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.
Ingabe kufanele ngithenge i-G-Sync ne-FreeSync ehambisanayo isibonisi semidlalo?
Ngokuvamile, i-Freesync ibaluleke kakhulu emidlalweni, hhayi nje ekugwemeni ukudabula kodwa nasekuqinisekiseni isipiliyoni esibushelelezi. Lokhu kuyiqiniso ikakhulukazi uma usebenzisa ihadiwe yokudlala ekhipha ozimele abaningi kunalokho isibonisi sakho esingakuthwala.
I-G-Sync kanye ne-FreeSync ziyizixazululo zazo zombili lezi zinkinga ngokuba nokuvuselelwa kwesibonisi ngesivinini esifanayo njengoba ozimele benziwa yikhadi lehluzo, okuholela ekudlaleni okubushelelezi, okungenazo izinyembezi.
Kuyini i-HDR?
Izibonisi zebanga eliphakeme elinamandla (i-HDR) zidala ukugqama okujulile ngokukhiqiza ububanzi obuphezulu bokukhanya okunamandla. Isikrini se-HDR singenza izici ezivelele zibukeke zikhanya futhi zilethe izithunzi ezicebile. Ukuthuthukisa i-PC yakho ngesikrini se-HDR kuyafaneleka uma udlala imidlalo yevidiyo enezithombe ezisezingeni eliphezulu noma ubuka amavidiyo ngesisombululo se-HD.
Ngaphandle kokungena ngokujulile emininingwaneni yobuchwepheshe, isibonisi se-HDR sikhiqiza ukukhanya okukhulu nokujula kombala kunezikrini ezakhiwe ukuhlangabezana nezindinganiso ezindala.
1MSIsikhathi Sokuphendulakunciphisa ukufiphala nokungacaci ngenkathi kuguqulwa amaphikseli, kugcina isitha nendawo kugxile ngqo ngezikhathi zesiphithiphithi.
Ukukhishwa kombala we-10 Bitingamela phakathi kuka-00000000000 kuya ku-111111111 kumbala ngamunye obomvu, oluhlaza okwesibhakabhaka, nophuzi, okusho ukuthi umuntu angamela imibala engu-64x ye-8-bit. Lokhu kungaphinda kukhiqize imibala engu-1024x1024x1024 = 1,073,741,824, okuyinani elikhulu kakhulu lemibala kune-8 bit. Ngenxa yalesi sizathu, ama-gradients amaningi esithombeni azobukeka ebushelelezi njengasesithombeni esingenhla, futhi izithombe ze-10 bit zibukeka zingcono kakhulu kunezinye ze-8-bit.
