Question about my missing 720 mode

Archived from groups: alt.tv.tech.hdtv (More info?)

ABC, FOX, and ESPN are 720p. Your tv probably has an internal scaler to
scale 720p signals to 1080i for these stations.

It depends on the display technology. DLP, LCD, and plasma have a fixed
number of pixels and you have to convert your signal to match that native
resolution. This particular set does not have a single "native resolution"
since it is CRT. It will display 480i/480p/1080i. If you're giving it a
signal via component video connections it needs to be one of those three
resolutions (unlike DLP which will scale all inputs to be 720p). However,
the built-in HD tuner should scale 720p broadcasts to display as 1080i.

For example, the manual for the Sony LCD rear-projector KDF-60XS955 states
that all signals are displayed at 788p. 1368 dots X 768 lines.
