Yuav tsum muaj lub sijhawm teb pixel sai sai kom tshem tawm cov ghosting (qab) tom qab cov khoom txav ceev hauv kev ua si ceev ceev. Lub sijhawm teb ceev npaum li cas nyob ntawm qhov siab tshaj plaws ntawm lub monitor.

Piv txwv li, lub monitor 60Hz ua kom daim duab tshiab 60 zaug hauv ib ob (16.67 milliseconds ntawm kev ua kom tshiab). Yog li, yog tias ib lub pixel siv sijhawm ntev dua 16.67ms los hloov ntawm ib xim mus rau lwm xim ntawm 60Hz zaub, koj yuav pom ghosting tom qab cov khoom txav ceev.

Rau lub monitor 144Hz, lub sijhawm teb yuav tsum qis dua 6.94ms, rau lub monitor 240Hz, qis dua 4.16ms, thiab lwm yam.

Cov pixels siv sijhawm ntev dua los hloov ntawm dub mus rau dawb dua li lwm yam, yog li txawm tias txhua qhov kev hloov pauv pixel dawb mus rau dub qis dua 4ms hais ntawm lub monitor 144Hz, piv txwv li, qee qhov kev hloov pauv pixel tsaus mus rau lub teeb tseem yuav siv sijhawm ntau dua 10ms. Yog li ntawd, koj yuav pom cov xim dub smearing hauv cov xwm txheej ceev ceev nrog ntau cov pixels tsaus nti koom nrog, thaum nyob rau hauv lwm qhov xwm txheej, ghosting yuav tsis pom tseeb. Feem ntau, yog tias koj xav kom tsis txhob muaj ghosting, koj yuav tsum nrhiav cov monitors gaming nrog lub sijhawm teb ceev ntawm 1ms GtG (Gray rau Grey) - lossis qis dua. Qhov no, txawm li cas los xij, yuav tsis lav qhov ua tau zoo ntawm lub sijhawm teb, uas yuav tsum tau ua kom zoo los ntawm kev siv overdrive ntawm lub monitor.

Kev siv overdrive zoo yuav ua kom cov pixels hloov pauv sai txaus, tab sis nws kuj tseem yuav tiv thaiv kev rov qab ghosting (piv txwv li pixel overshoot). Inverse ghosting yog tus cwj pwm ua ib txoj kab ci ntsa iab ua raws li cov khoom txav mus los, uas yog tshwm sim los ntawm cov pixels raug thawb hnyav dhau los ntawm kev teeb tsa overdrive hnyav. Txhawm rau nrhiav seb qhov overdrive tau siv zoo npaum li cas ntawm lub monitor, nrog rau qhov chaw teeb tsa twg yuav tsum siv ntawm qhov refresh rate twg, koj yuav tsum nrhiav cov kev tshuaj xyuas ntxaws ntxaws ntawm lub monitor.
