Just got our replacement W1070. Let the little lady decide to give the W1070 another shot or go with a W1080ST. She let BenQ do a new replacement for the W1070.
Took a few emails to get the RMA from BenQ. We had them ship a new one while we waited for the RMA — this was all through BenQ who matched VA price of $899 back when we originally purchased.
So. . . what's different?
- Packaging — this one was packed inside another box. Previous one was only in the W1070's box.
- no "smear" on the lens
- Seems brighter. . . noticeably so.
- default color settings are different — seem to look better at first glance
- Squaring it with the screen seemed much easier.
- cover over the lens shift screw clicks shut
- of course, don't have the issues that caused us to return the other one — fan bearing noise and half side of screen darker.
Firmware: both 1.04. . . bummer it isn't 1.05, but doesn't look like much changed there. Hopefully if I do ISF settings they will be remembered

This is one is a February build. Previous one was January.
Color Settings & Brightness
The old one color temperature settings:
100/100/100/256/253?/256
the new:
95/89/93/256/256/256
everything in color management is at 50
If you have played with these settings you know they will make the image darker when reduced below 100, but with the new settings the new projector is still noticeably brighter. If I change the new settings to what I had on the old projector it's very bright.
Remember, I'm using a temp white DIY 84" screen. So, it should be bright at that size.
Now cinema w/ 2.4 gamma is as bright as I had with 2.0 gamma and the old settings — cranking things up to my "brightest" settings that I had on the old projector gives me a very bright image.
Setting this projector up seemed much easier. The previous one was always a pain to get square with the screen. This one seemed very easy.
Fan noise. . . with high altitude off it's actually very quiet. We are right on the edge for having high altitude on.
Heat (environment temp ~65F)
With high altitude off it's blowing @ ~190F
Will have to measure it later for HA on
All in all seems better out of the box than the first. . .
Now time to run it for a while and see how it does. . . fingers crossed.
