Video BIOS is the BIOS of a graphics card in a (usually IBM PC-derived) computer. It initializes the graphics card at the computer's boot time. It also implements INT 10h interrupt and VESA BIOS Extensions (VBE) [ 1 ] [ 2 ] for basic text and videomode output before a specific video driver is loaded.
The display adapter uses a DE-15 connector, sometimes referred to as HD-15. MCGA is similar to VGA in that it had a 256-color mode (the 256-color mode in VGA was sometimes referred to as MCGA) and uses 15-pin analog connectors. The PS/2 chipset's limited abilities prevent EGA compatibility and high-resolution multi-color VGA display modes.
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 ...
Allows higher performance animation to provide for smooth animation for computer games and other high performance graphics programs. Super VGA virtual screens Allows software to set up virtual display resolutions , larger than the actual displayed resolution, and smoothly scroll or pan around the larger image.
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.
Windows 10 includes WDDM 2.0, which is designed to dramatically reduce workload on the kernel-mode driver for GPUs that support virtual memory addressing, [37] to allow multithreading parallelism in the user-mode driver and result in lower CPU utilization.
A compact VGA box for Dreamcast with 3D printed shell. The Dreamcast VGA Box is an accessory for the Dreamcast, a video game console produced by Sega, that allows it to output to a computer monitor or a high-definition television (HDTV) set through a VGA connector in 480p, otherwise known as progressive scan.
Mode X is a 320 × 240 256-color graphics display mode of the VGA graphics hardware for IBM PC compatibles. It was first publicized by Michael Abrash in his July 1991 column in Dr. Dobb's Journal and then in chapters 47-49 of Abrash's Graphics Programming Black Book. [1] The term "Mode X" was coined by Abrash.
