Abstract
A computer-generated image signal is analyzed to derive a set of alignment parameters for a television. These alignment parameters arc then used to configure the television accordingly. The alignment parameters may include aspects of the computer-generated image signal such as a vertical period, a horizontal frequency, a horizontal front porch, a horizontal active image time and/or a maximum RGB video level. The television may be configured to reduce its raster length to accommodate the compute generated image signal. Further, the values of the horizontal measurements for the active video time, front porch and frequency of the computer-generated image signals may be used to determine values for the television's horizontal picture size and position. Such values may be determined by computation or by table look up. In addition, other television alignment parameters such as upper and lower pin cushion, vertical bow, pin amplitude and/or horizontal angle may be determined. The RGB parameters of the computer generated image signal may be used to derive optimal brightness and/or contrast settings for the television.
