Serial Digital Video Out

As of January 2007, Intel has not publicly documented an intent to promote SDVO as an industry standard, despite its potential applicability to any PCI express platform with an Integrated Graphics Processor (IGP), or the desirability from the consumer perspective that SDVO adaptor cards be compatible and freely interchangeable among all such systems.

In particular, Intel has established the website intellinuxgraphics.org to promote fully open sourced drivers supporting all video technologies embodied in their 9xx-series platform.

SDVO encoders can be integrated into the motherboard or placed on a PCI express card, allowing video connectors to be added or exchanged at low cost.

Older ADD cards were AGP-based and did not provide a standard interface, posing difficulties for driver development.

From the Intel Desktop board DG965RY Technical Product Specification, section 1.5.1.4 "Advanced Digital Display (ADD2/ADD2+) Card Support": The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a 200 MHz pixel clock to the PCI Express x16 connector.

When an ADD2/ADD2+ card is detected, the Intel GMA X3000 graphics controller is enabled and the PCI Express x16 connector is configured for SDVO mode.
