Cov thev naus laus zis adaptive sync display los ntawm Nvidia thiab AMD tau nyob rau hauv kev ua lag luam rau ob peb xyoos tam sim no thiab tau txais ntau qhov nrov nrog cov neeg ua si ua tsaug rau kev xaiv ntau ntawm cov saib nrog ntau txoj kev xaiv thiab ntau yam peev nyiaj.

Thawj zaug tau txais kev txhawb zog nyob ib puag ncig5 xyoo dhau los, peb tau ua raws li thiab sim ob qho tib si AMD FreeSync thiab Nvidia G-Sync thiab ntau lub monitors uas muaj ob qho tib si. Ob qho yam ntxwv tau siv los sib txawv heev, tab sis tom qabqee qhov hloov tshiabthiabkev hloov pauv lub npe, tej yam niaj hnub no tau sib phim ob qho zoo nkauj heev. Nov yog qhov hloov tshiab ntawm txhua yam koj yuav tsum paub txog xyoo 2021.

Tus Skinny ntawm Adaptive Sync

FreeSync thiab G-Sync yog cov piv txwv ntawm kev hloov kho sync lossis hloov pauv refresh rate raucov saib xyuas. VRR tiv thaiv kev hais lus tsis meej thiab kev tawg ntawm qhov screen los ntawm kev kho qhov refresh rate ntawm lub monitor rau qhov frame rate ntawm cov ntsiab lus ntawm qhov screen.

Feem ntau koj tsuas yog siv tau V-Sync los xauv cov ncej rau koj lub monitor's refresh rates, tab sis qhov ntawd ua rau muaj qee qhov teeb meem nrog input lag thiab tuaj yeem ua rau kev ua haujlwm qeeb. Qhov ntawd yog qhov uas cov kev daws teeb meem hloov pauv refresh rates xws li FreeSync thiab G-Sync tuaj rau hauv.

Cov saib xyuas FreeSync siv tus qauv VESA Adaptive-Sync, thiab cov GPU niaj hnub los ntawm Nvidia thiab AMD txhawb nqa FreeSync saib xyuas.

Cov saib xyuas FreeSync Premium ntxiv ob peb yam ntxiv xws li cov nqi refresh siab dua (120Hz lossis ntau dua ntawm qhov kev daws teeb meem ntawm 1080p lossis siab dua) thiab kev them nyiaj rau tus nqi qis (LFC). FreeSync Premium Pro ntxiv kev txhawb nqa HDR rau daim ntawv teev npe ntawd.

G-Sync siv lub Nvidia module tshwj xeeb hloov chaw ntawm lub scaler zaub ib txwm muaj thiab muaj ob peb yam ntxiv xws li Ultra Low Motion Blur (ULMB) thiab Low Framerate Compensation (LFC). Yog li ntawd, tsuas yog Nvidia GPUs thiaj li siv tau G-Sync monitors.

Thaum ntxov xyoo 2019 tom qab Nvidia pib txhawb nqa FreeSync cov saib, nws tau ntxiv ob peb theem rau nws cov saib uas tau ntawv pov thawj G-Sync. Piv txwv li, G-SyncCov saib xyuas kawgfeature ibHDR Modulethiab cov lus cog tseg ntawm qhov ntsuas nits siab dua, thaum cov G-Sync Monitors ib txwm muaj tsuas yog muaj qhov sib dhos ua ke. Kuj tseem muaj G-Sync Compatible monitors, uas yog FreeSync monitors uas Nvidia tau suav tias "tsim nyog" ua tau raws li lawv cov qauv G-Sync.

Lub hom phiaj tseem ceeb ntawm G-Sync thiab FreeSync yog kom txo qhov kev tawg ntawm qhov screen los ntawm kev hloov kho sync lossis hloov pauv refresh rate. Qhov tseem ceeb, qhov feature no qhia rau lub screen kom hloov qhov refresh rate ntawm lub monitor raws li tus framerate uas GPU tso tawm. Los ntawm kev sib phim ob tus nqi no, nws txo qhov kev puas tsuaj uas hu ua kev tawg ntawm qhov screen.

Qhov kev txhim kho no pom tseeb heev, muab cov nqi qis dua ib qib ntawm kev du thiab sib npaug nrog60 FPSThaum muaj qhov refresh rates siab dua, qhov txiaj ntsig ntawm adaptive sync yuav txo qis, txawm hais tias cov thev naus laus zis tseem pab tshem tawm qhov screen tearing thiab stutters uas tshwm sim los ntawm kev hloov pauv ntawm tus ncej.

Xaiv Qhov Sib Txawv

Txawm hais tias qhov txiaj ntsig ntawm cov nqi hloov pauv hloov pauv yog ntau dua lossis tsawg dua tib yam ntawm ob tus qauv, lawv muaj ob peb qhov sib txawv sab nraud ntawm qhov feature ntawd.

Ib qho zoo ntawm G-Sync yog tias nws pheej kho qhov overdrive ntawm lub monitor kom pab tshem tawm ghosting. Txhua lub monitor G-Sync muaj Low Framerate Compensation (LFC), kom ntseeg tau tias txawm tias thaum tus framerate poob qis, yuav tsis muaj teeb meem dab tsi lossis teeb meem zoo ntawm daim duab. Qhov feature no pom muaj nyob rau ntawm FreeSync Premium thiab Premium Pro monitors, tab sis tsis pom ib txwm muaj nyob rau ntawm cov monitors uas muaj FreeSync tus qauv.

Tsis tas li ntawd xwb, G-Sync muaj ib qho feature hu ua Ultra Low Motion Blur (ULMB) uas ua rau lub backlight ci ntsa iab sib xws nrog lub refresh rate ntawm qhov screen kom txo qhov motion blur thiab txhim kho qhov meej meej hauv cov xwm txheej uas muaj kev txav siab. Qhov feature no ua haujlwm ntawm qhov refresh rate siab, feem ntau ntawm lossis siab dua 85 Hz, txawm hais tias nws muaj qhov txo qis me ntsis. Txawm li cas los xij, qhov feature no siv tsis tau nrog G-Sync.

Qhov ntawd txhais tau tias cov neeg siv yuav tsum xaiv ntawm cov nqi hloov pauv yam tsis muaj kev co thiab kua muag, lossis qhov meej siab thiab tsis muaj kev txav mus los. Peb xav tias feem ntau cov neeg siv G-Sync rau qhov du thiab yooj yim uas nws muab, thaumcov neeg nyiam esportsyuav nyiam ULMB rau nws qhov kev teb tau zoo thiab meej ntawm tus nqi ntawm kev rhuav tshem.

Vim tias FreeSync siv cov qauv tso saib scalers, cov monitors sib xws feem ntau muaj ntau txoj kev xaiv txuas ntau dua li lawv cov G-Sync counterparts, suav nrog ntau lub HDMI ports thiab legacy connectors xws li DVI, txawm hais tias qhov ntawd tsis tas li txhais tau tias adaptive sync yuav ua haujlwm hla tag nrho cov connectors ntawd. Hloov chaw, AMD muaj qhov feature self-piav qhia hu ua FreeSync hla HDMI. Qhov no txhais tau tias tsis zoo li G-Sync, FreeSync yuav tso cai rau cov nqi hloov pauv los ntawm HDMI cables version 1.4 lossis siab dua.

Txawm li cas los xij, kev sib tham ntawm HDMI thiab DisplayPort yuav siv sijhawm sib txawv me ntsis thaum koj pib tham txog TVs, vim tias qee lub TVs uas siv tau nrog G-Sync kuj tseem tuaj yeem siv qhov feature no los ntawm HDMI cable.
