SVGA
Super VGA (SVGA) or Extended VGA is a broad term that covers a wide range of computer display standards that extended IBM's Video Graphics Array, VGA specification. When used as shorthand for a resolution, as VGA and XGA often are, SVGA refers to a resolution of 800 × 600. History In the late 1980s, after the release of IBM's VGA, third-party manufacturers began making graphics cards based on its specifications with extended capabilities. As these cards grew in popularity, they began to be referred to as "Super VGA". This term was not an official standard, but a shorthand for enhanced VGA cards which had become common by 1988. The first cards that explicitly used the term were Genoa Systems's SuperVGA and SuperVGA HiRes in 1987. Super VGA cards broke compatibility with the IBM VGA standard, requiring software developers to provide specific Display driver, display drivers and implementations for each card their software could operate on. Initially, the heavy restricti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Graphics Array
Video Graphics Array (VGA) is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, which became ubiquitous in the IBM PC compatible industry within three years. The term can now refer to the computer display standard, the 15-pin D-subminiature VGA connector, or the Graphics display resolution, resolution characteristic of the VGA hardware. VGA was the last IBM graphics standard to which the majority of IBM PC compatible computer manufacturers conformed, making it the Lowest common denominator#Colloquial usage, lowest common denominator that virtually all post-1990 PC graphics hardware can be expected to implement. VGA was adapted into many extended forms by third parties, collectively known as Super VGA, then gave way to custom graphics processing units which, in addition to their proprietary interfaces and capabilities, continue to implement common VGA graphics modes and interfaces to the presen ...

Computer Display Standard
Computer display standards are a combination of aspect ratio, display size, display resolution, color depth, and refresh rate. They are associated with specific expansion cards, video connectors, and monitors. History Various computer display standards or display modes have been used in the history of the personal computer. They are often a combination of aspect ratio (specified as width-to-height ratio), display resolution (specified as the width and height in pixels), color depth (measured in bits per pixel), and refresh rate (expressed in hertz). Associated with the screen resolution and refresh rate is a display adapter. Earlier display adapters were simple frame-buffers, but later display standards also specified a more extensive set of display functions and software controlled interface. Beyond display modes, the VESA industry organization has defined several standards related to power management and device identification, while ergonomics standards are set by th ...

Trident Microsystems
Trident Microsystems Inc. was an American fabless semiconductor company that became in the 1990s a well-known supplier of integrated circuits (commonly called "chips") for video display controllers used in video cards and on motherboards for desktop PCs and laptops. In 2003, it transformed itself into being a supplier of display processors for digital televisions, and primarily LCD TVs starting from 2005, at a time when the global LCD TV market started showing strong growth. It filed for bankruptcy protection in January 2012 and the delisting of its common stock from the NASDAQ stock market was announced shortly thereafter. History PC graphics Established in 1987, Trident gained a reputation for selling inexpensive (for the time) but slow SVGA components. Many OEMs built add-in-boards using Trident VGA chipsets. As the PC graphics market shifted from simple framebuffer displays (basic VGA color monitor and later multi-resolution SVGA output) to more advanced 2D hardwa ...

VGA Connector
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, as well as many monitors, projectors and HD television sets. Other connectors have been used to carry VGA-compatible signals, such as mini-VGA or BNC, but "''VGA connector''" typically refers to this design. Devices continue to be manufactured with VGA connectors, although newer digital interfaces such as DVI, HDMI and DisplayPort are increasingly displacing VGA, and many modern computers and other devices do not include it. Physical design The VGA connector is a three-row, 15-pin D-subminiature connector referred to variously as DE-15, HD-15 or commonly DB-15(HD). DE-15 is the accurate nomenclature under the proprietary D-sub specifications: an "E" size D-sub connector, with 15 pins in three rows. Predecessor and early variant The standard 15-pin VGA ...

VESA Local Bus
The VESA Local Bus (usually abbreviated to VL-Bus or VLB) is a short-lived expansion bus introduced during the i486 generation of x86 IBM-compatible personal computers. Created by VESA (Video Electronics Standards Association), the VESA Local Bus worked alongside the then-dominant ISA bus to provide a standardized high-speed conduit intended primarily to accelerate video (graphics) operations. VLB provides a standardized fast path that add-in (video) card makers could tap for greatly accelerated memory-mapped I/O and DMA, while still using the familiar ISA bus to handle basic device duties such as interrupts and port-mapped I/O. Some high-end 386DX motherboards also had a VL-Bus slot. Historical overview In the early 1990s, the I/O bandwidth of the prevailing ISA bus, 8.33 MB/s for standard 16 bit 8.33 MHz slots, had become a critical bottleneck to PC video and graphics performance. The need for faster graphics was driven by increased adoption of graphical user interf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Depth
Color depth, also known as bit depth, is either the number of bits used to indicate the color of a single pixel, or the number of bits used for each color component of a single pixel. When referring to a pixel, the concept can be defined as bits per pixel (bpp). When referring to a color component, the concept can be defined as bits per component, bits per channel, bits per color (all three abbreviated bpc), and also bits per pixel component, bits per color channel or bits per sample. Modern standards tend to use bits per component, but historical lower-depth systems used bits per pixel more often. Color depth is only one aspect of color representation, expressing the precision with which the amount of each primary can be expressed; the other aspect is how broad a range of colors can be expressed (the gamut). The definition of both color precision and gamut is accomplished with a color encoding specification which assigns a digital code value to a location in a color space. The ...

Its first product, announced September 1985, was a four chip Enhanced Graphics Adapter, EGA chipset that handled the functions of 19 of IBM's proprietary chips on the Enhanced Graphics Adapter. By that November's COMDEX, more than a half dozen companies had introduced EGA-compatible boards based on C&T's chipset.The Enhanced Graphics Standard Comes of Age ''PC Magazine'', August 1986 This was followed by chipsets for PC motherboards and other computer graphics chips. C&T was acquired by Intel in 1997, primarily for its graphics chip business. Former members of C&T founded Asiliant Technologies in January 2000 to continue the supp ...

Orchid Technology
Orchid Technology was a privately held company founded by Le Nhon Bui in 1982. History 1982 to 1984 The company's original flagship product was its PCNet card, a 1 megabit-per-second LAN (networking) card for IBM PCs and clones. Notably, the acronym LAN (Local Area Networking) is the Vietnamese word for "Orchid". Hence, the origin of the company name. Also in 1982, it introduced the Orchid Graphics Adapter, a graphics board for IBM PC compatible computers. It was intended to provide high resolution (at the time) monochrome graphic abilities to computers limited to text displays. It was aimed at the business market and one of the three first third party graphic boards for PCs. After this successful product, the company embarked on introducing high-performance add-in cards, most notably the LIM ( Lotus, Intel Microsoft standard) which extended DOS out to 1M, Multi-purpose network cards that included RAM, clock, serial printer ports and Network COAX TCP-IP capabilities.
