    Thought I would place an inviting topic,

    So how do you pick out a data projector from a HT projector?

    Just by reading the lable? or can some of the data projectors solely for HT.

    One HUGE difference between HT and business PJs is the color wheel. If you find a DLP PJ with a lumen output of 2,000 or more you can bet it has a 4 segment color wheel with the white segment. Most HT PJs have a 6 segment color wheel with 2 sets of red, green, and blue. HTs will also have fancier lenses and scalers/deinterlacers.

    The 6 segment wheel produces more vivid color. The 4 segment wheel provides a very bright but somewhat washed out image.

    I have the 8220 solely for home theater use and it is great. More and more people seem to be getting it. There is a threat on AVS forum right now about this projector, among others.

    Where do you find the segment wheel spec? I have looked at the BenQ website and, but haven't noticed anything on that.
