11 Reasons For

Good Brand

Projectors made by Benq have an average rating of 86%, which is in the top 27% of all multimedia projector manufacturers that we have analysed.

Reasonably Priced

Several Benq SP840 owners who reviewed it concluded that it was good value for money. Laszlo Demeter mentioned on Amazon three years ago “Great price, quick delivery! I would do it again anytime in the future if in need” in their Benq SP840 review. Expert review site Expertreviews.co.uk said “The rainbow effect and high price were more than enough to put us off” in their review of the Benq SP840 but they scored it 40 out of 100.

£147.98 Price Drop

In the last couple of weeks the SP840 has dropped in price by £147.98.

Supports Full HD Projection

The Benq SP840 supports Full HD projection. Most of the other data projectors of a similar age and type to the SP840 do not support Full HD projection.

Chart Edit

Has a Built-In Speaker

The Benq SP840 has a built-in speaker. Most of the other projectors of a comparable type and age to the SP840 also have a built-in speaker.

We compared all the other multimedia projectors with a built-in speaker to this multimedia projector and we think the NEC UM330[plb_1525062_price], the Hitachi CP-WU8440[plb_1857317_price], and the Optoma EW695[plb_1719594_price] which has better reviews is also worth considering.

1080p (1920x1080) Native Projector Resolution

The highest resolution of the Benq SP840 is 1080p (1920x1080). That's over two times the resolution of the most common native projector resolution of WXGA (1280x800). Across all data projectors that have been around for a comparable time to the SP840 the best resolution is WUXGA (1920x1200) and the worst is SVGA (800x600).

Chart Edit

Fairly Bright Projector Brightness

With a projector brightness of 4,000 ANSI lumens, the Benq SP840 has one of the brighter projector brightness amongst projectors of this age. The dimmest projector brightness of projectors of this age and type is 100 ANSI lumens, the brightest is 8,000 ANSI lumens, and the average projector brightness is 3,500 ANSI lumens.

If this 3000:1 contrast ratio projector projector brightness is too dim for you then you might also want to consider the Hitachi CP-WU8440[plb_1857317_price] (4,200 ANSI lumens) which is also higher rated.

1920 X 1080 (HD 1080) Graphics Resolution

The highest resolution supported by the Benq SP840 is 1920 x 1080 (HD 1080). That's 8% more resolution than the most frequently found graphics resolution of 1600 x 1200 (UXGA). In addition, this multimedia projector supports a graphics resolution of 640 x 480 (VGA). Data projectors of a comparable type and age to the SP840 graphics resolutions range from 640 x 480 (VGA) to 1920 x 1200 (WUXGA).

Chart Edit

Two HDMI Ports

The Benq SP840 has more HDMI ports than most of the projectors that have been around for a similar time to the SP840. Most of the comparable spec projectors that are a similar age to the SP840 only have one HDMI port, however this data projector has two HDMI ports.

Chart Edit

Quite Big Lamp Power

3000:1 contrast ratio projectors that have been around for around the same time as the SP840 have lamp power of between 140W and 400W. The Benq SP840 has a quite big lamp power (300 Watts) compared to most of the other 3000:1 contrast ratio projectors that were released more than two years ago.

Chart Edit

100V AC Input Voltage

This data projector has a 100 - 240V AC input voltage, which is the most frequently found AC input voltage on 3000:1 contrast ratio projectors that have been available for more than two years.

11 Reasons Against

Expert Reviews Are Poor

Expert review site Expert Reviews scored this multimedia projector 40%. It seems that projector experts really don't rate this projector very highly.

Does Not Support 3D Image Projection

The Benq SP840 does not support 3D image projection, although it is worth keeping in mind that most of the other data projectors that were released more than two years ago also do not support 3D image projection.

We compared this multimedia projector to all the other multimedia projectors with a 3D image projection and we think the Optoma EW695[plb_1719594_price] which is also higher rated is also worth considering.

Read more Less Chart Edit

Does Not Support WiFi Connectivity

The Benq SP840 does not support WiFi connectivity, although it is worth keeping in mind that most of the other projectors that have been available for a similar time to the SP840 also do not support WiFi connectivity.

There are a number of other projectors which also support WiFi connectivity that you might want to consider including the Sony VPL-SW630[plb_2442309_price] 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...
