10 Reasons For

Benq Data Projectors Have Good Reviews

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

Supports 3D Image Projection

The Benq MW843 supports 3D image projection. Most of the other similar spec projectors that have been around for a comparable time to the MW843 also support 3D image projection.

We compared all the other projectors which support 3D image projection to this data projector and we think the Optoma DH1011[plb_1726991_price] which has better reviews is also worth considering.

There are a number of alternative projectors which also support 3D image projection which you might want to look at including the Benq 720P[plb_1560816_price], or the Optoma ML800[plb_1966220_price].
