I received a W9000 today and fired it up under my Samsung 710. My room is a cave and the screen is a 110" Carada BW.
First, the throw calculator on PC seems pretty close. The lense is about 159" (give or take an inch) to the screen and the height of the image ranges from 44 1/4" to 50 3/4", again, give or take a little.
The IRIS has 38 steps.
The pixels are SQUARE.
It is quiet, almost silent. The Samsung 710 is louder.
It seemed a little brighter than my Samsung (which has about 100 hrs on it).
I did a quick basic calibration with the get grey dvd and then flipped back and forth between the 2. I had a buddy over as well for a 2nd opinion.
There is very little difference in visible resolution from 12' back.
The Samsung appeared to have a sharper picture. This was visible on HD as well as putting up the on screen menu from my receiver. The W9 didn't look bad, but switching between the 2, it was obviously not as sharp. The letters for instance weren't as defined. Focus had no effect on this, we double checked. It was focused as sharp as possible.
I've noticed similiar traits between the different 720p chips, where the smaller chips don't appear as sharp and detailed to me. I'm assuming this may also apply to the different 1080p chips.
Nothing really stood out as an improvement over the Samsung in both our opinions. I wouldn't call it an upgrade, more of a sideways move in this case. The W9 could use some more calibration and I haven't played with the different iris settings so please take that into consideration.
