7 Reasons For

Very Low Running Costs

Based on typical usage levels and energy prices we estimate that the XJ-A251 will cost only £71 over 1 year to run, which is in the cheapest 9% of all 85 multimedia projectors of a comparable age and type.

Has a Built-In Speaker(s)

Like most of the other 2000:1 contrast ratio data projectors that were released more than two years ago, the XJ-A251 has a built-in speaker(s).

1600 X 1200 (UXGA) Supported Graphics Resolutions

The XJ-A251 supports a maximum resolution of 1600 x 1200 (UXGA). That's over six times the resolution of the most common supported graphics resolutions of 640 x 480 (VGA). This multimedia projector also support supported graphics resolutionss of 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1280 x 768 (WXGA), 1400 x 1050 (SXGA+) and 1680 x 1050 (WSXGA+) and 800 x 600 (SVGA). The best resolution of all 2000:1 contrast ratio data projectors that were released more than two years ago is 1920 x 1200 (WUXGA) and the worst is 640 x 480 (VGA).

Chart Edit

WXGA (1280x800) Projector Native Resolution

The Casio XJ-A251 has a maximum resolution of WXGA (1280x800). That's 30% more resolution than a XGA (1024x768) multimedia projector, which is the most frequently found resolution. Data projectors of a similar spec and age to the XJ-A251 projector native resolutions range from XGA (1024x768) to WUXGA (1920x1200).

Chart Edit

Fairly Long Service Life of Lamp

At 20,000 hours, the XJ-A251 has a fairly long service life of lamp compared to most of the other projectors of this type and age. Across all the 2000:1 contrast ratio data projectors that have been available for a comparable time to the XJ-A251 the service life of lamps range from 200h to 30,000h, and the average service life of lamp is 5,200h.

Very Light

At only 2.3 kilograms, the XJ-A251 is quite light compared to most of the other projectors of this age and spec. The average weight of similar spec projectors that have been around for around the same time as the XJ-A251 is 6.5kg, and the weights range from 370g to 23kg.

Chart Edit

Quite Quiet Noise Level (economic Mode)

The XJ-A251 has one of the quietest noise level (economic mode)s (only 26 decibels) amongst comparable spec projectors of this age. Across all the 2000:1 contrast ratio data projectors that came out around the same time as the XJ-A251 the noise level (economic mode)s range from 26dB to 37dB, and the average noise level (economic mode) is 30dB.

8 Reasons Against

Casio Only Has Unexceptional Reviews for Its Projectors

On average Casio projectors are rated 70 out of 100, which is in the bottom 24% of all projector manufacturers that we have assessed.

Does Not Support Full HD

The XJ-A251 does not support full HD, although it is worth noting that most of the other 2000:1 contrast ratio data projectors that are a comparable age to the XJ-A251 also do not support full HD.

Alternative projectors which also support full HD that you might also want to look at include the AAXA Technologies LED Android Pico Projector[plb_3156294_price] which is also higher rated.

Does Not Support 3D

The Casio XJ-A251 does not support 3D, although keep in mind that most of the other projectors that have been on the market for more than two years also do not support 3D.

We compared all the other multimedia projectors which also support 3D to this projector and we think the NEC U310W[plb_1531485_price] which is also higher rated is also worth considering.

Does Not Support Wi-Fi

The XJ-A251 does not support wi-Fi. Most of the other comparable spec projectors that are a similar age to the XJ-A251 also do not support wi-Fi.

We compared all the other projectors which also support wi-Fi to this multimedia projector and we think the Epson PowerLite 1761W[plb_1735741_price], or the AAXA Technologies M2 Micro[plb_1759924_price] is also worth considering.
