The Intel® Q35 GMCH provides access to:
A progressive scan analog monitor
An SDVO monitor
2.4.6.1 Intel® Q35 SDVO Capabilities
A Serial Digital Video Output (SDVO) communications bus is multiplexed to eight of the
sixteen PCIe ports on the Intel® Q35. The SDVO interface provides 1.0 MHz point-to-point
connectivity between the Intel® Q35 and an SDVO device. The PCIE-Q350 supports a
single SDVO device on a compatible IEI backplane. The SDVO device is installed in the
PCIe x16 expansion slot and the SDVO function enabled by connecting a 3-pin SDVO
control connector on the PCIE-Q350 to a corresponding control connector on the IEI
backplane. The SDVO control connector on the PCIE-Q350 is shown in Figure 2-6 .
