9 Reasons For

Benq Has Good Reviews for Its Projectors

We calculated the average reviews for all Benq projectors and also specifically for Benq 13000:1 contrast ratio projectors and found that in both cases Benq had good reviews compared to other manufacturers.

Supports 3D Image Projection

Like most of the other comparable spec projectors that came out more than two years ago, the Benq MX842 supports 3D image projection.

It may also be worth considering one of the alternative projectors which support 3D image projection currently available including a cheaper data projector such as the MX806[pl_2515298_price], or the 720P[pl_1560816_price] both from Benq or you might consider a better rated data projector such as the Benq MW526[plb_2415513_price].

Read more Less Chart Edit

Has a Built-In Speaker

The Benq MX842 has a built-in speaker. Most of the other 13000:1 contrast ratio projectors that were launched more than two years ago also have a built-in speaker.

We compared this projector to all the other projectors with a built-in speaker and we think a cheaper projector such as the Optoma EW556[plb_1717954_price], and the Acer P1276[plb_1563560_price] or you might consider a higher scoring projector such as the Benq MW526[plb_2415513_price] are also worth considering.

1600 X 1200 (UXGA) Graphics Resolution

This projector supports a graphics resolution of 1600 x 1200 (UXGA)|640 x 480 (VGA), which is typical of many comparable spec projectors that have been available for a similar time to it.

Chart Edit

Very Big Offset

With an offset of 153 percent, the Benq MX842 has a very big offset compared to most of the other projectors that were launched more than two years ago. The offsets of 13000:1 contrast ratio projectors that were released more than two years ago range from 100% to 160%, and the average offset is 120%.

Chart Edit

Fairly High RMS Rated Power

With an RMS rated power of 20 Watts, the Benq MX842 has a quite high RMS rated power compared to most of the other multimedia projectors that have been on the market for around the same time as the MX842. Comparable spec projectors that were released more than two years ago have RMS rated power of between 2W and 20W, and the average RMS rated power is 7.3W.

Chart Edit

Two Built-In Speakers

The Benq MX842 is a two built-in speaker projector.

Chart Edit

Quite Long Service Life of Lamp in Economic Mode

Across all the data projectors of a comparable spec and age to the MX842 the service life of lamp in economic mode range from 3,000h to 10,000h. The Benq MX842 has a quite long service life of lamp in economic mode (7,000 hours) compared to most of the other data projectors of this type and age.

Chart Edit

Quite Big Lamp Power

Projectors of a similar age and spec to the MX842 have lamp power of between 190W and 310W. The Benq MX842 has one of the bigger lamp power (240 Watts) amongst 13000:1 contrast ratio projectors of this age.

Chart Edit

6 Reasons Against

Does Not Support Full HD Projection

The Benq MX842 does not support Full HD projection, although keep in mind that most of the other 13000:1 contrast ratio projectors that have been around for more than two years also do not support Full HD projection.

Other data projectors which also support Full HD projection that you might want to look at include the MX806[pl_2515298_price], the MW820ST[pl_1552199_price], or the MS512[pl_2290289_price] all from Benq which is also cheaper.

Read more Less Chart Edit

Does Not Support WiFi Connectivity

The Benq MX842 does not support WiFi connectivity. Most of the other multimedia projectors of a similar age and spec to the MX842 also do not support WiFi connectivity.

Chart Edit

Only Fixed Zoom Ratio

This multimedia projector supports a Fixed zoom ratio, which is the most frequently supported zoom ratio on projectors that have been around for around the same time as it.

Chart Edit

Very Short Lamp Service Life

With a lamp service life of only 3,500 hours, the Benq MX842 has one of the shorter lamp service lives amongst 13000:1 contrast ratio projectors of this age. Projectors of this spec and age have lamp service lives of between 2,500h and 20,000h, and the average lamp service life is 4,600h.

Chart Edit

Very Heavy

The weights of multimedia projectors of a comparable spec and age to the MX842 range from 1.3kg to 5.4kg. When compared to other 13000:1 contrast ratio projectors that were released more than two years ago that we have assessed, the weight of the Benq MX842 of 5.4 kilograms is one of the heaviest.

Chart Edit

Expensive

We think this data projector looks expensive compared to other projectors of a comparable age and spec. We checked 32 projectors of a comparable age and spec and they range in price from £247 to £1,002.

4 Other reasons to consider the Benq MX842

Released Over Two Years Ago

This projector was released over two years ago.

OK Running Costs

Based on average energy prices and usage levels we estimate that the 1 year running cost of the MX842 is £106, which is typical compared to the other 72 projectors of this age and spec.

Average Projector Brightness

At 3,000 ANSI lumens, the Benq MX842 has a pretty typical projector brightness compared to most of the other multimedia projectors that are a comparable age to the MX842.

We think you might also be interested in some of the alternative 3,000 ANSI lumens brightness projectors currently available including the MW820ST[pl_1552199_price], or the MS512[pl_2290289_price] both from Benq which is cheaper.
