10 Reasons For

Good Brand

13000:1 contrast ratio projectors built by Benq have good reviews on average compared to other manufacturers. We also checked the reviews for all projectors (not just 13000:1 contrast ratio projectors) and found that Benq also has good reviews across its entire range.

Supports 3D

The Benq MX842 supports 3D. Most of the other 13000:1 contrast ratio projectors that came out around the same time as the MX842 also support 3D.

We think you might also be interested in some of the alternative projectors which support 3D currently available including the Benq MX806[plb_2515298_price] which is cheaper.

We compared all the other projectors which also support 3D to this data projector and we think the MW843[pl_2417382_price], or the MW821ST[pl_1521593_price] both from Benq is also worth considering.
