Samsung SP-A400B movie and business projector
The Wash & Go of the projector market
As far as colour response goes, the SP-A400B does indeed perform a lot better than a business-oriented projector. Not only is it able to display a wide range of vivid colours, but it’s also capable of keeping those colours accurate, natural-looking and film-like. This is helped, in part by the use of HP’s BrilliantColor technology, which enables a standard three-colour light-filter wheel to produce six distinct colour channels.
By making use of the brief period of time when the wheel is shifting from one colour to the next, the projector is able to effectively mix those colours. The shift from red to green, for example, would produce yellow light. Processing six colours instead of three, allows you to produce much smoother and more realistic hues.
A comprehensive selection of connections
However, while the Samsung is certainly better for movies than a straightforward business-oriented model would be, there are many dedicated home cinema projectors that are able to deliver more. Again, Optoma’s tiny HD65 is capable of displaying a more contrasty image with punchier colours. It may not look as sexy as the Samsung, but it's much cheaper.
Samsung has designed a single projector and is trying to promote it to two different types of customer: business users and consumers. It's found a good balance between the two usage modes, but unless you plan to use the same projector in the office and at home.
It would seem to make more sense to buy one that's tuned to the environment it'll be used in.
