Thawj qhov peb yuav tsum tau tsim yog "Dab tsi yog qhov refresh npaum li cas?"Hmoov zoo nws tsis yog qhov nyuaj heev.Refresh tus nqi tsuas yog tus naj npawb ntawm lub sij hawm ib qho screen refreshes cov duab nws qhia ib ob.Koj tuaj yeem nkag siab qhov no los ntawm kev muab piv rau tus nqi sib tw hauv cov yeeb yaj kiab lossis kev ua si.Yog tias ib zaj duab xis raug tua ntawm 24 thav duab ib ob (raws li tus qauv xinesmas), ces cov ntsiab lus tsuas yog qhia 24 cov duab sib txawv hauv ib ob.Ib yam li ntawd, ib qho zaub nrog cov zaub tus nqi ntawm 60Hz qhia 60 "thav duab" ib ob.Nws tsis yog tiag tiag thav duab, vim hais tias cov zaub yuav refresh 60 zaug txhua thib ob txawm tias tsis yog ib qho kev hloov pixel, thiab cov zaub tsuas yog qhia cov khoom noj rau nws.Txawm li cas los xij, qhov piv txwv tseem yog ib txoj hauv kev yooj yim kom nkag siab lub ntsiab lus tseem ceeb tom qab refresh tus nqi.Qhov siab dua refresh npaum li cas txhais tau tias muaj peev xwm los tswj tus ncej siab dua.Tsuas yog nco ntsoov, cov zaub tsuas yog qhia qhov chaw pub rau nws, thiab yog li ntawd, tus nqi siab dua yuav tsis txhim kho koj qhov kev paub yog tias koj qhov kev hloov tshiab twb siab dua tus nqi ntawm koj qhov chaw.

Thaum koj txuas koj lub monitor mus rau GPU (Graphics Processing Unit / Graphics Card) tus saib yuav tso saib txawm tias GPU xa mus rau nws, ntawm tus ncej npaum li cas nws xa nws, ntawm lossis qis dua tus ncej siab tshaj plaws ntawm tus saib.Cov ncej nrawm dua tso cai rau txhua qhov kev taw qhia ua rau ntawm lub vijtsam zoo dua (Daim duab 1), nrog txo cov lus tsa suab plooj.Qhov no tseem ceeb heev thaum saib cov yeeb yaj kiab ceev ceev lossis ua si.
