When to use a Line Doubler?
A line doubler de-interlaces a video image and creates a “cleaner” video picture that does not interlace and jitter. When a video image or movie is played on a wide screen data projector, the output of the line doubler is connected to the Data Input of the projector, normally reserved for computer VGA data. A good line doubler that uses interpolation algorithms creates a high quality, movie-like image on the screen.
