i'm interested in but i want to know if 1080p is worth the extra money vs. the cheaper set with only 1080i.
Unless you are looking at buying a CRT set, a TV that is labeled “1080i”
will be displaying anything it receives as 1080p. The reason being that, only CRT can display an interlaced signal as interlaced; every other display technology must de-interlace.
Also any TV that is 1080i or p should have a native resolution of about two million pixels, allowing it to display any 1080 signal pixel for pixel, so the real question is; do any of these sets accept a 1080p input?
The reason for that question is because if you plain to get HD DVD or Blu-ray, they are native 1080p, the highest resolution HDTV broadcast is in is 1080
i.
And depending on how far you sit from your screen, and how much 1080 content you watch, you may be able to get a better quality TV that is 720p for the money of a 1080 set.
