InFocus IN81 DLP Projector


Filling the gap between InFocus' top entertainment model and its lower-specced range is the IN81. Any good, John?

Does the IN81 fall short of the glories of the InFocus IN82? Yes it does. But does it nonetheless outperform its £2k asking price by a country mile? You'd better believe it.

Colors lack neutrality in the factory setup., BrilliantColor has some side effects., Loud fan-noise.

DLP fans will love the easy-to-use InFocus IN81, which combines bright pictures and excellent picture quality with an attractive price. One important point: This projector doesn’t offer much flexibility, so you need to be able to put it in an ideal...
