Diamond Series WD73835 uses a high speed video processor called Plush1080p that upconverts 1080i signals to 1080p producing four times the resolution of traditional line doublers. HDTVs can display any video signal. For a 1080p HDTV, even the high quality 720p and 1080i HDTV signals being broadcast need to be reformatted in order to fill the TV screen with a sharp, clear picture.
