Page 2: Introduction
Introduction Concerns over image quality, the near-complete replacement of the CRT by LCDs and other new display technologies, and growing concerns over content protection are prompting significant changes in display interface technology. Although PCs will likely continue to use the VGA interface in the short run, long-term, the future is moving to all-digital. - Page 3 convergence on a single digital interface standard for all such products, which would likely pull commercial users in the same direction. • LCDs already account for the majority of the PC monitor market, and have a rapidly-growing share of the TV market. No other display technology is expected to displace the LCD from its top position over this time period.

The VGA connector – named for the Video Graphics Array standard introduced by IBM for the original Personal Computer products in 1987 has been the most successful PC monitor interface to date in the computer industry. In use now for over 20 years, the VGA (also known as the 15HD connector, for15-pin high-density D- subminiature) remains the standard analog video interface of the PC industry, but is beginning to experience limitations. - Page 5 Figure 2 VGA Connector Pinout Table 1 VGA Connector Pinout Signal Red video Green video Blue video Unused (n.c.)

The Digital Visual Interface, or DVI, standard was published by the Digital Display Working Group (DDWG) in 1999. The DDWG was an ad-hoc consortium of seven PC-industry companies – HP, Compaq, Intel, IBM, NEC, Fujitsu, and Silicon Image (the developer of the Transition Minimized Differential Signaling or TMDS electrical interface on which the standard was based). - Page 7 Figure 5 Figure 4 DVI-D Receptacle Connector DVI-I Receptacle Connector Table 2 DVI Pinout Signal Signal TMDS Data 2- +5 VDC TMDS Data 2+ Ground/sync return TMDS Data 2/4 shield Hot plug detect (HPD) TMDS Data 4- TMDS Data 0- TMDS Data 4+ TMDS Data 0+ DDC clock (SCL)

HDMI After the DDWG failed to agree on a specification for a consumer version of the DVI specification, Silicon Image formed a new consortium to develop a digital interface specifically for the consumer TV market, this time with six leading CE companies. The result was the High Definition Multimedia Interface, or HDMI. - Page 10 Figure 7 HDMI Receptacle Pinout Table 4 HDMI Receptacle Pinout Signal Signal TMDS Data 2+ DDC/CEC ground TMDS Data 2 shield +5 VDC TMDS Data 2- Hot plug detect (HPD) TMDS Data 1+ TMDS Data 1 shield TMDS Data 1- TMDS Data 0+ TMDS Data 0 shield TMDS Data 0-...

DisplayPort In late 2005, another consortium of computer and display electronics manufacturers – HP, Dell, Philips, NVIDIA, ATI (now AMD), Samsung, and Genesis Microchip – brought a new digital display interface specification to the Video Electronics Standards Association as a proposed new standard. About a year later, VESA published the original DisplayPort standard. - Page 12 Figure 9 DisplayPort Connector Pinout NOTE: Top row (from left) - pins 1, 3, 5 ... 19; Bottom row - pins 2, 4, 6 ... 20 Table 5 DisplayPort Connector Pinout Source Sink Signal Source Sink Signal Lane 0+ Ground Ground Ground Lane 0-...
