Ib qho hauv VGA hais txog "array" es "adapter" vim nws tau tsim los ntawm qhov pib mus ua ib qho kev ntaws tib qho los hloov lub Motorola 6845 thiab ntau ntawm kev sib tw logics. Master ISA yog ib qho ua ke ntawm chips. Qhov kev tsim no yog siv los ntawm yav dhau los MDA, CGA, thiab EGA. No feature ntawm VGA tso cai rau nws yooj yim rau hauv PC lub niam ntawv, yooj yim ntxiv video nco, oscillator thiab RAMDAC, nrog rau kev tso saib. IBM's PS / 2 computer series yog tsim los siv VGA ntawm lub niam ntawv.
Nta, feem ntau ntawm cov computers thiab cov khoom siv sab nraud yog txuas nrog lub tshuab analog VGA. Lub tshuab computer hauv internet ua rau cov duab cov duab thiab hloov mus rau hauv R, G, thiab B thawj cov cim tseg thiab cov kab ntawm digital / analog converters hauv daim card graphics. Daim teeb liab synchronization, qhov teeb liab yog xa mus rau cov khoom ntaus ntawv los ntawm kab ntawv. Rau analog zaub pab kiag li lawm, xws li analog CRT qhia, cov pib ntses yuav xa ncaj qha mus rau cov khoom sib txuas, uas tsav thiab tswj cov kinescopes los tsim cov duab. Rau LCD, DLP thiab lwm cov khoom siv digital, cov coj tus / A / D (Analog / Digital) hloov siab yuav tsum tau teeb tsa nyob rau hauv lub tshuab ntaus ntawv los hloov cov teeb liab analog rau hauv cov teeb meem digital. Tom qab D / A thiab A / D hloov, qee cov ntsiab lus duab yog poob lawm. Nws yog to taub tias VGA interface yog thov kom muaj CRT zaub, tab sis kev txuas ib lub tshuab ntaus ntawv xws li cov kua siv lead ua kua, cov duab poob thaum lub sij hawm hloov txheej txheem kuj me ntsis ntxig cov duab ntxim.
