Old oscilloscopes (CRT type) needed beam blanking to get from A to B invisible (in fact "without leaving a trace"). CRT based TV's have the same (Horizontal blanking and vertical blanking). Hence these signals names on the VGA connector (original CRT based).

Modern (LCD) type displays can go from A to B directly (addressable pixel based). That is why there generally is no Z-input (blanking input) on modern scopes.
