Summarizing the truths around here:
- 1080p is 1080 lines or vertical resolution, 720p is 720 lines or vertical resolution. Then, you can have any horizontal resolution you want. Usually, for movies, it's 1920x1080 because that's a 16/9 ratio, and 1280x720 for the lower HD resolution, for the same reason. But 960x1080 is still 1080p. The human eye is more sensitive to vertical resolution, which is why we use the vertical resolution to describe the standards, not the horizontal one. Stretching the horizontal resolution is no big deal actually, even if x2 should be the limit, but the eye won't notice it as much as if it was the vertical resolution.
- 1080p is immediately noticeable as far better than 720p on sets 40" and higher (at the right distance range, of course). Only delusional people say otherwise.
- The difference between 30 fps and 60 fps is not noticeable by the human eye, except by very gifted or trained people perhaps. The eye is fooled as soon as 24 fps actually. The brain notice going from 30 fps to 60 fps, when you have to interact with what you see. In this case, the brain clearly sees the lag between the action taken and what happens on the screen, and is disturbed. At 60 fps, the brain won't notice the lag, except with very gifted people.
