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 ...
Being completely dependent on the NTSC encoding/decoding process, composite color artifacting is not available on an RGBI monitor, nor is it emulated by EGA, VGA or contemporary graphics adapters. The modern, games-centric PC emulator DOSBox supports a CGA mode, which can emulate a composite monitor's color artifacting. Both 640 × 200 ...
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.
The PS/2 chipset's limited abilities prevent EGA compatibility and high-resolution multi-color VGA display modes. The tenure of MCGA was brief; the PS/2 Model 25 and Model 30 were discontinued by 1992, and the only manufacturer to produce a clone of this display adapter was Epson , in the Equity Ie and PSE-30 , since the VGA standard introduced ...
The later VGA standard built on this by mapping each of the 64 colors in from a larger, customizable, palette of 256. Standard EGA monitors do not support use of the extended color palette in 200-line modes, because the monitor cannot distinguish between being connected to a CGA card or being connected to an EGA card outputting a 200-line mode.
The result was equivalent to VGA or even PGC—but with a wide palette—at a point simultaneous with the IBM launch of VGA. Later, larger monitors (15" and 16") allowed use of an SVGA-like binary-half-megapixel 832×624 resolution (at 75 Hz) that was eventually used as the default setting for the original, late-1990s iMac.
Accelerated Graphics Port (AGP) is a parallel expansion card standard, designed for attaching a video card to a computer system to assist in the acceleration of 3D computer graphics.
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.
