D movie viewing.

The overall look (skin tones and colour) and brightness goes to the W7000, I love the DLP look. Blacks and the WoW factor goes to the X55. When comparing 2D movie viewing the deep blacks really do help, IMHO. Any movie like Tron Legacy, TDKR etc. the X55 brings a whole new level of picture quality to the table and I believe it has to do with the blacks, everything just pops...in my room anyhow. Perceived or not, you can really notice the difference. If the W7000 could reach as dark as the 5020, HW50, or any of the JVC's it would be an incredible projector.

Maybe they can do this for the next model (W8000??) and with a 6x colour wheel and they'll have an all around outstanding projector. I've got my fingers crossed.

Just sold my W7000 but I am looking at the W1070 because it has a 6000hr eco mode compared to the W7000s 2500hr eco mode. I might wait to hear if the W7000 will be replaced with a higher eco mode because I love to watch my projector all day. The W1070 will have to be placed right above the screen, so I lose a lot of gain on my HP screen. It's an estimated 1.5 tho, instead of 2.1 I was getting with my W7000 right above my RS48/ X55. But a JVC and Benq make the absolute perfect set up, for the price, it would chose this set up over any led/ laser set up right now.

Congrats! I just got my replacement 7000 today which will find a nice home right below my RS45. Should be a fantastic 1-2 punch for 2d/3d.

Well, Ihave been enjoying my W7000 for a week or so, but now I'm sad. I was watching a movie tonight, and the picture started going darker every now and then. Now, I just turned on the NFL game, and the pic shifts from light to dark over and over again. Any ideas of what is wrong? mad.gif

After playing around with the settings, I can say that when the pic goes dark it's exactly like turning Dynamic Black off. This sucks!!!!!!!!!!!

That's the iris. Did it start working again after turning the projector off/on??
post #2744 of 3788
I now leave the iris off. It closed down on me once and the whining sound is pretty annoying. I don't really notice that much of a difference with the iris off/on. I know there is a difference, it's just the pros of having it off out way the negatives of having it on.
post #2745 of 3788
I leave it off too, not that important for me to leave it on when I only watched sports, ps3, and 3D

I cant get the pic to look right if it is off.
post #2748 of 3788
Well, Amazon 1-day shipped my replacement W7000, so I should pick it up tomorrow. I've got the broken one all boxed up to return to them. Hopefully the new one doesn't have a failing Dynamic Iris although I've seen so many with problems, I don't have a lot of faith. If the new one fails, I'll be returning it for a Epson 5020.
post #2749 of 3788
3 days ago I just bought and setup my new W7000 with Nov.2012 mfg date (firmware 1.00 - really?) and I notice two distinctly different fan noises coming from the unit.

One seems to be a normal, low pitch whir/woosh that I would expect from a projector. The other is an annoying buzzing, almost like how a light bulb sounds when on a dimmer switch - could this be a separate fan on the actual lamp itself? I am sitting 9 feet from the PJ and can still hear it in low-moderate volume scenes! I don't think it's the dynamic iris - I can hear that part moving if I get right up close and the buzz is still present if I disable it.

I notice when powering down the unit that when the lamp goes off, the annoying sound stops. Then the low pitch whir sound continues for another minute and then stops. The buzz does not change when switching to eco mode or from anything between dynamic and cinema modes - it is always present. I have read that fan speed will change in these different modes - making me think this buzzing is abnormal.

Can someone confirm that this is how their unit operates, please? or should I return for a new one?

Could be a noisy color wheel.
post #2751 of 3788
I think you're right on about a noisy color wheel buzzing. Did some research and that is really the only other moving part associated with the lamp being on vs off.

Contacted Benq CSR today and they said it definitely is defective and to exchange.

Thanks for your help!

I just got done mounting my replacement W7000 (2nd one). I set up the picuture per Home Theater settings for now. The setting call for Dynamic Black to be on, but I turned it off to see the difference and nothing happens. So, on or off the picture remains the same. The picture is amazingly BRIGHT, so I believe Dynamic Black is stuck in the on position. I guess that is okay since I want it on, but looks like another defective unit unless I'm missing something here. Time will tell if the Iris starts to act up, so I'll be keeping an eye on it. I do notice some slight squeeling noise when the scene changes from light to dark and back agian. Also, my old one couldn't seem to hold contrast levels very well. During football games the white hats and stripes on the ref's uniforms and the white painted sidelines would be seriously too bright to the point of blooming. This new projector is bright but no blooming. Anyway, my first initial thoughts on the replacement W7000.

Played around some more. I was using Component video before, but now I hooked up a 25' HDMI cable and reset the picture settings on the HDMI input. Watching a few things I can already tell this projector is definitely different than my last one. This one turning the dynamic black on and off doesn't really change the picture where on my old one the pic went dark and bright when off and on respectively. My old projector was really very quiet whereas the replacement W7000 is noisy. When I turn dynamic black on I here the iris moving when the scene changes. It makes a whistling shound. As soon as I turn off dynamic black the noise stops. I'm convinced my other projector was really messed up and this one is probably more normal.

What exactly does everyone else see when you turn dynamic black on vs. off? How does it affect your picture? I see no difference on or off, but on makes noises.
post #2754 of 3788
it gets a little darker when you turn it on, sometimes jarringly. but in a movie you dont really notice it too much, and i've gotten used to the iris squeak, so I just leave it on for movies.
post #2755 of 3788
I have a refurb w7000 on the way to compliment my JVC RS-45. So here goes another Benq + JVC user.
Here is hoping, no IRIS issues, no major noise, no broken color wheels, no defective lens assembly, no cracked/dirty/smeared lens, no busted lamp, no holes in the box, no broken remote, and I'll stop there smile.gif
post #2756 of 3788
There is a bit of a difference but it's not night and day, at least from my eyes. Like I said, I leave mine off because it clamped down on me once and the whining noise is pretty annoying. Other than the non-existent deep blacks, I love this projector. I'm hoping they correct this (blacks) for the next generation model. It's so close to being a perfect projector.

Playing around a bit more, the buzzing sound does increase in volume and pitch when I switch to dynamic mode compared to any other mode.
I have read the color wheel spins at 6x in dynamic mode and 4x in other modes. If this is actually true, then this also supports that the color wheel is the source of the noise issue.

Just thought I'd mention in case others have similar symptoms...

You have to understand how the iris works. It only closes down when the internal processor sees a scene that is dark enough for it to close. This is because it does 2 things, the iris closes (duh), but also as the iris closes contrast is boosted. This is the important part. If a scene is bright *or* has a very bright area in it, the iris does not close down since increasing contrast would cause blooming in the bright area. So turning it on/off with the menu displayed will have little/no effect since the menu itself is fairly bright.

Thanks for explaning. Now it makes sense about my first W7000. I'm certain now that the Iris wasn't changing at all. That's why everything was blooming and it was quiet. I never heard any noises at all like on the replacement W7000.

Just installed my w7000. Everything was going great until it came time to test 3d mode. I am trying to watch Avatar and when in 3d mode I get a black screen, when I go back to 2d mode I get two pictures (top and bottom)...
