P&D combined analog and digital video with data over USB and FireWire to reduce cable clutter, but the feature creep resulted in an unpopular, expensive connector.
[2]: 4 Compaq described DFP as a "transition" step between the analog VGA connector and P&D: DFP was designed by a consortium including Compaq, Hewlett-Packard, and ATI Technologies as a smaller, simpler connector, dropping support for analog video and data in favor of transmitting exclusively digital video signals.
It was offered on graphics cards such as the Xpert LCD,[3] and Rage LT Pro by ATI Technologies, and the Oxygen GVX1[4] by 3Dlabs.
[5]: §1.2 Like the preceding P&D, DFP uses the PanelLink TMDS protocol developed by Silicon Image for digital video signals.
All DFP-compliant devices are required to support resolutions of 640×400, 720×400, and 640×480 (each at a refresh rate of 60Hz) as a minimum level of interoperability, although the resulting display may not necessarily be centered or scaled.
