When each scan line (row) is completed, the electron guns are shut off and relocated to the beginning pixel of the following scan line. This horizontal movement is referred to as horizontal retrace. Electron guns are transferred to the first pixel of the first row after reaching the last pixel of the screen. Vertical retrace refers to the vertical movement of electron weapons.
