9 Reasons For

Expert Reviews Are Good

Projector expert review site PC Mag scored this projector 80%.

Benq Has Good Projector Reviews

On average Benq data projectors have good reviews as do all projectors manufactured by Benq.

Supports 3D

The Benq SW921 supports 3D, as do most of the other data projectors that were launched around the same time as the SW921.

We think you might also be interested in some of the other projectors which support 3D currently available including the W320UST[pl_2940693_price], or the GT5000[pl_3141494_price] both from Optoma which is cheaper.

Has a Built-In Speaker(s)

Like most of the other comparable spec data projectors that came out around the same time as the SW921, the Benq SW921 has a built-in speaker(s).

We think you might also be interested in some of the alternative multimedia projectors with a built-in speaker(s) currently available including cheaper projectors such as the W320UST[pl_2940693_price], or the GT5000[pl_3141494_price] both from Optoma.
