Horizontal Blank refers to a part of the process of displaying images on a television screen.

Some graphics systems can count horizontal blanks and change how the display is generated during this blank time in the signal; this is called a raster effect. In video games, some methods of parallax scrolling use a raster effect to simulate depth.
