Intel Desktop Board DQ87PG Technical Product Specification 1.3.1.3 Integrated Audio Provided by the DisplayPort Interface The DisplayPort interface from the PCH supports audio. The processor supports two High Definition audio streams on two digital ports simultaneously. Table 4 shows the specific audio technologies supported by the PCH. Table 4. Audio Formats Supported by the DisplayPort Interface Audio Formats AC-3 - Dolby* Digital Dolby Digital Plus DTS-HD* LPCM, 192 kHz/24 bit, 8 Channel Dolby TrueHD, DTS-HD Master Audio* (Lossless Blu-ray Disc Audio Format) DisplayPort Yes Yes Yes Yes Yes 1.3.1.4 High-bandwidth Digital Content Protection (HDCP) HDCP is the technology for protecting high definition content against unauthorized copy or interception 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 (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. 18
