Lub yees duab phab ntsa yog xav tau yog tias koj xav ua ib phab ntsa video.
Lub video phab ntsa controllers qee zaum hu ua video phab ntsa processor, itis ib lub cuab yeej uas faib ib daim duab rau hauv ib feem kom tso tawm rau ntawm tus kheej cov ntxaij vab tshaus.
Hardware-based controllers yog cov khoom siv hluav taws xob tsim rau lub hom phiaj tshwj xeeb. Lawv feem ntau yog tsim los ntawm array ntawm video processing chipsets thiab tsis muaj kev ua haujlwm. Qhov kom zoo dua ntawm kev siv lub hardware video phab ntsa maub los yog kev ua haujlwm siab thiab kev ntseeg siab. Qhov tsis zoo suav nrog tus nqi siab thiab tsis muaj kev hloov pauv.
