PortOrder Information

PortOrder specifies the actual ports that are used for the Primary and Secondary display. As shown in the table below, the port numbers are slightly different among the supported chipsets.

Table 31. PortOrder Information

The driver attempts to use the ports in the order specified by “PortOrder”. For example, “PortOrder” = “42000” will assign the internal LVDS port to the primary display and the SDVO port to the secondary display (if any), assuming all the ports are present and detected. Suppose port “4” is not present, in that case the driver tries to assign the next port (2, in this case) in line to the primary display, resulting in SDVO port for primary.

Setting PortOrder to “00000” causes the driver to use default internal settings.

; PortOrder specifies the actual port

; that will be taken for the Primary /

; Secondary ports if there are duplicates

; of the same type. For example, if both

; Primary and Secondary are digital, then

; port order will determine which sDVO ports

; will be first and second. The section below

; gives the port order numbers for various chipsets.

; Specify value “0000” to use default settings.

; 1 - Integrated TV Encoder

; 2 - sDVO B port/RGBA port

; 3 - sDVO C port

; 4 - Internal LVDS port

; 5 - Analog port
