Think Centre users can now benefit from a convenient, low-cost method for connecting a DVI-D digital display monitor to the graphics controller of their Think Centre system. The Lenovo ADD2 DVI-D Monitor Connection Adapter (HDCP) lets you have two monitors connected in a multimonitor environment. This adapter installs into a PCI Express x 16 slot with an ADD2-compliant chipset. When the DVI-D Monitor Connection Adapter is installed, the systems VGA connector is available for a conventional VGA monitor so that both displays can be used simultaneously in a clone-mode or in an extended ("stretched") desktop configuration. The ADD2 DVI-D Monitor Connection Adapter (HDCP) also supports High-bandwidth Digital Content Protection (HDCP), which is a digital rights management to control the digital audio & video content as it travels across the Digital Visual Interface (DVI). HDCP helps to prevent transmission of non-encrypted high-definition content. The desktop system encrypts signals before they are sent out as digital signals. The encrypted signals then pass through the DVI-D (ADD2) Connection Adapter to an "HDCP-enabled" DVI monitor. The DVI monitor decodes the incoming signals. If the DVI monitor is not "HDCP-enabled, " the monitor cannot display the image.
