Video Display Adapters
915
Most recent video cards with multiple-monitor support feature a 15-pin analog VGA connector for
CRTs, a DVI-I digital/analog connector for digital LCD panels, and a TV-out connector for S-video or
composite output to TVs and VCRs. Thus, you can connect any of the following to these cards:
■ One analog LCD or CRT display and one digital LCD
■ Two analog LCD or CRT displays (when the DVI-I–to–VGA adapter is used)
■ One analog LCD or CRT display and one TV
■ One digital LCD and one TV
The major video chipsets that support multiple CRT and LCD displays are listed in Table 15.18.
