The hardware properties of the XJ A257 manufactured by Casio include 3000 ANSI lumens, a WXGA 1280 x 800 resolution and a contrast value of 1800:1. As an LED projector, the spec sheet indicates a lifespan of 20000 hours – equivalent to a usable life of 13.7 years at 4 hours a day. Regarding projection size, the value of 3000 ANSI lumens allows for an image width of up to 556 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 371 cm. The projector was released in 2014 and is officially no longer distributed by Casio.
