BenQ W1070 : DLP Full HD, 3D Ready with lens-shift for 1000$ - Page 243

post #7261 of 8480
My (june bought) w1070 was replaced by one manufacturer in sept 2012. Should I be worried then about this?

Thanks for a quick review!! Yea, no kidding! I though Optoma would be on par or better in sharpness (at least according to some of the reviews I read on the net). I would like to get a "high-end" PJ, but I don't want to drop more than $1K on the whole system.

Thank lapino, but you helped me make a decision: BenQ W1070 it is smile.gif

The consensus seemed to be that long-term, SmartEco was therefore best avoided, though at least one person opened up their projector and added additional lubricant to their fan bearings successfully.

It seems unlikely Benq could fix this with a software update, since running the fan at high Normal levels would decrease the reduced fan noise that is a key benefit of SmartEco. Benq could always spec a better fan, but that seems more likely with the replacement for the W1070.

I think they fixed this issue.  I have 1.08 firmware and in Cinema mode using SmartEco the fan runs at the same or even slightly higher speed as Normal lamp mode.  That is with this forum on the screen, so displaying basically 3/5 of the screen white.

 

So yes decreased fan noise is not a benefit of SmartEco.  It should really just be called Dynamic lamp mode.  Fan speed actually seems to be somewhat dynamic as well.  Put a dark screen up and it slows down, but never gets even close to as slow as when on Eco.

Interesting. Will be interesting to see what else 1.08 fixes. This does suggest Benq is paying attention when issues crop up, which is reassuring.

Why? You're doing yourself a disservice. This is the same as RBE. Ignorance is a blessing.

You WILL find uniformity issue if you measure it. In fact, not a single projector, even a $20k one, can be absolute uniform.

Once you measure your 1070, you will feel how crap it is, for the rest of your life.
post #7267 of 8480
Well alright then lol. I won't ruin my perspective of how nice this projector is by measuring it. Its my first theater room and I see no rainbow effect either. I run only in eco because I'm afraid of messing the bearings up with smart eco. Bit I'm in a small 10x14 bat cave so eco is just fine plus the lamp will last longer

Technically a longer lamp life is claimed by Benq for SmartEco than Eco. Some folks have theorized that the fluctuating lamp levels may increase longevity.

Eco puts out a lot of light, I imagine it's a more pleasant viewing experience for you in a bat cave, at least for 2D. I loved the brightness of SmartEco when I first got my projector, but found it became fatiguing to my eyes over time.

First of all thank you for sharing the firmware and tools

 

I am unable to update firmware i checked the forum but couldn't find any helping post. I am using win8 64 ( although i did everything as said in the document/manual) when i click download firmware button in dlp, it freezes for couple of second and gives a timout error:

 

          USB Errors: Error: USB request failed - The wait operation timed out.

 

I am sure that pj is in download mode (it has red light) and Windows doesn't give an unrecognized device error or unknown device. When i unplug usb cable from pc, flash loader in dlp says it couldn't detect pj but while plugged it doesn't gives such error. So i am guessing it sees the pj. I tried different usb ports but that didnt help and saidly i dont have any other operating system i can try. I am curious wheter anyone else had similar problem or can suggest something. Since my pj has 1.05 i cant watch 1080p sbs i really need to update it:((

 

 

ps: sorry for my english :(

I would print out the instructions and start again. You must be sure that you put the flash parmariter file in the proper folder. You must also make sure that the you set the output to USB.
post #7271 of 8480

Sadly but i have already done those :( and i triple checked firmware txt file :( also i found debug mode on dlp and it says :

Btw is it normal for flash loader to say vid: 0x451 and pid 0x4421 in status (just below download firmware button in flash loader in dlp)

post #7272 of 8480

Just got my 1070 today and got it mostly setup.  It looks great, but I can't the thing aligned properly.  My previous projectors all had both a keystone and trapezoid adjustment, but this projector only seems to have vertical adjustment with digital keystone and vertical lens shift.  My picture is slightly pinched on the right side.  Is there any way for me to correct this short of moving the projector itself (which isn't possible due to the location it is mounted)?

post #7273 of 8480
What I've notice -just a perception, I couldn't measure it- is that with 1.08 the fan noise when Brilliant Colour is activated is the same than with the feature non-activated. On 1.06/1.07 version the fan noise with BC activated was higher (in ECO mode) than with it non-activated.

About greenish I didn't have the oportunity to take measurements with 1.06/1.07 but with 1.08 i only had to reduce green gain a couple of points to have a perfect grayscale.

Other point that I'm not sure is about default configuration. I see that with 1.08 the default gamma value is 2.4 and i think that with 1.06/1.07 the default value was 2.2, could anyone confirm?

Thanks. Regards

This could be reduced turning off Brilliant Color and using Smart Eco lamp mode. I have not tested this new firmware with Brilliant Color and Normal Lamp mode since I have my unit calibrated with Brilliant Color off.
I would guess that with these changes fixing the out of box green and noise would make the unit even more accurate out of the box. Hope someone can make a comparison.

I think you are correct that with 1.06/1.07 the gamma value was 2.4 in certain modes. Many calibrators and filmmakers prefer 2.4 as the standard rather than 2.2. I decided to use the ISF mode for calibration and save settings. To get into ISF mode up down, up down, left right.

Wait I thought it was up, up, down, down, left, right, left, right, B, A?

Sorry, my error. I corrected it. Early in the morning on the east coast but no excuse.
post #7277 of 8480
Thanks for your comments.

Regarding calibration the measures I took in cinema or user mode show that with gamma set to 2.2 the mean value is closer to 2.1 than to 2.25, and with 2.4 the mean value is closer to 2.3 or even lower, is this behavior normal for this projector?

I will try to calibrate using ISF.

Thanks!!

I've see the same thing with my projector as well. I actually use 2.5 gamma, but I've seen 2.4 give anywhere from 2.2 to 2.35 or so on my projector.

I admit, I didn't read all 240+ pages, but are there "preferred" settings for this projector?

I have this same fan behavior with firmware 1.06. Has nothing to do with 1.08

same here; right now I'm seeing $949 on Amazon; don't know if it's been lower than that or not, as I haven't been looking that long. Sometimes there are sales as the superbowl approaches; don't know if I can wait that long or not!

Just for anyone to want to update the proyector, the drivers wont work in windows 8.1 (maybe win8 too) tried yesterday to update my projector on my desktop and my laptop, both with windows 8.1, and it didnt found drivers for the projector. Tried on an ancient PC with windows XP, and worked at the first time.
post #7284 of 8480

I didn't found on the search, so here it goes:
How is better: projector closer to the screen with maximum zoom, or projector far from the screen, with less zoom?
Is there any difference in the picture quality between the options?

 

Other thing is that I've read that the color wheel only runs at 6x if the image source is setted to 50hz. Is it true?

Thanks!

I was going to ask the same question as PC Parmera.

I did read that it's ideal to place the projector behind the seat (at least one foot) and to sit at least 1.5 times (ideally 2x) the width of the screen. So in case of 125" diag screen (109" width), it means I should be sitting approx 13.6' from the screen. In order to achieve this (i.e.; placing the projector 13-14'), the zoom has to be maxed out at 1.3x. So same question as PC -- will the quality of the picture suffer?

Are you guys saying that setting it to gamma 2.4 is better? I did notice that black levels are better at 2.4

Technically, black level will be better and better as you increase gamma, but you'll also get black crush and a very dark picture if you go too high. But, gamma at 2.4 will give an actual gamma closest to 2.22 on this projector. I chose to use 2.5 because I can get a little bit of extra "blackness" without sacrificing my picture in my room which is totally blacked out; this might not be ideal if you have a room with some ambient light or brighter colored paint.

I updated my PJ to 1.08 with no problems.

My laptop has Windows 8.1, 64 bit. No issues. Not sure what would have caused your problems but I don't think Windows 8.1 is to blame.

Personally I don't think you should worry about this too much. My screen is 120" and I sit about 8' away from it. The projector sits behind my head slightly. I prefer sitting closer to the screen because it takes up more of my viewspace. Instead of simply watching a film you experience a film. I can understand why some people prefer to sit a little farther away because with a screen taking up that much of your viewspace you can miss things on the periphery, but I prefer the immersive experience. I think this really comes down to personal preference and not any technical requirements. I can tell you with this setup I cannot see individual pixels unless I lean forward and squint at the screen. So that's my 2 cents, I like having the screen take up the whole wall, try it out and see what you prefer and don't worry too much about what others say about what is "ideal".

As I wrote in another post...

Pros of mounting closer to the screen:
- Some have observed that this model seems to hold better focus across the full screen when mounted closer
- Brighter (may be a negative, but certainly helpful for 3D)
- Farther from your head (less fan noise)

Pros of mounting farther from the screen:
- Out of your peripheral vision
- Less bright (may be positive for 2D viewing)
- Higher contrast (basically as a function of lesser brightness)
- In theory, should be sharper due to only using best part of lens, though in practice this doesn't seem to be the case, as noted above
