Display Detection and Initialization
The Display Detection and Initialization feature, when enabled, automatically detects displays and allocates ports without the need to change any configuration files. This feature is off by default and can be enabled either through CED or by directly editing the iegd.inf file for Microsoft Windows or the xorg.conf file for the Linux OS.
To enable the feature via CED, select the DisplayDetect option on the CED Chipset Configuration page. Please see Creating a New Configuration.
Alternatively, you can enable the feature in Microsoft
Windows by entering the following line in the iegd.inf
section [iegd_SoftwareDeviceSettings_xxx]
(where xxx = chipset/processor code name, for example: tnc
for Atom E6xx, plb for US15W, etc.):
where <ConfigID> is the configuration ID (without the angle brackets).
To enable the feature in the Linux OS, enter the following line Option setting in the xorg.conf file:
When the display detection feature is enabled, ports are allocated only when the display satisfies the following conditions:
1. The port is not in use (that is, it is not already allocated).
2. The port driver detects the display.
The first port that passes these conditions is allocated. If condition 2 fails for all ports, then the first port in the PortOrder setting that passes condition 1 is allocated. If the port is not detectable (specifically the internal LVDS or external LVDS using CH7308), the driver assumes the display is connected. Condition number 2. always passes for these displays.
When this feature is disabled, display allocation is done based on PortOrder and no display detection is performed.
