Also, a TV rasterscan is interlaced, while the raster scan in a computer CRT is almost always non-interlaced. In a CRT, the raster is slightly smaller than the full screen size of the monitor. Theheight and width of the raster can be adjusted, as can the horizontal andvertical position. Other parameters such as pincushioning, horizontal linearity, and vertical linearity can be adjusted in some CRT monitors.In an LCD, the raster (usually called a grid) is scanned differently than in a CRT; …
