Ukadaulo wowonetsera wosinthika kuchokera ku Nvidia ndi AMD wakhala ukugulitsidwa kwa zaka zingapo tsopano ndipo watchuka kwambiri ndi osewera chifukwa cha ma monitor ambiri okhala ndi zosankha zambiri komanso bajeti zosiyanasiyana.

Choyamba chikuwonjezekaZaka 5 zapitazo, takhala tikutsatira ndi kuyesa AMD FreeSync ndi Nvidia G-Sync komanso ma monitor ambiri omwe ali ndi zonse ziwiri. Zinthu ziwirizi zinali zosiyana kwambiri, koma pambuyo pakezosintha zinandikusintha dzina, zinthu masiku ano zagwirizana bwino kwambiri. Nayi zosintha pa chilichonse chomwe muyenera kudziwa kuyambira mu 2021.

Kugwirizana kwa Skinny pa Adaptive

FreeSync ndi G-Sync ndi zitsanzo za adaptive sync kapena variable refresh rate yazowunikiraVRR imaletsa chibwibwi ndi kung'ambika kwa chinsalu posintha liwiro lokonzanso la chowunikiracho kuti chigwirizane ndi liwiro la chimango cha zomwe zili pazenera.

Kawirikawiri mungogwiritsa ntchito V-Sync kuti mutseke liwiro la chimango ku liwiro la refresh la monitor yanu, koma zimenezo zimayambitsa mavuto ena ndi kuchedwa kwa input ndipo zimatha kuchepetsa magwiridwe antchito. Apa ndi pomwe mayankho a refresh rates osiyanasiyana monga FreeSync ndi G-Sync amabwera.

Ma monitor a FreeSync amagwiritsa ntchito muyezo wa VESA Adaptive-Sync, ndipo ma GPU amakono ochokera ku Nvidia ndi AMD amathandizira ma monitor a FreeSync.

Ma monitor a FreeSync Premium amawonjezera zinthu zina monga kuchuluka kwa zotsitsimutsa (120Hz kapena kupitirira apo pa resolution ya 1080p kapena kupitirira apo) ndi low framerate compensation (LFC). FreeSync Premium Pro imawonjezera chithandizo cha HDR pamndandandawu.

G-Sync imagwiritsa ntchito gawo la Nvidia m'malo mwa choyezera chowonetsera chachizolowezi ndipo imapereka zinthu zina monga Ultra Low Motion Blur (ULMB) ndi Low Framerate Compensation (LFC). Zotsatira zake, ma GPU a Nvidia okha ndi omwe angagwiritse ntchito ma monitor a G-Sync.

Kumayambiriro kwa chaka cha 2019 Nvidia itayamba kuthandiza ma monitor a FreeSync, idawonjezera magawo angapo ku ma monitor ake ovomerezeka a G-Sync. Mwachitsanzo, G-SyncOyang'anira apamwamba kwambirimbali yaGawo la HDRndipo lonjezo la kuchuluka kwa ma nits, pomwe ma G-Sync Monitors wamba amakhala ndi adaptive sync yokha. Palinso ma G-Sync Compatible monitors, omwe ndi ma FreeSync monitors omwe Nvidia yawaona kuti ndi "oyenera" kukwaniritsa miyezo yawo ya G-Sync.

Cholinga chachikulu cha G-Sync ndi FreeSync ndikuchepetsa kung'ambika kwa sikirini kudzera mu adaptive sync kapena variable refresh rate. Kwenikweni, izi zimathandiza kuti chiwonetserocho chisinthe refresh rate ya monitor kutengera framerate yomwe GPU imayika. Mwa kufananiza milingo iwiriyi, imachepetsa mawonekedwe owoneka bwino otchedwa screen tearing.

Kusinthaku kukuonekera bwino, zomwe zimapangitsa kuti mafelemu azikhala osalala mofanana ndi60 FPSPakukweza kwambiri, ubwino wa adaptive sync umachepa, ngakhale kuti ukadaulowu umathandizabe kuchotsa kung'ambika kwa skrini ndi kugwedezeka komwe kumachitika chifukwa cha kusinthasintha kwa chiŵerengero cha chimango.

Kusankha Kusiyana

Ngakhale kuti phindu la mitengo yosinthira yotsitsimula ndi lofanana pakati pa miyezo iwiriyi, ili ndi kusiyana pang'ono kunja kwa chinthu chimodzicho.

Ubwino umodzi wa G-Sync ndikuti nthawi zonse imasintha monitor overdrive nthawi yomweyo kuti ithandize kuchotsa ghosting. G-Sync iliyonse imabwera ndi Low Framerate Compensation (LFC), kuonetsetsa kuti ngakhale framerate itatsika, sipadzakhala mavuto aliwonse okhudzana ndi khalidwe la chithunzi. Mbali iyi imapezeka pa FreeSync Premium ndi Premium Pro monitors, koma nthawi zambiri simapezeka pa monitors omwe ali ndi FreeSync wamba.

Kuphatikiza apo, G-Sync ili ndi mawonekedwe otchedwa Ultra Low Motion Blur (ULMB) omwe amasinthasintha kuwala kwa kumbuyo mogwirizana ndi liwiro lokonzanso la chiwonetserocho kuti achepetse kusokonekera kwa kayendedwe ndikuwongolera kumveka bwino pazochitika zoyenda kwambiri. Mbaliyi imagwira ntchito pa liwiro lokonzanso lokhazikika, nthawi zambiri pa 85 Hz kapena kupitirira apo, ngakhale imabwera ndi kuchepetsa kuwala pang'ono. Komabe, mawonekedwe awa sangagwiritsidwe ntchito limodzi ndi G-Sync.

Izi zikutanthauza kuti ogwiritsa ntchito ayenera kusankha pakati pa kusinthasintha kwa kutsitsimula popanda chibwibwi ndi kung'ambika, kapena kumveka bwino komanso kusayenda bwino. Tikuyembekezera kuti anthu ambiri azigwiritsa ntchito G-Sync kuti ikhale yosalala, pomweokonda masewera apa intanetiadzakonda ULMB chifukwa cha kuyankha kwake bwino komanso kumveka bwino m'malo mongong'amba.

Popeza FreeSync imagwiritsa ntchito ma scaler owonetsera wamba, ma monitor ogwirizana nthawi zambiri amakhala ndi njira zambiri zolumikizirana kuposa ma G-Sync ena, kuphatikiza ma HDMI ports angapo ndi zolumikizira zakale monga DVI, ngakhale sizitanthauza kuti sync yosinthika idzagwira ntchito pa zolumikizira zonsezo. M'malo mwake, AMD ili ndi mawonekedwe odzifotokozera okha otchedwa FreeSync pa HDMI. Izi zikutanthauza kuti mosiyana ndi G-Sync, FreeSync imalola mitengo yosinthika yotsitsimula kudzera mu ma cable a HDMI mtundu 1.4 kapena kupitirira apo.

Komabe, kukambirana kwa HDMI ndi DisplayPort kumakhala kosiyana pang'ono mukayamba kukambirana za ma TV, chifukwa ma TV ena ogwirizana ndi G-Sync amathanso kugwiritsa ntchito izi kudzera mu chingwe cha HDMI.
