Daim npav video yog qhov tseem ceeb tshaj plaws ntawm kev siv computer ntiag tug niaj hnub no. Nws yog cov khoom siv no uas yog lub luag haujlwm los ua cov thev xaib video thiab xa nws mus rau ntau cov khoom siv tawm: ntsuas saib lossis lwm yam khoom siv coj los ua.
Muaj ntau lub laj thawj tseem ceeb rau daim npav qeeb daim npav. Qee lub sij hawm qhov no yog vim nws muaj peev xwm siv tshuab, thiab hauv lwm rooj plaub - kom muaj teeb meem kho tshuab nrog lub cuab yeej. Ntau zaus, muaj xwm txheej tshwm sim thaum daim npav video tsuas yog tsis cuam tshuam nrog cov haujlwm. Qhov no tuaj yeem tshwm sim los ntawm kev xa tawm ntawm ib daim ntawv thov lossis kev ua si, qhov system cov cai ntawm uas ntau tshaj qhov muaj peev xwm ntawm lub adapter video tau siv. Feem ntau cov teeb meem no daws tau los ntawm kev hloov cov tsis sib haum ntawm daim npav video los yog teeb tsa ib daim ntawv thov tshwj xeeb. Thaum nws los txog rau kev ua si, nws raug nquahu kom qis qhov zoo ntawm cov duab daim duab. Qhov no ua rau cov haujlwm ntawm qhov video adapter tau yooj yim. Qee zaum vim li cas rau qhov tshwm sim qeeb ntawm daim npav video tuaj yeem yog qhov nce hauv nws qhov kub siab tshaj qhov cim pom zoo. Tshaj dhau ntawm qhov video adapter tuaj yeem tshwm sim rau peb qhov laj thawj: - kev ua haujlwm tsis zoo ntawm lub kiv cua ntsia ntawm lub cuab yeej; qhaj los sis tsis zoo ntawm lub thermal paste nyob nruab nrab ntawm daim npav video chipset thiab lub tshuab ua kom txias txias Txhim kho thiab siv cov tsav tsis ncaj ncees kuj tseem tuaj yeem ua rau lub tshuab video tsis zoo. Heev tsis tu ncua, txhim kho cov ntawv pom zoo tshaj tawm tshiab ntawm cov software pab txhawb cov kev ua haujlwm ntawm daim npav video. Nws raug nquahu kom rub cov tsav tsheb rau feem ntau cov khoom siv los ntawm cov tuam ntxhab cov vev xaib. Thaum nws los ntawm lub computer mobile, qhov laj thawj rau qhov tshwm sim qeeb ntawm daim npav video tuaj yeem yog qhov teeb meem tsis raug xa hluav taws xob. Hauv qee qhov kev hloov kho, cov hloov kho video ua haujlwm ntawm 20-30% ntawm lawv lub zog ntau tshaj. Qhov no ua rau muaj qhov tseeb tias qee yam kev siv tsis ua haujlwm tsis raug thiab muaj cov teebmeem braking.
