Price

Reasonably Priced

Two owners reckoned that it was good value for money. Expert website Expertreviews.co.uk wrote in their review of this projector “The rainbow effect and high price were more than enough to put us off”. Laszlo Demeter mentioned “Great price, quick delivery! I would do it again anytime in the future if in need” in their review of the Benq SP840 and scored the product a maximum of 5 stars.

The price range of multimedia projectors of this type and age is from £214 to £2,499. We think that this Benq projector looks expensive compared to other multimedia projectors of this type and age.

Multimedia

Has a Built-In Speaker(s)

The Benq SP840 has a built-in speaker(s). Most of the other projectors of a similar age and type to this data projector also have a built-in speaker(s).

We think you might also be interested in some of the other projectors with a built-in speaker(s) currently available including the Hitachi CP-WU8440 (£1,166.66), the Optoma EW695 (£1,298), or the Sony VPL-SW630C (£1,066.99) which all of have better reviews.

Energy

Very High Running Costs

Based on typical energy prices we estimate that the 1 year running cost of the SP840 is £146, which makes it one of the most expensive to run projectors that have been around for more than two years.


Projector

1080p (1920x1080) 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 frequently found resolution.

A 1080p (1920x1080) projector native resolution is actually the best resolution amongst all multimedia projectors that came out more than two years ago.

The worst resolution across similar types of projector is SVGA (800x600).

Across all the multimedia projectors of a similar age and type to this data projector the projector brightnesses range from 100 ANSI lumens to 7,000 ANSI lumens.

Multimedia projectors with a brighter projector brightness that might be worth considering include the Hitachi CP-WU8440 (£1,166.66) (4,200 ANSI lumens and higher rated), or the Sony VPL-CW276 (£1,049.99) (5,200 ANSI lumens and higher rated).
