Better framerate, resolution and sharpness than 1080i and 720p.
1080 means resolution of 1920x1080, p menas progressive.
Progressive displays do not suffer from the deficiencies present on interlaced (1080i).
Friend of guy1: 1080p is definitely the best, you would make a big mistake if you bought 1080i because that would be worse than 720p. Don't get the marketing trick you to think same resolution means same quality.
