Hitachi responds on its 1080 HD
Here's the official response from Hitachi. I am reproducing in full in original answer
Following answers to your enquiry:
Hitachi's 42PD8900TA is currently the plasma panel with the highest number of horizontal lines (1080).
This 1080 horizontal lines enables the display of 1080 horizontal lines in HD broadcast (1080i) without pixel alteration.
The result is the world's highest definition for a 42-inch Plasma TV, enabling the reproduction of detailed images.
To enjoy full spec of HD, the panel should have a resolution of 1920 x 1080 for the 16:9 screen aspect ratio.
For Hitachi's 42PD8900TA with resolution of 1024 x 1080, the vertical lines is actually slightly scaled to get the 16:9 aspect ratio.
But, for other XGA plasma with resolution of 1024 x768 or XGA LCD with resolution of 1366x768, these products need to do both horizontal & vertical scaling to display 1080i HD signal.

if 1920 scale down to 1024 is slightly, then my `brother' is slightly big only.
Ask them: which will be better, 1366x768 scale up from 576p, or 1920x1080 scale down to 1024x1080
And don't forget the Starhub box may also output 720p, but this I must see.
dun we lose almost 50% of the horizontal info?
Definitely plasma is not the choice for watching HD content. 50% scaling is just beyond the acceptable range.
Guys - you miss the point! Most sets on todays market, except for 1080p ones will need to scale on the vertical axis AND horizontal axis. The Hitachi with its 1080 of horizontal lines only has to scale one axis. Further, other sets whether 1024, 1280 or 1366 in resolution also need to scale significantly for 1920 transmission
