8 Reasons Against

Does Not Support Full HD Projection

Most multimedia projectors of a similar age and type to the XJ-A251 do not support Full HD projection. The XJ-A251 is no exception to this as it too does not support Full HD projection.

We compared all the other data projectors which also support Full HD projection to this data projector and we think the AAXA Technologies LED Android Pico Projector[plb_3156294_price] which also has a higher rating is also worth considering.

Does Not Support 3D Image Projection

The XJ-A251 does not support 3D image projection. Most of the other projectors of a similar spec and age to the XJ-A251 also do not support 3D image projection.

Chart Edit

Does Not Support WiFi Connectivity

The Casio XJ-A251 does not support WiFi connectivity. Most of the other projectors of a comparable age and spec to the XJ-A251 also do not support WiFi connectivity.

It is worth also looking at other projectors which also support WiFi connectivity including the AAXA Technologies M2 Micro[plb_1759924_price].

Across all similar spec projectors that were released more than two years ago the resolution ranges from 640 x 400 (worst) to 4096 x 2160 (best).

Chart Edit

Quite Small Lamp Power

When compared to other multimedia projectors of this type and age that we have assessed the lamp power of, the Casio XJ-A251's lamp power of only 170 Watts is one of the smallest. 2000:1 contrast ratio data projectors that were released more than two years ago have lamp power of between 170W and 4,000W, and the average lamp power is 320W.

Chart Edit

Very Low RMS Rated Power

The average RMS rated power of projectors that are a similar age to the XJ-A251 is 6.9W. With an RMS rated power of only 1 Watt, the XJ-A251 has a fairly low RMS rated power compared to most of the other projectors of this type and age.

Chart Edit

Only One VGA (D-Sub) Port

Most 2000:1 contrast ratio data projectors that were launched around the same time as the XJ-A251 have between one and three VGA (D-Sub) ports, including the XJ-A251 which has one VGA (D-Sub) port.

Chart Edit

Only One USB 2.0 Port

The XJ-A251 is a one USB 2.0 port multimedia projector. Most of the other projectors that came out around the same time as the XJ-A251 have between one and two USB 2.0 ports.
