In the NTSC system, the maximum number of resolution lines is 525.
( A monitor of 700 lines would be overkill for us, ok in France, though ).
However, synchronization and other information occur in that dark band you
see when you turn vertical hold, called the blanking pulse(or some other
buzzword). This limits usable information to a maximum of 484 vertical lines.

HDTV is proposing to have something on the order of 1150 lines.
