Nov 16th 2006 12:28PM (Joystiq)As I understand it (and I'm sure someone will correct me if I'm wrong), it has to do with the number of scanlines and the accuracy of the gun.
When a TV draws a 1080i image, it's scanning two fields with 540 lines each. One field shows half the image, the other field shows the other half.
In order to draw a 720p image, the TV would have to scan one field with 720 lines. That means the scanlines are packed much closer together, and the gun would have to move much faster to draw the image on the screen.
Furthermore, a typical high definition broadcast displays an image at 60 frames per second. With a 1080i broadcast, the TV will typically only have to scan 60 540 line fields every second, and a 720p broadcast would require a 720 line field to be drawn 60 times per second.
