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.
Example of a klm digital I/O expansion card using a large square chip from PLX Technology to handle the PCI bus interface PCI expansion slot Altair 8800b from March 1976 with an 18-slot S-100 backplane which housed both the Intel 8080 mainboard and many expansion boards Rack of IBM Standard Modular System expansion cards in an IBM 1401 computer using a 16-pin gold plated edge connector first ...
The eXtended Graphics Array (usually called XGA) is a graphics card manufactured by IBM and introduced for the IBM PS/2 line of personal computers in 1990 as a successor to the 8514/A. It supports, among other modes, a display resolution of 1024 × 768 pixels with 256 colors at 43.5 Hz ( interlaced ), or 640 × 480 at 60 Hz ( non-interlaced ...
Super VGA (SVGA) is a broad term that covers a wide range of computer display standards that extended IBM's VGA specification. [ 1 ] When used as shorthand for a resolution, as VGA and XGA often are, SVGA refers to a resolution of 800 × 600.
While most modern graphics cards have support for dual monitors and can expand a desktop across three screens, 3D games were generally limited to a single monitor. The GXM uses the standard Extended Display Identification Data (EDID) structure to communicate its capabilities to the graphics card just as a monitor does. However, the GXM's ...
EGA-specific monitors used a dual-sync design which could switch from the 15.7 kHz of 200-line modes to 21.8 kHz for 350-line modes. [26] A non-IBM EGA card. Many EGA cards have DIP switches on the back of the card to select the monitor type. If CGA is selected, the card will operate in 200-line mode and use 8×8 characters in text mode. If EGA ...
The Hercules Graphics Card (HGC) is a computer graphics controller formerly made by Hercules Computer Technology, Inc. that combines IBM's text-only MDA display standard with a bitmapped graphics mode, also offering a parallel printer port. [1] [2] This allows the HGC to offer both high-quality text and graphics from a single card.
Extended Video Graphics Array (or EVGA) is a standard created by VESA in 1991 (VBE 1.2) [1] [2] [3] denoting a non-interlaced resolution of 1024x768 at a maximum of 70 Hz refresh rate.
