Functional Description
5.26.4 Multiple Display Configurations
Microsoft Windows* XP, Windows Vista* and Windows* 7 operating systems supports
multiple displays. The PCH has two pipes which send the display data out through the
ports. Two display pipes enables the PCH to support two different images on different
display devices.
• Single Display is a mode with one display port activated to display the output to
one display device.
• Intel
®
Dual Display Clone is a mode with two display ports activated to display
the same output to two different display devices with the same color depth setting,
but potentially different refresh rates and resolution settings.
• Extended Desktop is a mode with two display ports activated used to display two
different outputs to two different display devices with potentially different color
depth, refresh rate, and resolution settings.
Table 5-61 describes the valid interoperability between display technologies.
5.26.5 High-bandwidth Digital Content Protection (HDCP)
HDCP is the technology for protecting high definition content against unauthorized copy
or unreceptive between a source (computer, digital set top boxes, etc.) and the sink
(panels, monitor, and TVs). The PCH supports HDCP 1.4 for content protection over
wired displays (HDMI, DVI, and DisplayPort).
The HDCP 1.4 keys are integrated into the PCH and customers are not required to
physically configure or handle the keys.
