Into yokuqala ekufuneka siyiqonde kukuba “Yintoni kanye kanye izinga lokuhlaziya?” Ngethamsanqa ayinzima kangako. Izinga lokuhlaziya linani nje lezihlandlo umboniso owuhlaziya ngazo umfanekiso owubonisayo ngomzuzwana. Ungakuqonda oku ngokuthelekisa izinga lesakhelo kwiifilimu okanye kwimidlalo. Ukuba ifilimu idutyulwa kwiifreyimu ezingama-24 ngomzuzwana (njengoko kunjalo ngomgangatho wesinema), ngoko umxholo womthombo ubonisa kuphela imifanekiso engama-24 eyahlukeneyo ngomzuzwana. Ngokufanayo, umboniso onezinga lokubonisa le-60Hz ubonisa “iifreyimu” ezingama-60 ngomzuzwana. Ayizizo iifreyimu ngokwenene, kuba umboniso uya kuhlaziya amaxesha angama-60 ngomzuzwana nokuba akukho pixel inye itshintshayo, kwaye umboniso ubonisa kuphela umthombo owunikwayo. Nangona kunjalo, ukufanisa kuseyindlela elula yokuqonda ingcamango engundoqo emva kwezinga lokuhlaziya. Izinga lokuhlaziya eliphezulu ke ngoko lithetha ukukwazi ukusingatha izinga lesakhelo eliphezulu. Khumbula nje ukuba umboniso ubonisa kuphela umthombo owunikwayo, kwaye ke ngoko, izinga lokuhlaziya eliphezulu lisenokungaphuculi amava akho ukuba izinga lakho lokuhlaziya sele liphezulu kunezinga lesakhelo lomthombo wakho.

Xa uqhagamshela isikrini sakho kwiGPU (iYunithi yokuCwangcisa iMifanekiso/iKhadi leMifanekiso) isikrini siya kubonisa nantoni na iGPU eyithumelayo kuso, nangaliphi na izinga lesakhelo eliyithumelayo, ngesantya sesakhelo esiphezulu okanye ngaphantsi kwesantya sesakhelo sesikrini. Amazinga esakhelo akhawulezayo avumela naluphi na ushukumo ukuba luboniswe kwisikrini ngokutyibilikayo ngakumbi (Umzobo 1), kunye nokufiphala kwentshukumo okuncitshisiweyo. Oku kubaluleke kakhulu xa ubukela ividiyo okanye imidlalo ekhawulezayo.
