None of the D450/D490 TVs are 1280x720p; it has been said numerous times by me, that the 43" are 1024x768p and the 51" are 1360x768p; there is scaling in either case. The difference is what type of scaling; up, down, or up and down; this is all detailed in that previous post.

Well, the key is that resolution is being thrown away in unnecessarily downscaling 1920x1080i to 1280x720p, and it can't be recreated properly when the 51" TV upscales vertically and horizontally to the TV's fixed resolution of 1366x768p (or in the case of the 43" TV, it upscales vertically (and downscales horiz.) to 1024x768p).
Never downscale a signal vertically and/or horizontally to less than the panel's fixed resolution; which is what happens with 1080p/i signal going to 720p, and then to TV's 768p fixed resolution. (I left out the horizontal res. to make it simpler, though it matters, as I explained before.)
