Iyini izinga lokuvuselela?

Into yokuqala okudingeka siyiqonde ukuthi “Liyini ngempela izinga lokuvuselela?” Ngenhlanhla aliyinkimbinkimbi kakhulu. Izinga lokuvuselela limane nje linani lezikhathi isibonisi esivuselela ngazo isithombe esisibonisa ngomzuzwana. Ungakuqonda lokhu ngokuqhathanisa nezinga lohlaka kumafilimu noma imidlalo. Uma ifilimu idutshulwa kumafreyimu angu-24 ngomzuzwana (njengoba kunjalo ngendinganiso yesinema), khona-ke okuqukethwe komthombo kubonisa izithombe ezingu-24 ezihlukene ngomzuzwana kuphela. Ngokufanayo, isibonisi esinezinga lokubonisa elingu-60Hz sibonisa “ozimele” abangu-60 ngomzuzwana. Akuwona amafreyimu ngempela, ngoba isibonisi sizovuselela izikhathi ezingu-60 ngomzuzwana noma ngabe akukho pixel eyodwa eshintshayo, futhi isibonisi sibonisa kuphela umthombo onikezwe wona. Kodwa-ke, ukufaniswa kuseyindlela elula yokuqonda umqondo oyinhloko ngemuva kwesilinganiso sokuvuselela. Ngakho-ke izinga lokuvuselela eliphezulu lisho ikhono lokusingatha izinga lohlaka eliphezulu. Khumbula nje ukuthi isibonisi sibonisa kuphela umthombo onikezwe wona, ngakho-ke, izinga lokuvuselela eliphezulu lingase lingathuthukisi ulwazi lwakho uma izinga lakho lokuvuselela selivele liphakeme kunezinga lohlaka lomthombo wakho.

Kungani kubalulekile?

Uma uxhuma i-monitha yakho ku-GPU (Iyunithi Yokucubungula Izithombe/Ikhadi Lezithombe) i-monitha izobonisa noma yini i-GPU eyithumela kuyo, nganoma yisiphi isivinini sohlaka eyithumelayo, ngesilinganiso sohlaka esiphezulu se-monitha noma ngaphansi kwaso. Amazinga ohlaka asheshayo avumela noma yikuphi ukunyakaza ukuthi kwenziwe esikrinini ngokushelela kakhudlwana (Isithombe 1), ngokufiphala kokunyakaza okuncishisiwe. Lokhu kubaluleke kakhulu uma ubuka ividiyo noma imidlalo esheshayo.

Izinga Lokuvuselela kanye Nemidlalo

Yonke imidlalo yevidiyo yenziwa ngehadiwe yekhompyutha, kungakhathaliseki ukuthi iyiplatifomu noma ihluzo. Ngokuvamile (ikakhulukazi eplatifomu ye-PC), ozimele bakhishwa ngokushesha ngangokunokwenzeka, ngoba lokhu kuvame ukuhunyushwa kumdlalo obushelelezi nomnandi. Kuzoba nokulibaziseka okuncane phakathi kohlaka ngalunye futhi ngenxa yalokho kuzoba nokulibaziseka okuncane kokufaka.

Inkinga engenzeka ngezinye izikhathi yilapho ozimele bekhishwa ngokushesha kunesilinganiso lapho isibonisi sivuselela khona. Uma unesikrini esingu-60Hz, esisetshenziselwa ukudlala umdlalo okhipha ozimele abangu-75 ngomzuzwana, ungase uzwe into ebizwa ngokuthi “ukuklebhula kwesikrini”. Lokhu kwenzeka ngoba isibonisi, esamukela okokufaka okuvela ku-GPU ngezikhathi ezithile ezivamile, cishe sizobamba ihadiwe phakathi kozimele. Umphumela walokhu ukuklebhula kwesikrini kanye nokunyakaza okungalingani. Imidlalo eminingi ikuvumela ukuthi uklebhule izinga lozimele wakho, kodwa lokhu kusho ukuthi awusebenzisi i-PC yakho ngokugcwele. Kungani uchitha imali eningi kangaka ezingxenyeni zakamuva nezinkulu njenge-GPU nama-CPU, ama-RAM nama-SSD drive uma uzoklebhula amakhono awo?

Ungazibuza ukuthi iyini ikhambi lalokhu? Izinga lokuvuselela eliphezulu. Lokhu kusho ukuthi uthenga i-computer monitor engu-120Hz, 144Hz noma engu-165Hz. Lezi zikrini zingaphatha amafreyimu afinyelela ku-165 ngomzuzwana futhi umphumela uba umdlalo obushelelezi kakhulu. Ukuthuthukisa kusuka ku-60Hz kuya ku-120Hz, 144Hz noma ku-165Hz umehluko obonakalayo kakhulu. Kuyinto okumele uyibonele mathupha, futhi awukwazi ukwenza lokho ngokubuka ividiyo yayo kusikrini esingu-60Hz.

Izinga lokuvuselela eliguquguqukayo, nokho, ubuchwepheshe obusha obusezingeni eliphezulu obuqala ukuthandwa kakhulu. I-NVIDIA ibiza lokhu ngokuthi i-G-SYNC, kuyilapho i-AMD iyibiza ngokuthi i-FreeSync, kodwa umqondo oyinhloko uyafana. Isibonisi esine-G-SYNC sizobuza ikhadi lehluzo ukuthi liletha ngokushesha kangakanani ozimele, futhi silungise izinga lokuvuselela ngokufanele. Lokhu kuzoqeda ukudabuka kwesikrini kunoma yiliphi izinga lohlaka kuze kufike ezingeni eliphezulu lokuvuselela lesibonisi. I-G-SYNC ubuchwepheshe i-NVIDIA ekhokhisa imali ephezulu yelayisensi futhi ingangeza amakhulu amadola entengo yesibonisi. I-FreeSync ngakolunye uhlangothi ubuchwepheshe bomthombo ovulekile obunikezwa yi-AMD, futhi bunezela inani elincane kuphela ezindlekweni zesibonisi. Thina kwa-Perfect Display sifaka i-FreeSync kuzo zonke izikrini zethu zemidlalo njengejwayelekile.

Okushiwo Abadlali Begeyimu

Lapho bebuzwa ngamamonitha bonke abadlali abangochwepheshe bathi basebenzisa okungenani i-144Hz ekusethweni kwabo. Amandla okuvuselela isikrini ngokusheshisa okuphindwe kabili kunemonitha ejwayelekile avumela abadlali ukuthi basabele ngokushesha ezinguqukweni zomdlalo futhi kunciphisa ukufiphala kokunyakaza okungabangela ukuphazamiseka ngokuphambukisa izithombe eziboniswayo.

Uma bekhuluma ngesisombululo, bonke bathi izinga lokuvuselela elingu-144Hz (noma ngaphezulu) lingenye yezinto ezibalulekile lapho ukhetha i-gaming monitor. Esinye isici esibalulekile yisisombululo. Isixazululo esithandwa kakhulu phakathi kwabadlali begeyimu yi-1080p ngoba kulula ukuthola izinga eliphezulu lozimele ngakho-ke uzozuza ngesilinganiso sokuvuselela esiphezulu.

Uma uthenga i-monitor entsha yokudlala, kufanele ucabangele phambili futhi. Kufanele uhlose i-1440p uma unesabelomali sayo ngoba kuzoba utshalomali olungcono futhi usengathola amazinga aphezulu ozimele. Isixazululo se-1080p silungile uma usayizi wesikrini ungama-intshi angu-24. Ku-monitor engu-27-35 intshi, kufanele ukhethe i-1440p futhi kukho konke okungenhla, i-4K UHD iyindlela engcono kakhulu yokutshala imali.
