DDC1 and DDC2B/Ab/B+/Bi protocols are a physical link between a monitor and a video card, which was originally carried on either two or three pins in a 15-pin analog VGA connector. Extended display identification data (EDID) is a companion standard; it defines a compact binary file format describing the monitor's capabilities and supported ...
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 ...
Super VGA (SVGA) or Extended VGA is a broad term that covers a wide range of computer display standards that extended IBM's VGA specification. [ 1 ] [ 2 ] When used as shorthand for a resolution, as VGA and XGA often are, SVGA refers to a resolution of 800 × 600.
A VGA extender is an electronic device that increases the signal strength from a VGA port, most often from a computer. They are often used in schools, businesses, and homes when multiple monitors are being run off one VGA port, or if the cable between the monitor and the computer will be excessively long (often pictures appear blurry or have ...
Other common display modes also defined as VGA include 320×200 at 256 colours (8 bpp) (standard VGA resolution for DOS games that stems from halving the pixel rate of 640×400, but doubling color depth) and a text mode with 720×400 pixels; these modes run at 70 Hz and use non-square pixels, so 4:3 aspect correction is required for correct ...
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.
