Been looking to pick up a projector for watching DVD movies and stuff off the Tivo.

I actually have hooked up and used a friends Dell 2200MP and in a dark room it was quite enjoyable, although if you moved your head real fast white images would get a "rainbow effect" near them anyway below are 3 projectors one is Polysilicon and two are DLP (one being a Dell 2200MP) based on the features in the product litature why is the Boxlight Premiere almost 10 times the price, when the two DLP (at least to my amatuer eyes) seem to be identical (is there some spec I'm not reading as being wildly different)

The Premiere is also more expensive then the Cinema 20 HD which as I read it is brighter and a sharper image. What am missing here?

Thanks for the help

The Dell doesnt have the latest DLP chip (HD2 for the Boxlight), it doesnt have a digital interface (DVI), and it doesnt output HDTV resolutions (720p or 1080i).

Probably missing a lot of other features (including advanced picture adjustments), cheaper build, louder, ....

Nope no DVI on the 2200MP but it does run 720P and 1080i (7th line down on the specs)

So a DVI interface (which isn't much better then standard ol' SVGA IMHO) and the H2 Chip is worth nearly $8000 in price increase. That can't be right.

What Rob was alluding to was the fact that the native resolution of the Dell projector is 800x600. It will ACCEPT HD material at 720p or 1080i, but it will downconvert both of these to its native resolution which is NOT HD.

Another big disadvantage to the Dell is it's native 4:3 aspect ratio - certainly not what you would typically want for a home theater.

You mentioned noticing the "rainbow effect" on your friend's projector. The Boxlight DLP projector's 6-segment, 5x speed color wheel substantially lessens the chance that the rainbow effect will be noticeable.

To a lesser extent, it's important to realize that brightness and contrast ratio numbers, as listed in spec sheets, are often measured and arrived at using a wide variety of methods and are often not representative of "real world" operating environments.

In essence, the Dell projector, while it IS DLP, is easily 2 (now nearly 3) generations behind the current state of DLP technology. That's the main reason for the low price compared to the Boxlight.

Keeping the source digital (DVI, HDMI) is very beneficial when using digital (DLP, LCD) displays.

Jason - Thanks for the follow up. I miss the fact that it was 4:3.
