Graphic Card Pin Configurations

CGA/EGA

CGA - 320 x 200, 15.7 kHz, 60 Hz
EGA - 640 x 350, 15.7/21.8 kHz, 60 Hz


pin 1 - Gnd pin 4 - Green pin 7 - Blue Int
pin 2 - Gnd/Red Int pin 5 - Blue pin 8 - H. Sync
pin 3 - Red pin 6 - Green Int pin 9 - V. Sync

CGA/EGA uses a digital signal, referred to as TTL (Transistor-Transistor Logic), for the transmission of its video signal. TTL is a signal that operates in an on or off state only, thus limiting the amount of displayable colors. Intensity bits are used to expand available colors up to four times the original amount. Commonly used in low resolution computers.
Signal Type: TTL

ECL

Sun & Apollo Mono (Black & White Workstations)


pin 1 - ECL Video pin 4 - V Sync pin 7- ECL Video Ret
pin 2 - ECL Video Ret pin 5 - 5 Volts pin 8 - Sync Return
pin 3 - H Sync pin 6 - ECL Video pin 9 - 5V Return

ECL (Emitter Coupled Logic) uses a high speed digital signal. It is commonly found in high to extremely high resolution computers where the displays are generally monochrome.
Signal type: ECL

Use of analog video signals allows for unlimited colors to be produced. Macintosh graphic cards are unique in a couple of different regards. First, the variety of sync formats. In the past, sync has been available three different ways, and in some cases all from one card. Those formats are RGsB, RGBS, and RGBHV. Macintosh graphic cards also offer multiple line rates and resolutions. These rates and resolutions are determined at boot up by the manner in which the sense lines (ID Bits) are terminated within the local monitor.
Signal Type: analog

Mac 12"- 512 x 384 24.5 kHz, 60 Hz

IBM developed XGA/XGA-2 (Extended Graphics Array) to provide a means to offer higher frequencies and resolutions in the "VGA" domain. These standards utilize software and ID bit termination to achieve these changes.

VGA/XGA 1- 640 x 350 31.5 kHz, 70 Hz
VGA/XGA 2- 640 x 400 31.5 kHz, 70 Hz
VGA/XGA 3- 640 x 480 31.5 kHz, 60 Hz
VGA/XGA 4- 1024 x 768 35.5 kHz, 87/43 Hz (Interlaced)
VGA/XGA 5- 1024 x 768 57.0 kHz, 70 Hz

Custom VGA* Up to 1600 x 1200 31-117 kHz, 60-110 Hz

*Many graphic card manufacturers offer super high resolution modes that are not necessarily a standard (like XGA or VESA). Thus, a customer running one of these non-standard modes can be displaying a graphics resolution up to 1600 x 1200 at 117 kHz (horizontal).

VESA is a standards committee that was adopted in 1988 to create a better standard than IBM's VGA version. VESA has offered more variety in video resolutions and it is still adopting more standards each year. To date, VESA has adopted standards that rang from standard VGA (at 640 x 480) to super high resolution graphics (1600 x 1200 at 106 kHz). Most VESA graphics cards are capable of switching resolutions "on-the-fly" if you are using Windows 95®, 98®, 2000® or through the set-up menu if you're using Windows® 3.1.

The EVC connector is a combination analog and digital connector designed to carry VGA/RGB, FireWire, audio, and USB signals. The EVC connector is essentially the same as the DVI connector, except it carries different signals. It was designed to simplify computer-monitor connections and to carry video signals with a greater bandwidth that is possible with a VGA connector.

DVI was developed by the Digital Display Working Group (DDWG). It carries the same type of signal as the DFP connector; however, the connector is not the same physically or in terms of pin out. The DVI connector comes in two forms, as DVI-D (Digital), a 24-pin version, or as a DVI-I (Integrated) 29-pin version. The 29-pin version allows an analog signal to also be carried.
