Processors does de-interlacing (doubling,) scaling to your panel's native resolution, various filtering, noise reduction and picture cleanup.Probably the hardest part is de-interlacing, and that is where the native display's build-in unit are at its worst. With a doubler like the DVDO, it will do the de-interlacing, and the display will do the scaling. With a scaler, it will do de-interlacing and scaling. The misc stuff like noise reduction depends on the individual unit.
A good bet for fixed resolution device is a Faroudja NR. It only has 1 resolution, but you only need 1. It has excellent de-interlacing and scaling capability. It goes for $3-$4k. Price no object would be the Teranex, which goes for >$30k, but has 1000x the computing capability of something like the NR, so it could do video de-interlacing on a pixel by pixel basis, applying different algorithm to each pixel, depending on what that pixel's temporal properties are. Whereas the NR would apply different algorithms to different region based on a field of info, the Iscan would do a region based on a frame of info, and the Quadscan would apply the same algorithm to the whole frame.
