BenQ W1070 : DLP Full HD, 3D Ready with lens-shift for 1000$ - Page 58

Easy way to center your projector lens on ceiling relative to the screen:

1. Determine desired projection distance of your lens from screen using projector calculator.
2. Locate approximate mounting point on ceiling using projection distance measured from top center of your screen. You can use sidewall measurements to get an approximate screen center offset at the projection distance and mark on ceiling as the projection/lens point using pencil or tape. This is an approximate lens location since sidewalls may not be perpendicular to the screen wall.
3. Now use a tape measure and measure from top left corner of screen to marked projection point. Record this distance, while using the extended tape as a string radius to generate a circular arc while holding a pencil to scribe an arc of about 4 inches around the projection point.
4. Now place the tape at top right corner of screen and scribe another arc using the distance recorded in step 3. Where the arcs intersect is a point perpendicular to the screen and at the screen midway point. Just make sure that the arc intersection point is inside the lens focus distance for the projector.
5. If the projector lens is offset from the ceiling mount base, then offset the ceiling mount base by that offset distance to get the projector lens at the intersection of the two arcs.

Good luck!

I tried a 3d SBS bluray rip tonight just to try out of curiosity (I buy all my Blurays, don't worry), and to get 1080p / SBS mkvs to play I had to run TMT 5 + set my videocard to 1080i output. Then the projector's 3D button worked and allowed me to set side-by-side. Jeez, it would be nice if their next one could..you know...auto detect side by side or frame packed or top down 3D content. I'm crossing my fingers that a firmware update might be able to do that. But I didn't like the quality of 1080i SBS rips compared to 24hz frame packed. Just looked choppy and not as good. And I'm a huge fan of smooth video.

You're welcome, man this PJ is a real trooper. It only shut down from overheating once on me, and that was my fault for accidentally blocking one of the exhaust vents. But it handled it like a champ and waited till it was properly cool before even trying to turn back on. I figure if I got 400 hours in two months of super heavy + nonstop holiday usage, and 6000 hours is the lamp life of Smart Eco, I can assume that 30 months is a good time to buy another 200 dollar replacement bulb. This is the little projector that could. I'm glad about the performance, but REALLY glad about the reliability. I am using and abusing it daily and nightly. Can't wait to see what it looks like when I set it up with a proper screen and wide angle lens and get it calibrated and all that good stuff.

A projector that can do all this has been the dream of many in this forum for years since 3D came out (especially the sub 1.5k budget guys).
Truly an amazing projector at a great price...

Hey JoeBoy... you have no idea what a nightmare its been trying to get this aligned with the screen. I consider myself a decent DIY'er but man apparently Im not cut out for doing a PJ/Screen setup. Im at a point where I think Im ready to give up. I have a projector mount that allows plenty of space for the projector to move vertically so thats not the issue at all. I have measured, and then measured some more and nothing seems to work. My PJ mount allows the PJ to rock forward and side to side, tried everything I could. Lasers, tape measures, meter sticks, plumbobs, etc. It just wont align with the screen. The projector is freaking A M A Z I N G (seriously)... BUT I just cant get it setup properly. Not sure how to fix that funky keystoning Im getting. I guess Im just an inept PJ/Screen installer.

I took a quick pic of my PJ mount for you, sorry about the bad picture...

Are you sure the screen is actually flat - i.e. that it's perfecly parallel to the projector lens (without any bending)? Because -- looking at the photo you posted -- from the way that the image is projected on the screen, it looks like the screen itself could be bending. Maybe the wall you placed it on is not flat? If so, that would explain why moving the projector isn't able to solve the problem...

Certainly worth looking into I suppose. I did check earlier and the screen (to me) appears flat. I guess I could move the screen around a little off the wall and see what happens to projected image tomorrow when I have some time. Thanks for the suggestion. Appreciate the post dzenc.

I would try to mount the projector on a small box near the floor temporarily for testing, get it level that way first and see if any adjustments make it correct with the screen, then try again on the ceiling after doing so. Also, you should be using a test pattern while doing the mounting, you need to be displaying a grid pattern or something similar on the projector so you can see the mis-alignment exactly in terms of a projected grid. You can use a pattern from the AVS Rec709 test disk or from the Benq service menu (it most likely has a grid, the w7000 does).

Do both those (floor + image of grid projection), and that should help you get out the unwanted variables in case you need to make screen adjustments. I always do both those steps before ceiling mounting, because if you can get the image correct from the floor onto the screen, then chances are you can also get it the same way from the ceiling.

Okay I will be doing those tomorrow then for sure. Thanks for the post coderguy. The BenQ does indeed have a test pattern grid in the menu. Will report back tomorrow how this goes. Really just want to get it all worked out and enjoy the projector!

This is the mount that worked for me. It has many adjustments and make things easier even though the projector does not have a lens shift. I have an 8' ceiling and mounted the projector about 9 feet from the screen for about a 90 inch pic.

Hi folks! I'm so confused. I hope you can help me? I've read this and other threads that says "Any DLP-Link glasses will work." But then I read that "only 144hz glasses work and not 120hz." I have a sony 3D blu-ray player that I will be hooking up to this projector. Which 3D glasses can/should I buy? I don't want to spend, hopefully, more than $50.00 a pair.

Thanks

I was just going to post this question. Since a bunch of us got the W1070 last week from VA and PP, what 3D glasses is everyone planning on getting ? BenQ, Sainsonic, TrueDepth, etc ?

So i got the PJ with firmware 1.02. Since we cannot update it, how can we go updating it? Bring it back to Benq? Seems like a hassle. Though i don't see any issues with my PJ.

I just had a very irritating chat with a BenQ rep. I am interested in the W1080ST so I've been following this thread since it and the W1070 are virtually the same except for the short throw lens on the ST. I asked the rep if the W1080ST would ship with all the firmware updates of the W1070 as there were a few bugs with it when it initally shipped. There reply was "this is a new model. There are no bugs". The rep then proceeded to tell me that I should read the specs and then I would see that the 1070 and 1080ST were completely different. As I paused a moment to gather my thoughts, I was disconnected from the chat.

Why do I get the feeling I know more about the products than the company rep?

Anyway, just venting...

I also have 102. I spoke to Benq several times and the only way to get the update at this point is to sent it back to Calif. It is a hassle and I do hope that they eventually change this. I have all the cables and equipment necessary to do it and I have done hundreds of firmware updates but they still will not let me do it. Regarding the differences in firmware. 103. Fixed a flicker issue some were having and 104 fixed a fan issue. I am going to wait a few months to see if any other issues develop before sending it in. I suggest that others do the same. I should also point out that the problems mentioned were not on all units.

You must get 144KZ glasses. SanSonic are the least expensive at about $25 each on Ebay. Make sure you get them from a US suppliers stock.

It is probably the same mount though mine is black and cost a few dollars less.

TrueDepth 3D DLP Link glasses and problems:
I reported earlier after a brief viewing session that these glasses worked well using a 3D BluRay movie. After more extensive testing, I discovered some occasional flickering instabilities, some lens blacking out, and some synching problems as I changed Direct TV 3D channels. In addition, I experienced headaches, and depth perception problems that are difficult to explain, but may make the movie unwatchable. I believe the engineers need some more time with their glasses.

I used earlier version True Depth 3D glasses with my Optoma 3300 without fail...really excellent. And their customer support is excellent. I am sure they will get these problems fixed, but must return mine at the present.

Thanks! Just ordered a pair

Here's the ebay link: $24.99 includes shipping here in US. http://www.ebay.com/itm/SainSonic-144Hz-for-BenQ-3D-DLP-Link-Ready-Projector-IR-Active-Shutter-Glasses-/251220658740?pt=US_Video_Glasses&hash=item3a7deb0a34

Anyone tried these by Okeba, or heard if they are any good?

User review states that they work with the Benq w1070

I have just received my second projector from Future Shop. This one has the same problem as the first one. Can anybody else confirm this: when I use zoom to fill the screen perfectly, and then I begin focusing, does the zoom move in and out while focusing?

In other words... When you are moving the focus wheel, does the projected image size stay the same, or does it move in and out a few inches? I have never seen this in any other pj before.

I have tried these and while they list them as 120kz they are actually 144kz and work ok. I think the SanSonic are a little more comfortable. I am waiting for the Advance 3 DLP 144 glasses coming out soon. I tried the 120KZ Advanced and they would not work but they seem really well made and were very comfortable. I was told that the 144k versions will be available in about a month for about $50.

I can confirm this does indeed happen. Seems to be a normal and small annoyance with this PJ I guess in the grand scheme of things.

I can confirm the same.

Yeah mine does that too. I don't see the big deal. I just zoomed a little and focused a little until I got the size dialed in while keeping the focus relatively close the entire time. Took like one extra minute. I can understand it seeming a little weird but I didn't even remember I had to do it that way until people brought it up. Once its dialed in you shouldn't have to mess with it much.

Mine seems fine. If, however, I zoom to the black mask at the L. and R. side of the screen and the image is soft - and then I go to make it sharper by focusing, the image will "shrink" slightly. This is the same effect ("breathing") I've seen with a lot of projector optics - and older film projectors too. I don't have any issue that relates to how the zoom works with focus.

Hope this helps.

Thanks for checking guys. I called Benq before I ordered a 2nd one, and the guy on the phone told me that it shouldn't be doing that. That was the reason i did an exchange. Oh well...and I still got a 1.02 Nov build. Was hoping for a newer one. Also, my box seemed like it has seen better days, a few minor bangs here and there, and scratches etc...kind of weird..looked like an old box sitting in a garage for like 20 years.

Hi, everyone --

New forum member here. I just received my W1070 today (bought from VA), and after testing was disturbed to find that the fan didn't run more than about 5 seconds after I shut it down. It's supposed to run for 2 minutes, right? I ran it through a couple of couple of on/off cycles to check -- have I now damaged my projector? I'm on firmware version 1.03. Is this the fan issue that 1.04 fixes? Should I not use my projector until it's fixed? I'm more than a little annoyed by this -- the projector was shipped directly from BenQ, so I naturally assumed the firmware would be up to date, and I'm now faced with having to turn around and ship it right back without even getting to use it, and wait potentially weeks for the update.
