BenQ SP840 review


The BenQ SP840 is a stunningly bright projector with a 4,000 lumens lamp. It means that you should be able to use it in any room without having to dim lights or close curtains. This brightness also makes the SP840 far more suitable as a living room TV...

The SP840 is clearly designed for use in well-lit public areas, but the rainbow effect and high price were more than enough to put us off.
