I'm in the market for a new HDTV, and am considering on getting a 1080p. I understand the concept of what up-conversion is and why it degrades the visual quality on lower source quality materials. But I don't have a feel on what the visual impact of up-conversion will have at different levels of source materials. This is a concern for me as the vast majority of source material available right now will require an up-conversion. For instance what will happen if I do the following?


1) Image quality of a SD signal on a 1080p? (perhaps compared to a decent quality 720 such a Samsung LNT-3253H
)


2) Image quality of a standard DVD on a 1080p? (compared to a 720p up-conversion)


3) Image quality of hdtv standards such as 720p and 1080i signal on a 1080p.


Now lets throw a wrinkle into the mix. My current plans are to buy a 1080p & blu-ray player (which from my understanding is the only thing that currently displays 1080p source material) and make it for watching movies. But what if I buy a 720p or 1080i set. What is the visual degradation in quality, if any?


Thanks for any help.

SD is going to look like crap no matter what you do, because it's SD and unlike a fuzzy CRT, a 1080p LCD will highlight all of the flaws of the original. This goes double for cable SD and triple for overcompressed, downresed satellite SD.


Resizing SD to fit a 1080p display won't degrade the image, since the jump from 720x480 to 1920x1080 is big enough so that pixels can be smoothed out fairly evenly.
