Well they're both valuable measurements, but neither tell the whole story (eg ANSI uses 50% APL, while most video is closer to 20% APL) I think it's in the "New method for contrast measurement" thread that there's an interesting theory/observation/rule-of-thumb was posted. I think it's based off the theoretical model of the PJ/Room. That being that the "factor of 9". That On/Off contrast being 9x ANSI is sort of a threshold, where if the ratio is < 9, On/Off contrast is the limiting factor, and if the ratio is > 9, ANSI is.
That seems to illustrate, or explain the problems with current DI systems, sure they can hit 5000:1 contrast, but with the limited ANSI (~200-300:1) it doesn't do them any good.
Conversely, with my PJ and it's ~560:1 ANSI and ~1600:1 On/Off(as measured by Jason Turk), the On/Off is holding it back.
But anyway, that's way OT. I suppose one answer to my question is that since resolution isn't one of my complaints with my current PJ (black level/contrast is) a new 1080p, high-contrast PJ would help in that area. Then later as HD proliferates, I can move up to a better lens.
I've not followed that closely in the last year, so your post gives food for thought. Perhaps, though, the bottom will drop out on 720p DLP after CES. Then I jump.
Maybe you should look, I think the bottom already fell out of the 720p DLP market. The gap has really closed in the last six months.
