You're got two displays; perhaps a plasma on the wall for day-to-day viewing and a projection screen that drops down in front of it for serious movie watching. Or you want to feed HDMI video to a small screen on your equipment rack as a monitor. Or…whatever. Up to now, it's been difficult to find an affordable device that will split an HDMI source in two. There are a number of such products on the market from companies like Gefen, Key Digital, and PureLink, but they tend to be expensive solutions to a relatively basic problem, often providing more flexibility than you need.

LCD flat panels may be the hot ticket in the TV market these days, but plasmas shouldn't be counted out by any means. For example, they offer superior off-axis viewing and generally better black levels. Not only that, large plasmas are often less expensive than LCDs of similar size.
