10 Reasons For

Benq Has Good Reviews for Its Multimedia Projectors

Benq multimedia projectors have an average rating of 86 out of 100, which is in the top 24% of all projector manufacturers that we have assessed.

Reasonably Priced

Two Benq SP840 reviewers who bought it thought it was good value for money. Four years ago Laszlo Demeter mentioned “Great price, quick delivery! I would do it again anytime in the future if in need”. Expert review site Expertreviews.co.uk said “The rainbow effect and high price were more than enough to put us off” in their review.

Supports Full HD

The Benq SP840 supports full HD, which is unusual. Most of the other similar spec projectors that have been around for around the same time as the SP840 do not support full HD.

Chart Edit

Has a Built-In Speaker(s)

The Benq SP840 has a built-in speaker(s), as do most of the other data projectors that came out around the same time as the SP840.

It may also be worth considering one of the other data projectors with a built-in speaker(s) currently available including the NEC UM330[plb_1525062_price], or the Hitachi CP-WU8440[plb_1857317_price] which has better reviews.

1080p (1920x1080) Projector Native Resolution

The Benq SP840 has a maximum resolution of 1080p (1920x1080). That's over two times the resolution of a WXGA (1280x800) data projector, which is the most common resolution. Projectors of a comparable spec and age to the SP840 projector native resolutions range from SVGA (800x600) (worst) to WUXGA (1920x1200) (best).

Chart Edit

Quite Bright Projector Brightness

The dimmest projector brightness of comparable spec data projectors that were launched around the same time as the SP840 is 100 ANSI lumens, the brightest is 8,000 ANSI lumens, and the average projector brightness is 3,500 ANSI lumens. The Benq SP840 has one of the brighter projector brightnesss (4,000 ANSI lumens) amongst 3000:1 contrast ratio projectors of this age.

If this Benq projector projector brightness is not bright enough for you then you might want to look at the Hitachi CP-WU8440[plb_1857317_price] (4,200 ANSI lumens) which also has a higher rating.

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...
