If you are that handy, you won't lose anything by drilling on your exsisting mount. However, make sure the center of that mount will line up at the center of that triangle, otherwise, the unit will be off balance, n you want to avoid using the keystone if possible.

I used a similar one as yours. But one cannot blame somebody who try to save a few bucks.

Finally got my HW15. Upgrading from a Sony HS10, its pretty damned impressive.
Huge improvement in blacks, detail, colours, and noise level.

I'm playing with a HW15 too. Is there any advantage to going into the service menu for various adjustments? Perhaps tweaking the iris, etc?

I am using the Cinema Mode, low lamp, Auto Iris 1 n then use a Bluray calibration disc 'HiVi Cast'(from Japan) to dial in Contrast, Brightness, Hue, Color, Color Temp. n Sharpness.

The picture is Magnificent !!!!!!!!!!!!!!!!

Are you using Gamma 4? I only have a few hours on the lamp and outside of Brightness and Contrast I have been using projectorreviews.com settings.

Yes, Gamma 4 n Color mode is Wide. However, on Contrast, Brightness, Hue n color etc., you have to calibrate yourself, since Projectorreviews has different screen n room setting than yours. But choosing Cinema mode is a good place to start to achieve 6500K color temp.

I watched my first movie tonight with the HW15 and I can't say how much I love its lack of noise. Coming from a noisy DLP it was unbelievable. Even at low levels the audio was extremely directional and sounded so peaceful without the underlining color wheel and whatnot whirling away. The lack of the noise distraction made it much easier to get taken away.

Since I haven't seen the film before I can't say how it compares to other projectors but I will say the skin tones were terrific. Very little noise (lack of pixel structure) and the color had very nice variations.

I'm trying out the HW15 right after trying two Epson's 8500UBs. The first had massive convergence issues with the second being better (not as good as the HW15 out of the box) but it had a color uniformity issue. The top two-thirds of the image was shifted towards red and the bottom third blue. I retuned both and currently I haven't found a single reason to return the Sony.

Besides the QC problem on Epson, how do you compare their picture quality ?

Interesting question...

My receiver has dual HDMI output so I can output the image at the same time to two projectors. By holding up a black sheet of cardboard over one of the projector's lens I can instantly switch back and forth. I think I noticed more differences when I wasn't comparing them instantly. Neither projector was calibrated to any degree. I basically used projectorreviews.com settings and did a little tweaking from there.

If I had to summarize their difference in one sentence I would say the Epson has a little more punch and or perceived sharpness and the Sony is a little smoother. They both have identical detail and even flipping back and forth any differences were very minor. I only viewed a half dozen or so scenes and didn't noticed a lot of black level difference.

All and all I didn't spend enough time to really come to up with any real conclusions. Once I saw the color uniformity issue with the Epson I know I couldn't live with it and I wasn't going to try a third unit. The differences I saw flipping back and forth were very minor... and one could make a case for either. I'd say the Epson is halfway towards DLP (video look) and the Sony is pure SXRD (film like).

I think a lot of this difference is the result of the LCD's greater pixel structure as in my opinion it gives the image a perceived sharpness. Although at the same time it adds a little noise to the image.

Has anyone tweaked the iris settings in the service menu? Perhaps to create a lower black level? I have seen such with the older Sony models and I'm wondering how close this model is related to them.

Thanks for your comment. However, I am not as lucky as you are to compare them side by side, but at 2 seperate location. My memory was that Epson has a deeper black than 15 but deep to a point I feel it was too heavy(dealer said the unit was calibrated), unlike the JVC 550 that has deep black but light n transparent.

That's how I learnt that one cannot judge the picture quality of an unit base on Black level alone. I agreed with you the Sony HW15 is much more natural n Film like n more even throughout the whole color spectrum.

I think shadow detail is average at best with the Epson which might explain what you saw. I tend to look for the projector with the least amount of issues based on what's important to me. Like with the Epson the lack of color uniformity far exceeded its lower black level.

Testing a VPL-HW15 I noticed that the right side of the projected image (shelf mount) pulses whenever the image is frozen. I believe it does it as well when the image isn't frozen but it's harder to see. The left side and center image is stable and doesn't pulse at all. Pulsing appears to be half a pixel or less but very noticeable and it appears to be on the entire right side.

Anyone else see this? I tried disabling the auto iris and the pulsing was still there and it doesn't appear to be a light difference rather the image itself appears to be moving (again only of the right side).

Just wondering if the unit is defective or perhaps it's normal. I can't believe it is... but one never knows.

Update: I placed a piece of paper in front of the screen and the image pulsed on it too. So it's not the screen moving. Left and center is fine... right side pulses.

I've watched about 4 movies since installing this projector last week and have not witnessed this pulsing behavior. I've definitely paused the movies.

What do you mean by picture frozen ? Do you mean you pause the picture on your Bluray player ?

I don't have your problem but 2 different ones as below from the first day I had this unit 1 month ago :

1) 6 out of 10 times I cannot turn on my unit with the remote. Once I turn it on with the button on the side panel of the unit, the remote just function fine. I have changed batteries as well as exchanging new remote with the dealer plus turining off all CEC control but the problem still exist.

2) I have to turn on my AV amp. before turning on the HW15, otherwise it will have a HDMI handshake problem n no picture.

Do any HW10 or 15 users have similar problem ?

I'm looking into the VPL-HW15, but I have a question for HW15 owners about lens shift.

Looking through Sony's manual, they make it really hard to figure out lens shift, with not only an obtuse formula, but the offset they use is a measurement from screen center not to the projector's lens center, but to the top of their own $800 mount. Grrr, not very useful. (I'm looking at the drawing and chart on pp 71-72 of the above linked manual. The formula "y (max) = 8.0942 (5/16) x SS + 268.5 (10 9/16)" makes no sense to me and I can't get a reasonable number from it, with SS = screen size in inches or mm.)

So in my HT, my ceiling flush mount typically puts the lens about 13-14" above the screen top, for a 100" screen. I think it looks like that will work with the HW15 but I'm not at all sure. Can anyone confirm that this is in the vertical lens shift range?

It might be the same but your link is for the HW10 not the HW15. Anyway with a 110" diagonal image I couldn't get away with the lens being 14 or so inches above the top of the image.

The specs state the image can be moved up or down 65% of the image height from the center of the image. Which means if your screen height is 54" you could shift the image up or down up to 35" above or below the center of the image. Which should be 35" - 27" (center of the image to the top/bottom of the image) = 8" above or below the image.

That looks real close to what I experienced. Here's a link to the HW15 manual...

Wow. Just spent an hour on the phone with Sony support, called or was referred to 3 different numbers, spoke to 6 people, the last of whom was a "product specialist". When I spoke to this last person and gave him the model number, he repeated it as if he'd never heard of such a thing. Ultimately, he ended up referring me to... the calculator at projectorcentral.com! Holy #@%!!! That's ridiculous, and gives me a big hesitation about Sony now.

But, I think I have this lens shift formula sort of figured out. Going back to pp 14-15 of the manual, it actually uses the lens center in the formula and gives a chart showing 31 7/8 for a 100" screen. Hopefully that's correct, but based on inconsistencies in the chart, I don't have really high confidence. Anyway, it looks like the formula breaks down as:

Y = vertical offset range
X = horizontal offset used (if any, 0 if not)
SS = screen size

(if screen size in inches)
Y = -1.463 * X + 5/16 * SS
(This gives me 31.25, which seems to make sense.)

(if screen size in mm)
Y = -1.463 * X + 8.0942 * SS
(This gives me 20559.26, which does NOT make sense.)

Can any owners chime in on the vertical lens shift range?

Thanks, Charles... looks like you posted while I was writing an update. BTW, the manual I downloaded was from the HW15 product page and is titled for the HW15 but you're right, it says HW10 internally. At any rate, looking quickly at your link, the numbers in the table are the same, as is the formula, so they don't appear to have changed any geometry between the HW10 and HW15.

The 65% figure is something I did see somewhere too, and came up with similar numbers. For a 100" screen, height = 49" so that works out to 31.85 which is almost exactly what I found in the chart and formula. But you reminded me that is actually from lens center to screen center, so it's only about 7-8" above the screen which won't work for me unless I suspend the projector by another 6-7". (If I had an 8' ceiling instead of 8.5', it would be very close to enough.) Bummer...

I can't speak for the HW15 as I haven't checked it out real close but with the other projectors (Epson and BenQ) I have been playing with you pay a dear price for using the lens shift. It really adds to the chromatic aberration. Often throwing a single pixel line into three pixels or so at the edges (perhaps two pixels wide further in towards the center). And looks to hurt the entire image to some degree.

That makes sense - I am a little familiar with CA from some amateur astronomy interest, and I never had experience with lens shift until recently but always wondered about that. I'll have to check some on my currently mounted W6000, which is near the max of its shift range. I've also got a Sony VPL-VW60 on hand for evaluation, and it seems to have a larger range than the HW15 but is also near the max (or slightly over, likely, as I had to tilt the mount down a little to hit the screen). Actually, the same tilt is in use for the W6000 even though its specs say it should be able to accommodate my 13" drop from lens center, so that makes me think maybe the HW15 might fit right in to the same geometry.

Seems a little odd to me that if I had a standard 8' ceiling, all of these projectors with no tilt would still be at the very max of their vertical lens shift range. I don't get why manufacturers seem to think that most people will shelf mount. (I am sure there are a bunch of folks out there with vaulted ceilings thinking that I'm a goofy ijit with that comment... )

I've also got a Sony VPL-VW60 on hand for evaluation, and it seems to have a larger range than the HW15 but is also near the max (or slightly over, likely, as I had to tilt the mount down a little to hit the screen). Actually, the same tilt is in use for the W6000 even though its specs say it should be able to accommodate my 13" drop from lens center, so that makes me think maybe the HW15 might fit right in to the same geometry.

Seems a little odd to me that if I had a standard 8' ceiling, all of these projectors with no tilt would still be at the very max of their vertical lens shift range. I don't get why manufacturers seem to think that most people will shelf mount. (I am sure there are a bunch of folks out there with vaulted ceilings thinking that I'm a goofy ijit with that comment... )


I am not certain, but I don't think anyone except "goofy" people hang out at AVS.


I am curious about your experience with the W6k and how it compares to the HW-15. I am interested in upgrading my InFocus 7210 (720p), but need to light a 150" 16x9 screen from ~19'.

There are just two theories for successfully quarreling with a woman -- neither one works!

Sony service people came to my place yesterday n the problem was solved.

Try to avoid using the HDMI CEC on/off control if you have different brand of equipment in your chain. Besides the HW15, I do have a Onkyo 805 n Pioneer 05 in the system. When the HDMI control is ON n turn off your projector, both the Onkyo n Pioneer will relate different command back to the Sony n cause the processor inside the HW15 to jam, before shuting themselves off.

Now I have that HDMI control in off position on all 3 equipment(not just the Sony), everything is back to normal. From this experience, I can conclude the HDMI technology is not perfect yet n it seems different makers have different protocol on how they want their gears talk to each other thru HDMI.

1) 6 out of 10 times I cannot turn on my unit with the remote. Once I turn it on with the button on the side panel of the unit, the remote just function fine. I have changed batteries as well as exchanging new remote with the dealer plus turining off all CEC control but the problem still exist.

2) I have to turn on my AV amp. before turning on the HW15, otherwise it will have a HDMI handshake problem n no picture.

Do any HW10 or 15 users have similar problem ?


Man see things as they were n say why. I dream of things that never were, n say why not ....... A Perfect PROJECTOR
