9 Reasons For

Benq Projectors Have Good Reviews

Multimedia projectors built by Benq generally have good ratings compared to other manufacturers.

Supports Full HD

The Benq SP840 supports full HD, unlike most of the other similar spec data projectors that have been available for around the same time as the SP840 which do not support full HD.

Other projectors which support full HD currently available that you might also want to look at include the CP-X5022[pl_1857320_price], or the CP-WX4022[pl_1887899_price] both from Hitachi which has better reviews.

Has a Built-In Speaker(s)

The Benq SP840 has a built-in speaker(s), as do most of the other comparable spec multimedia projectors that have been on the market for more than two years.

We compared all the other data projectors with a built-in speaker(s) to this multimedia projector and we think because of it's better review score, the CP-X5022[pl_1857320_price], and the CP-WX4022[pl_1887899_price] both from Hitachi or the NEC UM330[plb_1525062_price] is also worth considering.

The SP840 is clearly designed for use in well-lit public areas, but the rainbow effect and high price were more than enough to put us off...
