The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [1] as well as many monitors, projectors and HD television sets.
VGA section on the motherboard in IBM PS/55. The color palette random access memory (RAM) and its corresponding digital-to-analog converter (DAC) were integrated into one chip (the RAMDAC) and the cathode-ray tube controller was integrated into a main VGA chip, which eliminated several other chips in previous graphics adapters, so VGA only additionally required external video RAM and timing ...
VGA connector (DE-15) Became a nearly ubiquitous analog computer display connector after first being introduced with IBM x86 machines. Older VGA connectors were DE-9 (9-pin). The modern DE-15 connector can carry Display Data Channel to allow the monitor to communicate with the graphics card, and optionally vice versa. [10]
The Enhanced Graphics Adapter (EGA) is an IBM PC graphics adapter [2] [3] and de facto computer display standard from 1984 that superseded the CGA standard introduced with the original IBM PC, and was itself superseded by the VGA standard in 1987.
Professional Graphics Controller (PGC, often called Professional Graphics Adapter and sometimes Professional Graphics Array) is a graphics card manufactured by IBM for PCs. [1] It consists of three interconnected PCBs , and contains its own processor and memory.
The 13W3 connector can be converted into a standard VGA connector or DVI-A using commonly available cables and adapters. This allows multisync monitors, which became prevalent in personal computing in the late 1980s, to be used with these workstations as long as they are sync-on-green compatible. Likewise, later-generation Sun monitors, which ...
Back of a CGA Video Adapter board, with the RCA composite output connector visible on the right. The Color Graphics Adapter uses a standard RCA connector for connection to an NTSC-compatible television or composite video monitor. [3] The connector on the card is female and the one on the monitor cable is male.
IBM 8514 is a graphics card manufactured by IBM and introduced with the IBM PS/2 line of personal computers in 1987. It supports a display resolution of 1024 × 768 pixels with 256 colors at 43.5 Hz ( interlaced ), or 640 × 480 at 60 Hz ( non-interlaced ).
