Verdict

The Casio XJ-A251 is an ultra-slim, portable DLP projector featuring a mercury-free Laser & LED Hybrid light source that provides 3,000 ANSI lumens of brightness and a native WXGA (1280 x 800) resolution. Main characteristics include a 20,000-hour light source life, a 2x power optical zoom with motorized focus, and a highly compact frame measuring just 1.7 inches thick. Primary pros consist of its rapid 8-second startup, low maintenance costs due to the lamp-free design, and excellent portability for business travelers. Some reported cons include a relatively low contrast ratio of 1800:1, potential fan noise at full brightness, and a limited 1W mono internal speaker.
