HDCP Function
HDCP function is supported on this motherboard. To use HDCP
function with this motherboard, you need to adopt the monitor that
supports HDCP function as well. Therefore, you can enjoy the
superior display quality with high-definition HDCP encryption
contents. Please refer to below instruction for more details about
HDCP function.
What is HDCP?
HDCP stands for High-Bandwidth Digital Content Protection, a
specification developed by Intel®for protecting digital entertainment
content that uses the DVI interface. HDCP is a copy protection
scheme to eliminate the possibility of intercepting digital data
midstream between the video source, or transmitter - such as a
computer, DVD player or set-top box - and the digital display, or
receiver - such as a monitor, television or projector. In other words,
HDCP specification is designed to protect the integrity of content as it
is being transmitted.
Products compatible with the HDCP scheme such as DVD players,
satellite and cable HDTV set-top-boxes, as well as few entertain-
ment PCs requires a secure connection to a compliant display. Due
to the increase in manufacturers employing HDCP in their equipment,
it is highly recommended that the HDTV or LCDmonitor you purchase
is compatible.
For Windows®7 / 7 64-bit / VistaTM / VistaTM 64-bit OS:
Right click the desktop, choose “Personalize”, and select the “Display
Settings” tab so that you can adjust the parameters of the multi-monitor
according to the steps below.
A. Click the number ”2” icon.
B. Click the items “This is my main monitor” and “Extend the desktop onto
this monitor”.
C. Click “OK” to save your change.
D. Repeat steps A through C for the display icon identified by the number
three and four.
6. Use Surround Display. Click and drag the display icons to positions representing
the physical setup of your monitors that you would like to use. The placement
of display icons determines how you move items from one monitor to another.
