There's a big difference between a HDTV that:
Supports 1080i, but in reality needs to downconvert it to 720 or 768 to fit the screen resolution,
And a HDTV that has 1080 line resolution, and doesn't need to downconvert.
Actually, it's more complicated than that. Most 1080i HDTVs actually process two 540p images. To fit these alternating images on an HDTV with 768 lines requires a great deal of manipulation.
In a year, most new HDTVs 37 inches or larger will have 1080 lines. Thank goodness.
It has 1080p native resolution - Jack G 04:38:40 03/28/06 (3)
But doesn't accept 1080p input. As I understand it, the chips alowing 1080p input either weren't available, or more likely, they were more expensive. For me its a non-issue.

- $3.50 vs $6.50 - Joe Murphy Jr 18:24:20 03/29/06 (2)
  That's the difference in price between 1080i/720p and 1080p for Silicon Image HDMI chips.
  - 1080p = hi-end? - La Dolce Vita 22:19:45 03/29/06 (1)
    That's why they can charge you extra $3k for the 1080p chip that cost $3 more to them.
    - the display manufacturer sets the retail price - Joe Murphy Jr 20:32:54 03/30/06 (0)
      SI wants $3 more for the full HD capable chip (1920x1080p). The manufacturer -- not SI -- decides what value that gives to their product.
