VESA Digital Flat Panel

VESA Digital Flat Panel (DFP ) is an interface for digital transmission of video data should find use in TFT and LCD monitors.

In the DFP Group to PC manufacturers closed ( Compaq, Acer, Fujitsu, Siemens -Nixdorf ), graphics card manufacturer (ATI, S3, Matrox ) and monitor manufacturer ( Viewsonic, MAG Technology, Princeton, LG Electronics, Samsung, Lite -on, Compal Electronics, TECO information Systems) together. DFP is based on P & D and was standardized in February 1999 by the VESA, but could not prevail as opposed to later DVI. Only a few graphics cards and monitor models for DFP were produced.

Due to the all-digital transmission, quality advantages over the compound with a VGA or SCART cable. Since VGA and SCART cables carry an analog signal drop when connecting two flat screens unnecessary signal conversions at: from digital to analog and back to the video output from analog to digital in the monitor.

The DFP interface uses the so-called MDR connector ( mini -D ribbon ). There is a 20 -pin and 26- pin version of this connector. It can be due to a snap simply plugged and need not be screwed. Commonly used is the 20 - pin version, only it is listed in the VESA standard.

DFP uses, such as DVI also, the TMDS protocol for data transmission. DVI is backwards compatible with DFP, so can DFP monitors can be connected with an adapter to a DVI video cards, and vice versa. In the DFP resolution but 1024 pixels at a refresh rate of 60 Hz or 800 × 600 pixels is limited at a refresh rate of 85 Hz to 1280 ×. DFP uses dreikanaligem panel link with a bandwidth of 85 MHz and a maximum cable length of 5 m.

DFP supports the VESA DDC standard for device recognition and DPMS power management.
