Sometimes your display doesn’t have such a great scaler / video processor. In that case you might want to look into something from VDO or from this company, Algolith. The have a processor they call the Dragonfly, based on Realta’s HQV technology.

The Dragonfly will up- or down-scale, de-interlace and cadence-correct all video signals from 480i to 1080p. A key feature of the unit is its true 1080i and 1080p de-interlacing capability, which uses the full four-field processing window for HD video de-interlacing and cadence detection, preserving rich details in HD imagery, rather than discarding half the resolution, as the firms says conventional image processors do.

The suggested price of the Dragonfly is $2,995. That’s as much as some pretty good projectors, so I have to wonder. You’ll buy a processor like this if you have the money to spend to buy a really expensive display. And if you have such a display, won’t it include processing adequate to the task? I know that not all scalers are created equal, but some displays even include Realta’s HQV technology, so where’s the sense in that? Is this processor only meant for display not equipped with such?
