If another dedicated thead exists, I couldn't find it.
As far as I've observed and read, the DX605 is a rebadged (for TigerDirect, if not others) EP719. It's been compared favorably to the Sharp XR-10X, I'll list the specs below.
DLP ('Dark Chip' for better blacks)
2000 lumens (1750 in economy mode)
2000 hours lamp (3000 in eco mode)
2500:1 Contrast Ratio
4.4lbs (2kg) - some say build quality is inferior to the XR10X, but it's half the weight so...
Color wheel speed is not precisely known. Broad speculation suggests 2x, but one review (projectors411) says it's 4x speed. 4 segments (RGB+W (clear)).
Throw is a little on the longer side (check projector central for details)
All the standard inputs for a business projector + DVI (HDCP enabled) - VGA has both input and output.
Comes with a small, reportedly good carrying case.
Ringing up well under $1k, it's a strong contender in the Budget/Light Canon group.
The consensus with these 2k lumen DLPs is that they benefit from a gray wall/ND filter/negative gain screen. The 719 supports 'window mode' which allows for a fixed 16:9 screen with 4:3 material inside the 16:9 frame with vertical bars on the sides. This is popular since much of/most 4:3 content is SD television and no one wants to watch that at 100". It's has something like Sharp's 'image shift' which enables you to choose which portion of the 4:3 image you want to move the 16:9 frame up or down to. This amounts to 1-side masking, instead of top and bottom.
I ordered mine some time back but I won't get to test it for another month or so - review forthcoming but be patient with me.
The two reports from people who've seen both the XR10X and the 719 give the 719 a slight edge, if any.
I'd LOVE to hear from other 719 owners. Problems, fixes, screen suggestions, comparisons etc. I'd also like to know if the clear segment (white) can be disabled through some setting, like it can on the XR10X.
