My thinking is to get the BenQ and use it in 16/9 only while saving up ASAP for the great Sony. Alternatively, I could spend about 2K on the Sony HW40 and do a little longer with it if that is suitable for 2.35/1. The house is for the weekends/holydays only during the next few years until it's completely finished, BTW.

One more question: the projector will mounted against the ceiling. I reccon it's necessary to use a mount and upside-down?
I was hoping to make a U-shaped shelve against the ceiling and put it on the shelve, upside-up. That's no go, right?
If, for whatever reason you got a scope screen, then you should be looking at the Panasonic AE8000 which has the zoom range, and a motorized zoom feature to deal with the two different image sizes you will need to deal with.

No chance I would go with the W1070 and a scope screen. You didn't buy a 2.35 projector, so using a 2.35 screen always requires some extra thought and effort and a serious case of 'does this make sense?' before buying.

You are probably right. The Panasonic PT-AT6000E as it's called in EU can be had for €1,500 these days. Lens memory is definitely nice to have. It's the main reason why I would not consider the Sony VW350.

You can set the W1070 up for a 2.35 screen in two ways:

1) Slide an anamorphic lens in front to expand the 112" 16:9 image to the 142" 2.35 image the same height. Anamorphic lenses are expensive but can be re-used with many different projectors. You will have more resolution and more light on the screen that the "zoom" method below, but the extra resolution will be "created" by the W1070 scaling engine. You can also choose to build your own anamorphic lens for under $100 but it will not be as good as a professional lens. Is it good enough to suit you at least temporarily ? Up to you.

2) The "zoom" method. Build a mount for the W1070 that allows the entire projector to be rotated around pivot points such that it can be "forward" with a 12' throw and lens 12" down from the ceiling but can be rotated down, then "back", and then up so it is at 13' throw and 2" down from the ceiling (essentially flush to ceiling in the "back" position). Then just use the zoom lens on the projector to fill the screen side to side and let the "black bars" top and bottom spill above and below the screen. The actual image resolution is only 820x1920 but it is all "real" resolution with no scaling, and you only get 75% of the light from the projector because the "black bars" still exist above and below the screen and contribute no light to the actual movie image. The resolution and light loss is true no matter what 16:9 native projector you are talking about.

Either method is more "trouble" and more "manual" that the Panasonic's lens memory. And the Panny has slightly better dark detail. But it also lacks the brightness of the W1070, the gaming speed of the W1070 if that is of interest, and it shows screendoor effect compared to the W1070. If 3D movies in 2.35 are desired, the Panny really is not bright enough for your screen size. The Panny is also $800 more than the W1070.

As to mounting, the W1070 must be upside down if setting up high. It can be mounted to the underside of something like a shelf or something like this:

and then set up on a shelf if you don't want or can't use a traditional ceiling mount.

Okay, thanks. Let me think about it.

There's no substitute for cubic inches.

Hello everyone


Can someone knowledgeable or who has previously experienced similar problem, please help diagnose the issue I'm having with my beloved Benq 1070?


My W1070 was functioning fine since installing it last August, but over the last few weeks, something is not right. After about 20 minutes of operation, faces on the screen take on overly saturated hues and tones, objects in background develop concentric/oval halos, accompanied by some flickering. It becomes quite unwatchable after a few more minutes. The projector sounds normal while all this is going on; I can hear the fan humming normally (no alarming changes in frequency), there is no red or blinking light that comes on. But the picture distortion I described keeps getting worse.

After hitting the stop button, I can hear a high pitched whine for a while, and the picture flickers quite a bit before settling down gradually.

If I shut down the projector and let it cool down for a few hours, it works fine the next time it is turned on...for 20 minutes or so...and things start to go downhill again.

I have attached a picture depicting some of the symptoms described above.

I bought this unit directly from Benq barely a year ago, the lamp has registered only about 350 hours. It came with firmware 1.08.


Any help/guidance is greatly appreciated.
