I zoom all the way out to 230cm wide for scope films, and usually around 180cm wide for 16x9. This is pretty much constant height.
The unit I bought had just under 500 hours on the lamp, which was really a good thing as I didn't need to wait for the lamp to settle down.
Firmware is the latest (1.01)
Settings (Economy lamp mode):
Clarity Control: All three set to 0
Dynamic Black: On
Brilliant Color: Off
Black Level: 0 IRE
* The black level is slightly deeper than the W5000. Turning on and tweaking the DI improves it a little further still. More experimenting to do here.
As the peak white level is a good deal brighter than the W5000, you get a noticeable boost in contrast.
This concurs with Spexman's findings here.
* The DI ( Dynamic Black ) is a huge step up from the W5000.
It's very quick to respond, and the best thing is that you can tweak it.
As others have noted, setting +66 for Aperture Max eliminates clipping on peak whites, along with associated colour fluctuations.
This was often pretty horrible on the W5000. Here it's terrific.
I'm a bit confused about a few things though...
?* DB Aperture Position is a wierd one. This effectively acts as a global iris.
However, on a few occasions the iris won't budge until you hold the button down for a few seconds. (You'll hear it trying, though)
One other time, lowering the number actually brightened the picture! Hmmm...
?* Anyone know what DB Strength does?
I remember reading somewhere that changing the default of +2 to +1 or +3 actually deactivates it. That seems weird.
?* DB Aperture Min obviously sets the lowest limit for the black level.
Any reason why 11 or 13 is recommended? I tried dropping it all the way down to 1 for deeper black level, and didn't observe any crushing of shadow detail.
That said, I still preferred the extra punch up around 10, although for some films it's a nice option to have.
The settings I'm very happy with for now are...
DB Aperture Position: Around +46 (although setting this lower/darker can help some material)
DB Aperture Max: +66
DB Aperture Min: From +1 to +13 (around 10 seems to be the sweet spot)
DB Strength: +2
With these settings, the visibility of the DI is almost completely invisible, no crushed shadows, clipped highlights or wonky coloured peak whites.
* Sharpness! Despite using a smaller chip than the W5000, it's every bit as sharp. The extra brightness & contrast pushes this a good notch further.
It's slightly sharper (and punchier) than the far more expensive Optoma HD8600 / HD87, and miles ahead of LCOS projectors like the JVCs.
Gotta love those Benq optics...
* Rainbows... No problem at all.
I left CCA alone for now, and just settled on this...
