While most portable digital projectors for business use aren't meant to double as home-theater projectors, reviews say the Optoma EP1690 handles video better than most. It has a widescreen display and an HDCP-compliant DVI input, so it can display HDTV when hooked up to a cable box or other tuner. Reviews say the fan makes quite a hum, but it's not too intrusive during presentations. Reviews say it's bright enough for fairly large rooms, displays text very well and includes a laser pointer. There's a two-year warranty. If you don't need a widescreen, the Dell 2400MP (*est. $1,200) offers more brightness for the same price.
ProjectorCentral.com and ProjectorReviews.com specialize in projectors, test them objectively and reach essentially the same conclusion: The Optoma EP1690 is a great bargain for a widescreen projector, but only if you really need widescreen. The fact that Audioholics.com, geared to home-theater users, even reviews the Optoma EP1690 at all tells you the video output is better than you'll find from most business/classroom projectors. There is just a handful of user reviews at ProjectorCentral.com, but triple what you'll find at Amazon.com.
Reviewer Bill Livolsi gives the Optoma EP1690 very good grades, especially for price, with the lowest grade assigned to ease of use. The image quality is good enough for occasional video use, but the fan produces a "low hum" that isn't as quiet as some but still OK for the classroom.

The Optoma EP1690 gets a "Hot Product Award," and has "the lowest selling price (for a) business widescreen projector out there so far." But it says that if you're primarily going to use it for business, you may not need a widescreen, so why pay more for one?

Audioholics publishes thorough, unbiased reviews, geared more to home users than business people. The Optoma EP1690 gets good ratings for "eye-popping" color saturation and "lots of features," but the fan noise is "intrusive."
