242 Chapter 10—Video and Audio On the VGA cable connector that plugs into your video adapter, pin 9 is often pinless. Pin 5 is used only for testing purposes, and pin 15 is rarely used (these are often pinless as well). To identify the type of monitor connected to the system, some manufacturers use the presence or absence of the monitor ID pins in various combinations. Digital Flat Panel Pinouts The Digital Flat Panel (DFP) is a Video Electronic Standards Association specification for digital video displays, especially LCD panels. It was adopted in February 1999, but it already has been superseded for most uses by the DVI standard, discussed in the next section. The DFP supports a maximum resolution of 1280×1024 and transmits only digital signals. The DFP connector has two rows of edge connectors. Table 10.8 provides the pinouts for DFP. DFP panels can be adapted to the newer DVI by the use of an adapter cable because both standards use the same TDMS PanelLink digital transfer protocol.

Many of the newest high-performance video cards feature either the DVI-D (digital only) or DVI-I (digital and analog) version of this connector. DVI can support either high-resolution (dual-link, which is above 1280×1024 resolution) or low-resolution (singlelink, which has a maximum of 1280×1024 resolution) displays. DVI connectors use three rows of square pins, with pin 14 (power) recessed. Dual-link displays use all the connectors shown in Table 10.9, whereas single-link displays omit some connectors. Video cards that have only a DVI-I connector usually come with a special video cable that can connect to either analog VGA or DVI digital display types. Table 10.9 lists the pin assignments used by both DVI-D and DVI-I connectors.

The Digital Flat Panel (DFP) is a Video Electronic St<strong>and</strong>ards<br />

superseded for most uses by the DVI st<strong>and</strong>ard, discussed in the<br />
next section. The DFP supports a maximum resolution of<br />
1280×1024 <strong>and</strong> transmits only digital signals. The DFP connector<br />
has two rows of edge connectors.<br />
Table 10.8 provides the pinouts for DFP. DFP panels can be adapted<br />
to the newer DVI by the use of an adapter cable because both st<strong>and</strong>ards<br />
