Can a DLP high definition TV billed as 720p display 1080i content without downscaling it?

Question

I know that an LCD or Plasma, which has a finite number of physical pixels across the board, must downscale a 1080i image to 720 resolution before displaying. But can a DLP based set display it at native resolution without scaling? Or would it need to be a 1080p set to display 1080i without scaling?

Answer 1

Any time the display resolution is different from the source resolution scaling is necessary regardless of the type of display. But there is more involved here than just scaling. All fixed-pixel sets (with one recent exception) display progressive scan. This means that 1080i signals must be de-interlaced, and that must be done in in addition to scaling to display 1080i on a 720p set. Some sets don't do this well; they may take the "easy out" by merely scaling the 540 lines of a 1080i field to 720. In this case, the 1080i picture could be worse than a 720p. The better sets de-interlace the 1080i first before scaling, and the quality of that de-interlacing (there are many ways to do it) is more important to the end result than the scaling. A 1080p set will display 1080i without scaling, but not without de-interlacing, so the same potential problems arise.

Answer 2

easily some videophiles favor 720p; in spite of the actual undeniable reality that it has fewer lines of decision, the modern scanning of 720p is better for on the spot action, which comprise events. for this reason Fox is in 720p in basic terms. So the content cloth service impacts your decision too. the acceptable might want to be to get a scaler that could want to scale 720p or 1080i to 1080p if the television does not try this, as some do.
