Video graphics adapters (Adaptadores gráficos)

Un adaptador gráfico es una tarjeta equipada con un generador de caracteres o gráficos y memoria de vídeo para su visualización en la pantalla. Un microprocesador explora la memoria de vídeo y convierte la información digital del ordenador en señales visualizables. Estas tarjetas cumplen distintas normas que determinan la naturaleza y calidad de la imagen.

VGA (Video Graphics Array). Introducida en 1987, fue la primera tarjeta analógica, mejorando la resolución del estándar EGA: 640 X 480 píxeles para gráficos, 720 x 400 píxeles para texto, y una paleta de color de 256 colores. También podía emular las tarjetas EGA y CGA.

Super VGA, diseñado por VESA en 1989, ofrece una resolución de 800 x 600 píxeles.

VGA Extendido, introducido por VESA en 1991, ofrece una resolución máxima de 1024 x 768 píxeles (modo no entrelazado) y una velocidad de refresco ligeramente superior a la tarjeta XGA 8514ª de IBM.

Los adaptadores gráficos de gama alta, introducidos durante los tres últimos años para estaciones de trabajo profesionales, ofrecen resoluciones máximas desde 1280 x 1024 hasta 1600 x 1280, frecuencias de línea horizontal de hasta 90 kHz, y anchos de banda de hasta 200 MHz.

VIS (Viewable Image Size) ((tamaño de imagen visualizable))

Dimensión real de la imagen en la pantalla, medida en diagonal. La especificación VIS de un monitor es siempre menor que el tamaño de su pantalla. Por ejemplo, el tamaño de imagen visualizable de un monitor de 17 pulgadas es de unas 16 pulgadas. Depende del tamaño de pantalla útil del tubo de imagen y de la abertura del marco frontal.
