Alright, folks. I got the 2100 and a new Silver Ticket 92" grey 1.0 gain screen. Unfortunately the screen does skew my analysis a bit because I'm not comparing apples to apples in terms of the surface. The previous screen was just white blackout cloth stapled to a wooden frame I put together and a 73" borderless screen. Previous screen was about 9.5 feet away from my face, whereas the new one is about 10 feet away. Former projector was BenQ w600+ 720p DLP.
- Colours are superb. (I gave away part of my location with the spelling of 'colours'.)
- Brightness is a big step up from my previous projector, which I considered a good performer, even with ambient daylight.
- The colours and brightness come together, along with whites, to form a really clear picture; again, even with daylight. This was a 'must' for me as my screen's back is up against wall-to-wall windows. I'm sure this is some kind of grave sin in the videophile world, but allows a really cool layout and eliminates direct sunlight.
- The blacks and contrast are also a step up from the W600+. This shouldn't be a surprise to anyone but did put me at ease moving from DLP to LCD. Don't expect plasma or OLED-level blacks. But they're definitely sufficient for my needs, and even in the 'bright cinema' mode I found them sufficient during the day. During the day, with all my light, the blacks did wash out a little. But somehow the image retained enough clarity (the contrast?) that I could see details clearly. (Is this the auto-iris in action?)
- The jump in resolution from 720p to 1080p is nice, even with a 19" jump in diagonal screen size.
- The knobs for adjusting zoom and focus, as well as veritcal and horizontal keystone adjustments, made setting this up quite easy.
- I am 'the princess and the pea' when it comes to judder or choppy movement. Motion and camera panning feels nice and smooth on this projector, and it felt janky to me on the 2040. I assume they made some improvements in processing. I don't have frame interpolation on, or at least it's grey in my options. (Anyone know how to change that? Is it off because I'm viewing everything through PC HDMI input?)
- The image looks very sleek in general and I'm regularly feeling impressed by it.
- I'm noticing a lot of large, messy, pixel-like "noise" in streaming video through YouTube on HD sources that looked smoother on my 720p 73" screen half a foot closer to my face. I'm assuming this is due to the scale of the screen now which makes these streaming artifacts more obvious. Standing another 5 feet back the image does look a lot more polished (and for that matter, sharper; but that's peripheral to this issue). I'll try some BluRay video and get back to you on whether this persists in my current setup. I really do believe it's the source rather than the projector.
- My screen's fault: I see a greasy-looking texture/grain in the background, primarily in lighter scenes, which is a bit distracting. At night I actually go into 'natural' colour mode and turn the brightness down to 25, which cuts down on this significantly. Still, I'm a little disappointed (again, with the screen) versus my blackout cloth screen. Though the blackout cloth did have a bit of texture of its own. I think this is generally a step up, but not as big of one as I'd expected and far from perfect.
- Fan noise is slightly higher than what I'm used to, but I'll no doubt get used to it.
Hope this helps. I am feeling very satisfied overall, and am picky when it comes to this stuff. I am not at all wishing I held out for the 2150 or spent an extra $300 CAD (location fully revealed) to get the hypothetical increase in contrast.
