Yeah, I agree. Many factors come into getting long bulb life. And I think everybody should get UPS battery backup, VERY IMPORTANT POINT , so lighting strike or power outage doesn't put lots of stress on bulb or pop the bulb. I guess I was thinking more of epson having really short bulb life of 700 hours a while back compared to 4,000 paper spec. I'm not saying the benq will have this problem at all, but , we will not know how long the bulb CAN last from user experience until owners report back that info. But if the PJ is giving the wrong hours , it could be hard to judge how many hours someone does have on it.

Many things will determine if wanted or not. Screen size being maybe the biggest then screen type, room color and lighting etc. Larger the screen more lumens needed so less likely want a ND filter. Have a high gain screen again deppending on size may want a ND filter.
I use it to bring the brightness down. On my 100" screen with a likely .9 gain screen it is very bright and a ND filter brings it into range. Blacks do get darker but also the eyes are not as strained.

Thanks - I have a 100" Screen but really feel no eye strain, whatsoever, with a 1.3 gain, SmartEco, Cinema and Brightness between 45 & 47. Maybe it's the SmartEco that minimizes the brightness or potential eye fatigure? I'm also used to a bright LCD/LED 65" set - so maybe my eyes are used to that type of light.

All I know is that it's hard to go back to a smaller screen once you've stepped up to the wonderful world of projectors.

Regarding the fan noise others have reported, does anyone else have this sort of noise: https://www.dropbox.com/s/g02pgsv7mxb8qnj/W1070_fan.m4a

This is exaggerated as I had the mic right at the fan, but I can hear the chugging sound from 3m away. I'd say it is around 4 times louder than the moving air noise. Was looking at two of these PJ for passive 3D but would be intolerable if this was twice as loud.

This is concerning... considering contacting BenQ just to see how they approach it.

1) Maybe they are factoring in lamp strikes?

2) Or perhaps the clock thinks it's running on 50Hz power instead of 60Hz.

How do you update this projector? Is that what the Mini USB port is for on the back?

many manufacturers such as Epson & Panasonic...etc already introduced or will soon introducing the successor of their previous year projector, wondering any chances BenQ will do the same for W7000?01.jpg28.jpg03.jpg

1) I considered that but the counter continues at the same pace the longer the projector remains on, not a one time addition (at this rate it would be billing us ahead of time).

2) I am no expert on that theory but would that not be 20% faster at the most, my tracking shows 33% (interesting idea however).

I could be totally off base here but I have a hunch there is possibly some marketing at work regarding this issue and this is no bug.

I am going to send BenQ an e-mail soon to inquire and see what they have to say.

Great input though, thank you.

I have joined the club now.

As for fan noise? Cannot hear it above the built-in speaker when playing TDKR. The Benq is on the table <3 feet away. PS3 as BR player.

My first projector after ooohaaahing for a few weeks. Brilliant pic for the price and PORTABLE.

LOL, ATM am projecting onto a beige coloured wall! I could have gotten a 55" LCD TV but the physical and display size of that would be silly compared to this for a similar price. A cinema in my own living room.

Now to consider which eBay 3D glasses to buy. I did have a gander at the other page butam confused by the different models sold by the same seller. Any ideas for something @US$25-30 per pair.

I have seen rainbows on this projector. But for me, they havnt bothered me. I was expecting it to completely ruin the dark images.

The projector is very bright and you can see rainbows easily. Add a ND2 filter and you can cut the rainbows by half at least.

I only noticed the rainbow once in a while and they only appear in different parts of a scene, Not consistent is what I meant. Lasting < a second.

Been around DLP projectors for almost 18 years and have never seen rainbows on screen. And I have never tried to.

I only saw them three months in, because I didn't use the torch mode (dynamic?). If you use User 1 or Cinema they totally disappear. Mess around, trust me, you can get them out (even on white backgrounds with black text or vice versa). I don't like wavy text b/c I use it as my primary monitor at home, but with the right settings the leprechaun monster takes a dirt nap.

Just to clarify, eco mode is the "lowest" setting for the lamp. From what I've read Smart Eco is more like a dynamic iris - bright scenes are still full power, but the light output is decreased in dark scenes. It should give you the best contrast ratio. The measurements that were posted a few posts back would seem to indicate this.

According to Benq once would get the longest lamp life using Smart Eco.
See Trusted Reviews info on it.

Smart-Eco is designed to save up 70% power consumption but it appears it is a semi-bogus specification because it's likely based against Normal lamp and as you can see from the reads I posted Eco has better black level and never does get as bright which could, on average, mean less power (vs smart-eco).

I think the only time Smart-Eco comes into play from a lamp life stand point is when there is no image it blanks out (Eco blank) and reduces power to the lamp. Anyone with a Kill-A-Watt can test this, see if eco draws less power than smart-eco while viewing the same mixed content, full field black and full field white.

Honestly I think the constant fluctuations of Smart-Eco will only serve to decrease lamp life as it constantly changes the lamps ARC. I for one can see the fluctuations of smart-eco but YMMV.

I am confused DaGamePimp if you're in favour of Smart Eco of reduced power consumption or normal.

When I view a pure White image I see a kind of water flow type fluctuation in the bottom right of the screen.

Smart-Eco will yield the best contrast and, according to my reads, the brightest image (which seems odd versus Normal but that's what the light meter shows on full field white).

If you are not bothered by the lamp fluctuations (pumping) then Smart-Eco will likely give you the more engaging image (and no reason to use Normal).

Eco has better black level and it is more obvious with mixed content than it is with full field black (at least to my eyes).

* Also consider that when in a non-ideal light colored room the more light you throw the more will bounce back at the screen causing 'wash-out'.

Anomalies like the one you mention can be heat related but difficult to say without seeing it in person.

What you say makes sense. It would be interesting to see what "A Kill-A-Watt" test shows.

The only way to update the firmware is to send the unit in to Benq. I know this is crazy but that is the way they do it.

Not true, a few pages back someone posted up the tools and how to update the firmware if I'm not mistaken.

It is not. You can install the firmware yourself. Read my post http://www.avsforum.com/t/1435626/benq-w1070-dlp-full-hd-3d-ready-with-lens-shift-for-1000/3180#post_23074743

Thanks Captain SHOK for doing the legwork and finding the post.

There is so much info in the 114 pages of posts we almost need some sort of Wiki page with notable info that can be updated.

Anyone want to nominate themselves? LOL
