Ithini izinga lokuhlaziya?

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.

Kutheni kubalulekile?

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.

Ireyithi yokuHlaziya kunye neMidlalo

Yonke imidlalo yevidiyo yenziwa ngezixhobo zekhompyutha, nokuba iqonga okanye imizobo injani. Ngokuyintloko (ingakumbi kwiqonga lePC), iifreyimu zikhutshwa ngokukhawuleza kangangoko zinokuveliswa, kuba oku kudla ngokuthetha ukuba umdlalo ulula kwaye umnandi. Kuya kubakho ukulibaziseka okuncinci phakathi kwefreyimu nganye kwaye ngaloo ndlela kubekho ukulibaziseka okuncinci kokufaka.

Ingxaki enokubakho ngamanye amaxesha kukuba iifreyimu zenziwa ngokukhawuleza kunesantya esihlaziya ngaso isibonisi. Ukuba unesikrini se-60Hz, esisetyenziselwa ukudlala umdlalo obonisa iifreyimu ezingama-75 ngomzuzwana, unokufumana into ebizwa ngokuba "kukukrazula kwesikrini". Oku kwenzeka kuba isibonisi, esamkela igalelo elivela kwi-GPU ngamaxesha athile aqhelekileyo, sinokubamba izixhobo zekhompyutha phakathi kweefreyimu. Isiphumo soku kukukrazula kwesikrini kunye nokunyakaza okungalinganiyo. Imidlalo emininzi ikuvumela ukuba unciphise izinga lefreyimu yakho, kodwa oku kuthetha ukuba awusebenzisi iPC yakho ngokupheleleyo. Kutheni uchitha imali eninzi kangaka kwizinto zamva nje nezibalaseleyo ezifana neeGPU kunye neeCPU, ii-RAM kunye nee-SSD drives ukuba uza kunciphisa amandla azo?

Usenokuzibuza ukuba yintoni isisombululo sale nto? Isantya sokuhlaziya esiphezulu. Oku kuthetha ukuba uthenge i-120Hz, 144Hz okanye i-165Hz computer monitor. Ezi displays zinokusingatha ukuya kuthi ga kwi-165 frames ngomzuzwana kwaye isiphumo siyindlela yokudlala ebushelelezi kakhulu. Ukuphucula ukusuka kwi-60Hz ukuya kwi-120Hz, 144Hz okanye kwi-165Hz ngumahluko obonakalayo kakhulu. Yinto ekufuneka uyibonele ngokwakho, kwaye awunakukwenza oko ngokubukela ividiyo yayo kwi-60Hz display.

Nangona kunjalo, izinga lokuhlaziya elihambelanayo yiteknoloji entsha ephucukileyo esiya ithandwa ngakumbi. I-NVIDIA ibiza le G-SYNC, ngelixa i-AMD iyibiza ngokuba yiFreeSync, kodwa ingcamango ephambili iyafana. Isibonisi esine-G-SYNC siya kubuza ikhadi lemizobo ukuba likhawuleza kangakanani na ukuhambisa iifreyimu, kwaye silungise izinga lokuhlaziya ngokufanelekileyo. Oku kuya kuphelisa ukukrazulwa kwesikrini nakweyiphi na inqanaba lesakhelo ukuya kuthi ga kwizinga eliphezulu lokuhlaziya lemonitha. I-G-SYNC yiteknoloji i-NVIDIA ehlawulisa umrhumo ophezulu welayisenisi kwaye inokongeza amakhulu eedola kwixabiso lemonitha. I-FreeSync kwelinye icala yiteknoloji evulelekileyo enikezelwa yi-AMD, kwaye yongeza imali encinci kuphela kwixabiso lemonitha. Thina kwi-Perfect Display sifaka i-FreeSync kuzo zonke iimonitha zethu zemidlalo njengesiqhelo.

Oko Kuthethwa Ngabadlali Bemidlalo

Xa bebuzwa ngeemonitha bonke abadlali abaziingcali bathi basebenzisa ubuncinci i-144Hz kwiisetingi zabo. Ukukwazi ukuba isikrini sihlaziyeke ngaphezu kwesibini ngokukhawuleza kunemonitha eqhelekileyo kuvumela abadlali ukuba basabele ngokukhawuleza kutshintsho kumdlalo kwaye kunciphisa ukufiphala kwentshukumo okunokubangela ukuphazamiseka ngokugqwetha imifanekiso eboniswayo.

Xa bethetha ngesisombululo, bonke bathi izinga lokuhlaziya le-144Hz (okanye ngaphezulu) yenye yezinto ezibalulekileyo xa ukhetha isixhobo sokubukela imidlalo. Enye into ebalulekileyo sisisombululo. Isisombululo esidumileyo phakathi kwabadlali yi-1080p kuba kulula ukufumana izinga eliphezulu lefreyimu ngaso kwaye ke ngoko uya kuzuza kwizinga eliphezulu lokuhlaziya.

Xa uthenga isixhobo esitsha sokubukela imidlalo, kufuneka ucinge phambili. Kufuneka ujonge i-1440p ukuba unayo imali eyaneleyo kuba iya kuba lutyalo-mali olungcono kwaye usenokufumana amaxabiso aphezulu efreyimu. Isisombululo se-1080p silungile ukuba ubungakanani besikrini buyi-24 intshi. Kwisixhobo sokubukela esiyi-27-35 intshi, kufuneka ukhethe i-1440p kwaye kuyo yonke into engasentla, i-4K UHD lolona tyalo-mali lubalaseleyo.
