1440X1080 is 4:3 aspect ratio in HD. It's how shows and the like dealt with widescreen. DVD's do this, for example. It's mainly came about to deal with NTSC and PAL formats, for CRT TV sets. Also, it was used on film. Film has a preset size limit.
No one was gonna redesign cameras for the widescreen format, invented in the 50's. So they made lenses that did the work. And they squished the image into the 4:3 frame. But it also reduces size. Which is where it comes in handy for games. Less processing power needed to render the screen. But it's also 1080p. Just the pixels are stretched with wise back out to 16:9. You lose sharpness in the process. This is where the res bitching comes in play.
Perfect example: Put your console into 480p. Run it in 16:9 mode. But put your TV into 4:3. The menu is sharper. Than put it back to 16:9. It loses its sharpness. The menu is orginally rendered in 4:3 squished aspect.
