What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.8 for now.

Third-party reviews

What customers like about Casio XJ-A251

  • Long-lasting hybrid laser/LED light source with up to 20,000 hours of life
  • Highly portable, ultra-slim 'A4-size' design weighing approximately 2.3kg
  • Powerful 2x optical zoom providing significant placement flexibility
  • Fast start-up and instant power-down without a cooldown period
  • Maintenance-free operation with no lamps or filters to replace
  • Automatic brightness adjustment based on ambient room light

What customers don't like about Casio XJ-A251

  • Prone to the 'rainbow effect' (RBG flashes) common in single-chip DLP projectors
  • Internal speakers (1-watt mono) are generally considered weak for large rooms
  • Fan noise can be significant and distracting when operating in high-brightness modes
  • Lower color accuracy compared to dedicated home theatre models
  • Limited connectivity options compared to modern 1080p projectors
  • Native resolution is limited to WXGA (1280x800), not full HD

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.
