9 Reasons For

Benq Has Good Reviews for Its Projectors

We calculated the average reviews for all Benq multimedia projectors and also specifically for Benq 13000:1 contrast ratio multimedia projectors and found that in both cases Benq had good reviews.

Supports 3D

The Benq MX842 supports 3D. Most of the other 13000:1 contrast ratio multimedia projectors that are a similar age to the MX842 also support 3D.

Other projectors which support 3D currently available that you might want to consider include the Benq MW820ST[plb_1552199_price] which is cheaper; or the Benq MX819ST[plb_1552200_price] which has better reviews.

We compared all the other projectors which also support 3D to this multimedia projector and we think the Acer S1383[plb_2711752_price] is also worth considering.
