Emulation of computer monitor in a wide screen television

摘要

Method and apparatus for using a wide screen television receiver operating at 2fH as a VGA or SVGA monitor. The VGA or SVGA board in a computer is programmed to generate an RGB video signal representing a picture having fewer than a normal number of horizontal lines than a conventional VGA or SVGA picture having a 4:3 format display ratio, in order to define a picture having a wide format display ratio, for example 16:9. The separate synchronizing signals of the RGB video signal are converted to a form recognizable by the video display circuit of the wide screen television receiver.
