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.
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.
If bit 5 of CH is set, that often means "Hide cursor". So CX=2607h is an invisible cursor. Some video cards have 16 scan lines, 00h-0Fh. Some video cards don't use bit 5 of CH. With these, make Start>End (e.g. CX=0706h) Set cursor position AH=02h BH = Page Number, DH = Row, DL = Column Get cursor position and shape AH=03h BH = Page Number
Front and rear views of the TVM MD-3, a third-party EGA monitor. DE-9 input, mode switch, contrast and brightness controls at front, V size and V hold knobs at rear. Third-party monitors sometimes connected pin two to ground internally. When connected to an EGA card, this shorts the EGA's secondary red output to ground and can damage the card.
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 ...
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 ...
In computing, DirectInput is a legacy [1] Microsoft API for collecting input from a computer user, via input devices such as the mouse, keyboard, or a gamepad.It also provides a system for action mapping, which allows the user to assign specific actions within a game to the buttons and axes of the input devices.
