Question

Is a tv with 1366x768 resolution 720p or 1080i?

Answer 1

Actually, it's neither.

720p = 1280x720, non interlaced

1080i = 1920x1080, interlaced

Any time an HD set receives a signal that's not its native resolution, it converts it to whatever the native resolution is.  Most people would call that set a 720p set, but realize, that there will be up or down conversion done on any signal passed to that TV, since nothing is broadcast in 768i or 768p.

Have a peek at Wikipedia so you can see what all the different acronyms map to in terms of actual resolution:

http://en.wikipedia.org/wiki/1080i

Answer 2

720p is it's native resolution. It can probably ACCEPT a 1080i signal, but it will downscale it to 720p. Check your manual if you still have it to see what different resolution signals it can accept.
