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 ...
Mini-VGA connectors are proprietary and non-standard alternative video connectors that were used on some laptops and other computer systems in place of a standard VGA connector. Apple , [ 1 ] HP , [ 2 ] and Asus [ 3 ] each introduced separate connectors using the same moniker of "mini-VGA", but which are otherwise physically incompatible with ...
After having used VGA-based 3∶2 resolutions HVGA (480 × 320) and "Retina" DVGA (960 × 640) for several years in their iPhone and iPod products with a screen diagonal of 9 cm or 3.5 inches, Apple started using more exotic variants when they adopted the 16∶9 aspect ratio to provide a consistent pixel density across screen sizes: first 1136 ...
Mode 13h is something of a curiosity, because the VGA is a planar device from a hardware perspective, and not suited to chunky graphics operation. The VGA has 256 KiB of video memory consisting of 4 banks of 64 KiB, known as planes (or 'maps' in IBM's documentation). Planar memory arrangement splits the pixels horizontally into groups of four.
Ultima II, the first game in the game series to be ported to IBM PC, used CGA composite graphics. King's Quest I also offered 16-color graphics on the PC, PCjr and Tandy 1000, but provided a 'RGB mode' at the title screen which would utilize only the ordinary CGA graphics mode, limited to 4 colors. Examples of CGA games on RGBI and composite ...
Windows Camera is an image and video capture utility included with the most recent versions of Windows and its mobile counterpart. It has been around on Windows-based mobile devices since camera hardware was included on those devices and was introduced on Windows PCs with Windows 8, providing users for the first time a first-party built-in camera that could interact with webcam hardware.

Each screen character is represented by two bytes aligned as a 16-bit word accessible by the CPU in a single operation. The lower (or character) byte is the actual code point for the current character set, and the higher (or attribute) byte is a bit field used to select various video attributes such as color, blinking, character set, and so forth.
