RGB is also the term referring to a type of component video signal used in the video electronics industry. It consists of three signals—red, green, and blue—carried on three separate cables/pins. RGB signal formats are often based on modified versions of the RS-170 and RS-343 standards for monochrome video.
The new motherboard provided hardware shadowing of Text Screen 2, at no cost to CPU time, therefore not affecting the speed of software running. Although Alternate Display Mode remained an option in the CDA menu, the machine would automatically detect the presence of Text Screen 2 and enabled hardware shadowing of Text Screen 2 into bank 0xE0 ...
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.
When the image is to be sent to the display, the GPU sends its image through a video display controller to generate a video signal, which is then sent to a display interface such as HDMI, VGA, or DVI GPUs can be divided into discrete and integrated units, the former being an external unit and the latter of which is included within a CPU die.

A 15-pin VGA connector for a personal computer A 21-pin SCART or JP21 connector for a television. The various RGB (red, green, blue) analog component video standards (e.g., RGBS, RGBHV, RGsB) use no compression and impose no real limit on color depth or resolution, but require large bandwidth to carry the signal and contain a lot of redundant data since each channel typically includes much of ...
When data from the keyboard arrives, the controller raises an interrupt (a keyboard interrupt) to allow the CPU to handle the input. If a keyboard is a separate peripheral system unit (such as in most modern desktop computers ), the keyboard controller is not directly attached to the keys, but receives scancodes from a microcontroller embedded ...
A game port (not provided by recent super I/O chips because Windows XP is the last Windows OS to natively support game ports, requiring vendors to supply their own drivers for later Windows operating systems) [citation needed] A watchdog timer; A consumer IR receiver; A MIDI port; Some GPIO pins; Legacy Plug and Play or ACPI support for the ...
BIOS POST card for ISA bus BIOS POST card for PCI bus Professional BIOS POST card for PCI bus Two POST seven-segment displays integrated on a computer motherboard. The original IBM BIOS made POST diagnostic information available by outputting a number to I/O port 0x80 (a screen display was not possible with some failure modes). Both progress ...
