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 ...
A VGA extender is an electronic device that increases the signal strength from a VGA port, most often from a computer. They are often used in schools, businesses, and homes when multiple monitors are being run off one VGA port, or if the cable between the monitor and the computer will be excessively long (often pictures appear blurry or have ...
An example of such a hybrid solution is the original VGA card, that used a 6845 in combination with an ASIC. That is why all current VGA based video systems still use the hardware registers that were provided by the 6845.
An analog standard once used by Sun Microsystems, SGI and IBM. DMS-59: A connector that provides a DVI or VGA output on a single connector. DE-9: The historical connector used by EGA and CGA graphics cards is a female nine-pin D-subminiature . The signal standard and pinout are backward-compatible with CGA, allowing EGA monitors to be used on ...
Since the analog pins are directly compatible with VGA signaling, passive adapters are simple and cheap to produce, providing a cost-effective solution to support VGA on DVI. The long flat pin on a DVI-I connector is wider than the same pin on a DVI-D connector, so even if the four analog pins were manually removed, it still wouldn't be ...
It is a technology used on motherboards made by ECS, intended to allow an existing AGP card to be used in a new motherboard instead of requiring a PCIe card to be obtained (since the introduction of PCIe graphics cards few motherboards provide AGP slots). An "AGP Express" slot is basically a PCI slot (with twice the electrical power) with an ...
However, high-end boards with integrated graphics processor (IGP) still used Intel GMA integrated graphics processors. The deal with Intel ended with the purchase of ATI by AMD in 2006, with Intel announcing SiS IGP chipset (D201GLY chipset, codenamed "Little Valley") for entry-level desktop platform, replacing the "Grand County" series chipsets.
While the VGA resolution was superseded in the personal computer market in the 1990s and the SEGA Dreamcast in 1998, [86] it became a popular resolution on mobile devices in the 2000s. [87] VGA is still the universal fallback troubleshooting mode in the case of trouble with graphic device drivers in operating systems.
