Video grafikkort

Ett kort utrustat med en tecken- eller grafikgenerator och videominne, som avbildar (mappar) skärmen. En mikroprocessor avsöker videominnet och översätter bit-informationen från datorn till visningsbara videosignaler för monitorn. Dessa kort uppfyller kraven i olika standarder som bestämmer typen och kvaliteten på displayen.

VGA (Video Graphics Array), introducerades 1987, och var det första analoga kortet. Det gav ännu högre upplösning än EGA: 640 X 480 pixels för grafik och 720 x 400 pixels för text, och en färgpalett med 256 färger. VGA kunde även emulera (efeterlikna) EGA och CGA.

Super VGA, uppfunnet av VESA år 1989, ger en upplösning på 800 x 600 pixels.

Extended VGA, introducerades av VESA år 1991, och ger en maximal upplösning på 1024 x 768 pixels (non-interlaced) och en uppdateringshastighet något högre än IBM's XGA 8514A.

High-end, grafikkort, introducerades under de tre senaste åren för professionella arbetsstationer, och ger maxupplösningar från 1280 x 1024 till 1600 x 1280, horisontell linjefrekvens upp till 90 kHz och bandbredder upp till 200 MHz.

VIS (Viewable Image Size)

Det verkliga skärmmått som användaren kan se mäts diagonalt. VIS för en monitor är alltid mindre än den så kallade skärmstorleken på en monitor. Till exempel så är VIS för en 17-tums monitor bara ca. 16 tum. Det beror på den användbara skärmytan på bildröret och öppningen i monitorns frontkabinett.
