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.
Video in video out (usually seen as the acronym VIVO), commonly pronounced (/ ˈ v i. v oʊ / VEE-voh), is a graphics port which enables some video cards to have bidirectional (input and output) analog video transfer through a mini-DIN connector, usually of the 9-pin variety, and a specialised splitter cable (which can sometimes also transfer analog audio).
On Linux and DOS systems with so-named SVGA cards, a program called SVGATextMode [34] can be used to set up better looking text modes than EGA and VGA standard ones. This is particularly useful for large (≥ 17") monitors, where the normal 80×25 VGA text mode's 720×400 pixel resolution is far lower than a typical graphics mode would be.
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 ...
A modern consumer graphics card: A Radeon RX 6900 XT from AMD. A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.
When the EGA card was first sold in 1984, the Video BIOS was introduced to make these cards compatible with existing PCs whose BIOS did not know how to drive an EGA card. Ever since, EGA/VGA and all enhanced VGA compatible cards have included a Video BIOS. When the computer is started, some graphics cards (usually certain Nvidia cards) display ...
Assembled Project VGA graphics board Open Graphics Project prototype. Project VGA aims to create a low-budget, open-source VGA-compatible video card. [104] The Open Graphics Project aims to create an open-hardware GPU. The Open Graphics Device v1 has dual DVI-I outputs and a 100-pin IDC connector.
VBE is made available through the video card's BIOS, which installs some interrupt vectors that point to itself during boot up. Most newer cards implement the more capable VBE 3.0 standard. Older versions of VBE provide only a real mode interface, which cannot be used without a significant performance penalty from within protected mode ...
