1. HDTV optical discs will use all standard ATSC formats, 720p60 & 1080i30 & 1080p24.

2. 1080p is both a signal standard and a display format, but they have different framerate capabilities. Image format is 24 frames per second. Display format is 60 frames per second, so it can upconvert 720p60 without dataloss. It is progressive, so it will deinterlace 1080i30 and double refresh it.

3. LCDs as well as DLP & LCOS & DILA & Plasma are inherently progressive.

4. Is not a question... but, yes, a 1080p60 display is the ultimate HDTV format. Ultimate quality is determined not only by the panel res & performance, but also by the upconversion chip.

The only 1080p60 direct view LCD I know of is from Sharp... other sets with DLP, DILA, and LCD as imagers in RPTVs will have 1080p60 models by fall or sooner.
