i was talking to a rep from hitachi today and he was trying to explain the ALIS panel to me. Can someone please explain if this is of any benifit to a plasma display? Of course he was beaming brightly about this saying its a hitachi only product but has/is this in any other pdp of lcd?
Is it any good?

Have a look here http://av.hitachi.com/tv/plasma/quality/index.html

Thre Hitachi ALIS panel is a Plasma, but uses a new type of technology to display the image directly without scaling.

As it's ultimately a TV that we view our Sat channels on, I'd say it was related.

You need to read the webpage more carefully! - it only displays HD without scaling - exactly as any other Full HD set does (either LCD or Plasma).

If you fed the set 720P HD, then it would have to scale it, as it always does SD - again, exactly as all Full HD sets.

ALIS is not exactly new and despite the claims that it is better for showing high motion images, I am yet to be impressed with the current generation of Hitachi plasmas over other makes such as Panasonic and Pioneer.
