8 Reasons For

Expert Reviews Are Good

This multimedia projector received an expert rating of 80% from PC Mag.

Benq Has Good Reviews for Its Multimedia Projectors

Benq is one of the better rated projector manufacturers according to average reviews from experts and owners, and Benq also has good ratings for its projectors.

Has a Built-In Speaker

The Benq SW921 has a built-in speaker. Most of the other data projectors that are a similar age to the SW921 also have a built-in speaker.

It may also be worth considering one of the alternative projectors with a built-in speaker currently available including cheaper projectors such as the Optoma W320UST[plb_2940693_price].

Supports 3D Image Projection

The Benq SW921 supports 3D image projection, as do most of the other projectors that were released more than a year ago.

We compared all the other projectors which support 3D image projection to this multimedia projector and we think cheaper projectors such as the Optoma W320UST[plb_2940693_price] is also worth considering.

Quite Bright Projector Brightness

The dimmest projector brightness of multimedia projectors of this age and spec is 500 ANSI lumens, the brightest is 8,200 ANSI lumens, and the average projector brightness is 3,400 ANSI lumens. With a projector brightness of 5,000 ANSI lumens, the Benq SW921 has a quite bright projector brightness compared to most of the other comparable spec data projectors that were released one year ago.

Chart Edit

1600 X 1200 (UXGA) Graphics Resolution

The Benq SW921 supports a maximum resolution of 1600 x 1200 (UXGA). That's over six times the resolution of the most common graphics resolution of 640 x 480 (VGA) (which is also supported by this projector). Across all projectors that have been around for around the same time as the SW921 the resolution ranges from 640 x 480 (VGA) (worst) to 1920 x 1200 (WUXGA) (best).

Very High RMS Rated Power

The lowest RMS rated power of projectors that were released around the same time as the SW921 is 1.5W, the highest is 20W, and the average RMS rated power is 6.9W. With an RMS rated power of 20 Watts, the Benq SW921's RMS rated power is one of the highest amongst comparable spec multimedia projectors that were released one year ago.

9 Reasons Against

Does Not Support Full HD Projection

The Benq SW921 does not support Full HD projection, although this is within the context that most of the other projectors of a comparable spec and age to the SW921 also do not support Full HD projection.

Chart Edit

Does Not Support WiFi Connectivity

Like most of the other projectors that have been around for a comparable time to the SW921, the Benq SW921 does not support WiFi connectivity.

Chart Edit

Running Costs Are Very High

Based on typical energy prices and usage levels we estimate that the 1 year running cost of the SW921 is £161, which makes it one of the most expensive to run projectors that were launched more than a year ago.

Pricey

Multimedia projectors that were released more than a year ago have service life of lamp in economic mode of between 2,500h and 10,000h, and the average service life of lamp in economic mode is 6,800h.

Chart Edit
