sink (panels, monitor, and TVs). The PCH supports HDCP 1.4 for content protection
over wired displays (DVI and DisplayPort).
1.3.1.5 Analog Display (VGA)
The VGA port supports analog displays. The maximum supported resolution is 2048 x
1536 (QXGA) at a 75 Hz refresh rate. The VGA port is enabled for POST whenever a
monitor is attached, regardless of the DVI-D connector status.
1.3.1.6 Digital Visual Interface (DVI-D)
The DVI-D port supports only digital DVI displays. The maximum supported resolution
is 1920 x 1200 at 60 Hz refresh (WUXGA). The DVI-D port is compliant with the
DVI 1.0 specification.
1.3.1.7 Multiple Display Configurations
The following multiple display configuration modes are supported (with appropriate
driver software):
Single Display is a mode with one display port activated to display the output to
•
one display device.
®
• Intel Display Clone is a mode with up to three display ports activated to drive the
display content of same color depth setting but potentially different refresh rate
and resolution settings to all the active display devices connected.
• Extended Desktop is a mode with up to three display ports activated to drive the
content with potentially different color depth, refresh rate, and resolution settings
on each of the active display devices connected.
