I have been pretty happy with my HD4000u but am looking to replace with a similar 1080p DLP.


I have been looking at the new crop of $1k 1080P's which range from 1500 to 1800 ANSI lumen's and I am finding some sort of ambiguity using Projector Centrals Calculator making it hard to compare to my HD4000.


Mits HD4000u is a 720p, 2000 ANSI lumen's

Optima HD806 is 1080P 2000 ANSI lumen's

Optima HD200x is 1080P 1500 ANSI lumen's


I have a 80in. diagonal screen in a semi light controlled room so brightness is important.


Using the calculator I get these values:


Mits HD4000u = 96 fl. at the screen


Optima HD806 = 50 fl. at the screen


Optima HD200x = 37 fl. at the screen


Is there a problem with the calculator or has something change in the ratings?? I know contrast numbers have switched from "full on" to ANSI but the stated lumens are all ANSI.


And yes I realize these numbers are approximate but has been useful to compare.


Anyone know whats up??

I finally found the problem; 4000u comes up with Data/Text selected for Primary Use.


The other two were set for Video/Movies.


For some reason I did not catch it
