Iiteknoloji zokubonisa ezihambelanayo ezivela kwiNvidia kunye ne-AMD bezithengiswa kangangeminyaka embalwa ngoku kwaye zifumene udumo olukhulu kubadlali ngenxa yokukhethwa okukhulu kweemonitha ezineendlela ezininzi kunye nohlahlo lwabiwo-mali olwahlukeneyo.

Okokuqala ukufumana amandla ajikelezayokwiminyaka emi-5 eyadlulayo, besilandela kwaye sivavanya zombini i-AMD FreeSync kunye neNvidia G-Sync kunye neemonitha ezininzi ezipakisha zombini. Ezi mpawu zimbini bezikade zahlukile, kodwa emva kokouhlaziyo oluthilekwayeukutshintsha uphawu, izinto namhlanje zihambelane kakuhle. Nantsi ingcaciso entsha kuyo yonke into ekufuneka uyazi ukususela ngo-2021.

I-Skinny kwi-Adaptive Sync

I-FreeSync kunye ne-G-Sync zimizekelo yokuvumelanisa okuguqukayo okanye izinga lokuhlaziya eliguquguqukayo le-iimonithaI-VRR ithintela ukugungqa nokukrazula isikrini ngokulungelelanisa izinga lokuhlaziya lesikrini ukuya kwinqanaba lesakhelo somxholo okwisikrini.

Ngokwesiqhelo ungasebenzisa i-V-Sync ukutshixa amazinga esakhelo kwizinga lokuhlaziya lemonitha yakho, kodwa oko kwazisa ezinye iingxaki ngokulaxwa kokufaka kwaye kunokunciphisa ukusebenza. Kulapho ke izisombululo zamazinga okuhlaziya aguquguqukayo ezifana neFreeSync kunye neG-Sync zingena khona.

Iimonitha zeFreeSync zisebenzisa umgangatho weVESA Adaptive-Sync, kwaye iiGPU zanamhlanje ezivela kwiNvidia kunye ne-AMD zixhasa iimonitha zeFreeSync.

Iimonitha zeFreeSync Premium zongeza ezinye izinto ezimbalwa ezifana namazinga aphezulu okuhlaziya (i-120Hz nangaphezulu kwi-resolutions ye-1080p okanye ngaphezulu) kunye ne-low framerate compensation (LFC). I-FreeSync Premium Pro yongeza inkxaso ye-HDR kolo luhlu.

I-G-Sync isebenzisa imodyuli yeNvidia eyiyo endaweni yesikali esiqhelekileyo sesikrini kwaye inika ezinye iimpawu ezongezelelweyo ezifana ne-Ultra Low Motion Blur (ULMB) kunye ne-Low Framerate Compensation (LFC). Ngenxa yoko, yi-Nvidia GPU kuphela enokusebenzisa iimonitha ze-G-Sync.

Ekuqaleni kuka-2019 emva kokuba iNvidia iqalile ukuxhasa iimonitha zeFreeSync, yongeza amanqanaba ambalwa kwiimonitha zayo eziqinisekisiweyo zeG-Sync. Umzekelo, iG-SyncIimonitha zokugqibelauphawu lweImodyuli ye-HDRkunye nesithembiso sokulinganiswa okuphezulu kwee-nits, ngelixa ii-G-Sync Monitors eziqhelekileyo zibonisa kuphela i-adaptive sync. Kukwakho nee-G-Sync Compatible monitors, ezizii-FreeSync monitors ezibonwe yiNvidia "zifanelekile" ukuhlangabezana nemigangatho yazo ye-G-Sync.

Injongo esisiseko ye-G-Sync kunye ne-FreeSync kukunciphisa ukukrazulwa kwesikrini ngokusebenzisa i-adaptive sync okanye i-variable refresh rate. Ngokwenyani olu phawu lunceda isibonisi ukuba sitshintshe ireyithi yokuhlaziya yesikrini ngokusekelwe kwireyithi yefreyimu evezwa yi-GPU. Ngokuthelekisa la mazinga mabini, kunciphisa i-artifact ebonakala ngathi yi-screen riding.

Uphuculo luyabonakala kakhulu, nto leyo enika amazinga aphantsi efreyimu inqanaba lokuguda xa lithelekiswa neleIiFPS ezingama-60. Ngamazinga aphezulu okuhlaziya, inzuzo yokuvumelanisa okuguqukayo iyancitshiswa, nangona ubuchwepheshe busanceda ukususa ukukrazuka kwesikrini kunye nokugungqa okubangelwa kukuguquguquka kwesantya sefreyimu.

Ukukhetha Umahluko

Nangona inzuzo yamazinga okuhlaziya aguquguqukayo ifana kakhulu naleyo imigangatho mibini, inomahluko ambalwa ngaphandle kwaloo nto inye.

Enye inzuzo ye-G-Sync kukuba isoloko ilungisa i-monitor overdrive ngokukhawuleza ukunceda ukuphelisa i-ghosting. I-monitor nganye ye-G-Sync iza ne-Low Framerate Compensation (LFC), iqinisekisa ukuba nokuba i-framerate yehla, akuyi kubakho naziphi na iingxaki zomgangatho womfanekiso. Olu phawu lufumaneka kwi-FreeSync Premium kunye ne-Premium Pro monitors, kodwa alusoloko lufumaneka kwi-monitors ezine-FreeSync eqhelekileyo.

Ukongeza, i-G-Sync ibandakanya uphawu olubizwa ngokuba yi-Ultra Low Motion Blur (ULMB) olutshintsha isibane sangasemva xa luhambelana nesantya sokuhlaziya sesibonisi ukunciphisa ukufiphala kwentshukumo nokuphucula ukucaca kwiimeko ezihamba kakhulu. Olu phawu lusebenza ngamanani aphezulu okuhlaziya azinzileyo, ngesiqhelo kwi-85 Hz okanye ngaphezulu, nangona luza nokunciphisa ukukhanya okuncinci. Nangona kunjalo, olu phawu alunakusetyenziswa kunye ne-G-Sync.

Oko kuthetha ukuba abasebenzisi kufuneka bakhethe phakathi kwamazinga okuhlaziya aguquguqukayo ngaphandle kokugungqa nokukrazula, okanye ukucaca okuphezulu kunye nokufiphala kwentshukumo ephantsi. Silindele ukuba uninzi lwabantu lusebenzise i-G-Sync ukuze ikwazi ukuguda, ngelixaabathandi bezemidlalo ze-esportsiza kukhetha i-ULMB ngenxa yokusabela kwayo nokucaca kwayo endaweni yokukrazula.

Ekubeni iFreeSync isebenzisa izikali zesikrini eziqhelekileyo, iimonitha ezihambelanayo zihlala zineendlela ezininzi zokunxibelelana kunezinye ze-G-Sync, kubandakanya iiports ezininzi ze-HDMI kunye nezihlanganisi ezindala ezifana ne-DVI, nangona oko kungathethi ukuba ukuvumelanisa okuguqukayo kuya kusebenza kuzo zonke ezo zihlanganisi. Endaweni yoko, i-AMD inesici esizichazayo esibizwa ngokuba yiFreeSync phezu kwe-HDMI. Oku kuthetha ukuba ngokungafaniyo ne-G-Sync, iFreeSync iya kuvumela amazinga okuhlaziya aguquguqukayo nge-HDMI cables version 1.4 okanye ngaphezulu.

Nangona kunjalo, incoko yeHDMI kunye neDisplayPort ithatha inguqu eyahlukileyo kancinci xa uqala ukuxoxa ngeeTV, njengoko ezinye iiTV ezihambelana neG-Sync zinokusebenzisa olu phawu ngentambo yeHDMI.
