The video processing technology within the mCable enhances and filters all progressive video content. On some types of content, the difference will not be as obvious as on other types of content. Enhancements will also be more or less obvious depending on your equipment (source device and TV). The video output from the mCable, however, will ALWAYS be better, cleaner, sharper, or at least the same, as the original content. One of the easiest tests if you want to see the difference for yourself at home is to play a DVD and turn on closed captioning / subtitles (but make sure your DVD player is outputting 480p).
