10 Reasons For

Good Brand

Based on 2,080 expert and user reviews, Benq has good reviews for its projectors. Benq also has good reviews specifically within its 13000:1 contrast ratio projectors range compared to other brands.

Supports 3D Image Projection

The MW821ST supports 3D image projection. Most of the other 13000:1 contrast ratio projectors that have been available for a comparable time to the MW821ST also support 3D image projection.

We think you might also be interested in some of the alternative multimedia projectors which support 3D image projection currently available including the Benq MX816ST which is cheaper; or the Benq MX768 ($1,899.00) which has better reviews.

Other data projectors which also support 3D image projection that you might also want to look at include the Benq MW843 ($1,198.99).

Has a Built-In Speaker

Like most of the other 13000:1 contrast ratio projectors that are a comparable age to the MW821ST, the MW821ST has a built-in speaker.

Other data projectors with a built-in speaker currently available that you might want to consider include the Benq MX816ST which is cheaper; or the Benq MX768 ($1,899.00) which has better reviews.

We compared this multimedia projector to all the other projectors with a built-in speaker and we think the Benq MW843 ($1,198.99) is also worth considering.
