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.
