Abstract:
1. A display apparatus for displaying an input video signal having one of a plurality of specifications, the apparatus comprising: a format converter which inputs the video signal having one of various specifications, converts the video signal into a converted video signal having a converted horizontal frequency and outputs the video signal having the converted horizontal frequency; a driver which drives a display unit using the converted video signal; and a deflection driver which generates a deflection signal appropriate for a video signal having converted formats based on the converted horizontal frequency and the vertical frequency of the converted video signal and supplies the deflection signal to the display unit; wherein the format converter is adapted to convert as the input video signal, a normal TV signal, a DTV signal, or a PC signal into the converted video signal having a converted horizontal frequency of approximately 48 KHz; and wherein in the format converter, the normal TV signal and the HDTV signal are changed to have a vertical frequency of 75 Hz and 576 effective scanning lines, while the PC signal is changed to a format of an extended graphic array (XGA, 1024×768/60 Hz) mode.
