Into yokuqala okudingeka siyithole ukuthi "Liyini ngempela izinga lokuvuselela?"Ngenhlanhla ayiyona inkimbinkimbi kakhulu.Izinga lokuvuselela limane nje linani lezikhathi isibonisi esiqabula ngaso isithombe esisibonisa ngomzuzwana.Ungakuqonda lokhu ngokukuqhathanisa nezinga lozimele kumafilimu noma imidlalo.Uma ifilimu ishuthwa kumafreyimu angu-24 ngomzuzwana (njengezinga lesinema), okuqukethwe komthombo kukhombisa kuphela izithombe ezihlukene ezingu-24 ngomzuzwana.Ngokufanayo, isibonisi esinesilinganiso sokubonisa esingu-60Hz sibonisa “ozimele” abangama-60 ngomzuzwana.Akubona ozimele ngempela, ngoba isibonisi sizovuselela izikhathi ezingu-60 umzuzwana ngamunye ngisho noma kungekho neyodwa iphikseli eshintshayo, futhi isibonisi sibonisa kuphela umthombo ophakelwe kuso.Kodwa-ke, isifaniso kuseyindlela elula yokuqonda umqondo oyinhloko ngemuva kwesilinganiso sokuvuselela.Izinga lokuvuselela eliphezulu ngakho-ke lisho amandla okuphatha izinga eliphezulu lozimele.Khumbula nje, ukuthi isibonisi sibonisa kuphela umthombo ophakelwe kuso, ngakho-ke, izinga eliphezulu lokuvuselela kungenzeka lingathuthukisi ulwazi lwakho uma izinga lakho lokuvuselela selivele liphezulu kunezinga lozimele lomthombo wakho.

Uma uxhuma imonitha yakho ku-GPU (Iyunithi Yokucubungula Imifanekiso/Ikhadi Lezithombe) imonitha izobonisa noma yini i-GPU eyithumela kuyo, nganoma isiphi isilinganiso sozimele esiyithumelayo, ngaphansi noma ngaphansi kwezinga eliphezulu lozimele lemonitha.Izilinganiso zozimele ezisheshayo zivumela noma yikuphi ukunyakaza ukuthi kwenziwe esikrinini ngokushelela kakhudlwana (Fig 1), ngokufiphala kokunyakaza okuncishisiwe.Lokhu kubaluleke kakhulu uma ubuka ividiyo esheshayo noma imidlalo.
