PCI-E SLI-ready

PCI-E PC video card?s that are SLI-ready are those that support dual video interfaces: multiple monitors and video interconnections. These are one of two advisable options, and the only muiti-vendor option for HDTV offices: emergency operations centre?, council chamber?,war room, media production? use. And likely also for other emergency response facilities that may need to move video and audio fast to arbitrary desktops or briefing monitors.

These cards require one PCI-E? slot on a PC motherboard? but to use SLI requires two. At present only the ASUS A8N-SLI(external link) has the two slots required. It supports the K8 939 CPU from AMD?. As of 2005-09, no Intel? SLI option is available.

The main advantages of PCI-E SLI-ready cards are:
  • they are extremely fast, capable of doing desktop video?
  • they avoid the complexities of AGP? video card interfaces which exist in many speeds and even three different incompatible voltages
  • as of 2005-09?, all current cards of this kind(external link) support DVI and TV-out? ports.
    • Many also support S-video? and some also HDTV?.

Two Dual DVI cards can support up to four DVI outputs. This runs up to four large screens at very high resolution. It is quite suitable for use in a war room when major news breaks. Most GeForce cards in this class are dual DVI.

Some software such as ATI EAZYSHARE? lets video cards share the signal directly without using the computer itself. As of 2005-09 this is not yet available on any PCI-E SLI-ready cards but may be when the PCI-E ATI All-in-Wonder Pro(external link) is available in an SLI-ready version.

Until then, one box with the ATI PCI-E? card on a network using only ATI chips or cards is the only way to get an HDTV? signal onto a number of machines over a Gigabit LAN? in one physical office.

SLI will not duplicate all the advantages of an ATI solution but is a multi-source standard that does not rely on ATI as sole vendor?.
