Resolution is only one determinant of HDTV quality. Widescreen CRTs will output 1080 x 850 (approximately) in a 3x4 window. I forget what the extrapolated horizontal resolution is, I calculated it once and promptly forgot how to. It's around 1400 or so. But they will indeed resolve all pixels of a 720x1280 input.
Sony and Panasonic both made super high def tubes that would resolve full 1080x1920, but they're rare.
