Standard Svga Driver Windows 7' title='Standard Svga Driver Windows 7' />Video Graphics Array Wikipedia. Video Graphics Array VGA is the display hardware first introduced with the IBM PS2 line of computers in 1. Through widespread adoption, the term has also come to mean either an analog computer display standard, the 1. D subminiature. VGA connector, or the 6. VGA hardware. VGA was the last IBM graphics standard to which the majority of PC clone manufacturers conformed, making it the lowest common denominator that virtually all post 1. Standard Svga Driver Windows 7' title='Standard Svga Driver Windows 7' />PC graphics hardware can be expected to implement. It was officially followed by IBMs Extended Graphics Array XGA standard, but was effectively superseded by numerous slightly different extensions to VGA made by clone manufacturers, collectively known as Super VGA. Today, the VGA analog interface is used for high definition video, including resolutions of 1. While the transmission bandwidth of VGA is high enough to support even higher resolution playback, there can be picture quality degradation depending on cable quality and length. How discernible this degradation is depends on the individuals eyesight and the display, though it is more noticeable when switching to and from digital inputs like HDMI or DVI.

Standard graphics modeseditStandard graphics modes are The 6. RGB table, although the high resolution mode is most commonly familiar from its use with a fixed palette under Microsoft Windows. The other color modes defaulted to standard EGA or CGA compatible palettes including the ability for programs to redefine the 1. EGA palette from a master 6. VGA specific programming. Higher resolution and other display modeseditHigher resolution and other display modes are also achievable, even with standard cards and most standard monitors  on the whole, a typical VGA system can produce displays with any combination of 5. Hz refresh rate, or. Hz refresh rate. 51. Hz, and including e. Hz, and 2. 56 to 3. Hz refresh rate range, as well as horizontal widths below 2. For example, high resolution modes with square pixels are available at 7. Hz or 3. 604. 80 6. Hz, and thin pixels, 1. Hz refresh rate with e. Narrow modes such as 2. Standard text modeseditStandard text modes 8. MDA based applications. EGA compatible or 6. As with the pixel based graphics modes, additional text modes are technically possible as VGA resolution settings are notionally calculated from character grid dimensions with an overall maximum of about 1. One variant that is sometimes seen is 8. Hz mode for an additional 5 or 1. Technical detailseditCircuitry designedit. VGA compared to other standard resolutions. VGA is referred to as an Array instead of an adapter because it was implemented from the start as a single chip  an application specific integrated circuit ASIC which replaced both the Motorola 6. ISA boards of the MDA, CGA, and EGA. Its single chip implementation allowed the VGA to be placed directly on a PCs motherboard with a minimum of difficulty, since it only required video memory, timing crystals and an external RAMDAC. As a result, the first IBM PS2 models were equipped with VGA on the motherboard, in contrast to all of the family one IBM PC desktop models  the PC, PCXT, and PC AT  which required a display adapter installed in a slot in order to connect a monitor. SpecificationseditThe original VGA specifications are as follows supporting e. As well as the standard modes, VGA can be configured to emulate many of the modes of its predecessors EGA, CGA, and MDA, including their reduced global color palettes with particular pre set colors chosen from the VGA palette for text and 4 or 1. Compatibility is almost full at BIOS level, but even at register level, a very high value of compatibility is reached. VGA is not directly compatible with the special IBM PCjr or HGC video modes, despite having sufficient resolution, color, refresh rate and memory capabilities any emulation of these modes has to be performed in software instead.

Signal timingseditThe intended standard value for the horizontal frequency of VGA is exactly double the value used in the NTSC M video system, as this made it much easier to offer optional TV out solutions or external VGA to TV converter boxes at the time of VGAs development, a technique proposed by Zia Shlaimoun it is also at least nominally twice that of CGA, which itself used broadcast frequency monitors, essentially tunerless televisions with more direct signal inputs. The formula for the VGA horizontal frequency is thus 6. Hz 4. 50. 0 1. Hz 3. Hz, obtained in practice by the method common to all raster based computer graphics of using a particular crystal oscillator or PLL frequency for the pixel clock and deriving all other horizontal and vertical frequencies by integer division. In this case, a 2. In fact, CGA itself was further adrift as it could only scan 2. NTSCs interlaced nature, and the limited precision of quartz oscillators and their tendency to drift slightly with temperature and supply voltage means real cards will have slightly higher or lower frequencies whose variance vs the nominal figures can easily exceed the inherent mismatch. All derived VGA timings i. MHz crystals and, to a lesser extent, the nominal 3. Hz line rate can be varied widely by software that bypasses the VGA firmware interface and communicates directly with the VGA hardware, as many MS DOS based games did. However, only the standard modes, or modes that at least use almost exactly the same H sync and V sync timings as one of the standard modes, can be expected to work with the original late 1.

Third party multisync CRT monitors were usually much more flexible, and in combination with super EGA, VGA, and later SVGA graphics cards using extended modes, could display a much wider range of resolutions and refresh rates at wholly arbitrary sync frequencies and pixel clock rates within a particular lowerupper range, depending on model, typically encompassing a range spanning CGAs 1.
