Cov yam ntxwv ntawm G-Sync
Feem ntau cov saib xyuas G-Sync muaj tus nqi siab dua vim tias lawv muaj cov khoom siv kho vajtse ntxiv uas xav tau los txhawb Nvidia qhov kev hloov kho tshiab. Thaum G-Sync tseem tshiab (Nvidia tau qhia nws hauv xyoo 2013), nws yuav raug nqi koj li $ 200 ntxiv rau kev yuav G-Sync version ntawm lub vijtsam, tag nrho lwm yam nta thiab cov yam ntxwv zoo ib yam. Niaj hnub no, qhov sib txawv ze li $ 100.
Txawm li cas los xij, FreeSync cov saib kuj tuaj yeem tau ntawv pov thawj tias yog G-Sync Compatible. Daim ntawv pov thawj tuaj yeem tshwm sim rov qab, thiab nws txhais tau tias lub saib tuaj yeem khiav G-Sync hauv Nvidia cov kev cai, txawm tias tsis muaj Nvidia cov khoom siv scaler tshwj xeeb. Kev mus saib Nvidia lub vev xaib qhia txog daim ntawv teev npe ntawm cov saib uas tau ntawv pov thawj kom khiav G-Sync. Koj tuaj yeem khiav G-Sync ntawm lub saib uas tsis yog G-Sync Compatible-certified, tab sis kev ua tau zoo tsis tau lees paub.

Muaj ob peb qhov kev lees paub uas koj tau txais nrog G-Sync cov saib uas tsis tas li muaj nyob rau hauv lawv cov FreeSync counterparts. Ib qho yog blur-reduction (ULMB) nyob rau hauv daim ntawv ntawm lub backlight strobe. ULMB yog Nvidia lub npe rau qhov feature no; qee cov FreeSync saib kuj muaj nws nyob rau hauv lub npe sib txawv. Txawm hais tias qhov no ua haujlwm hloov Adaptive-Sync, qee tus nyiam nws, pom tias nws muaj qis dua input lag. Peb tsis tau muaj peev xwm ua pov thawj qhov no hauv kev sim. Txawm li cas los xij, thaum koj khiav ntawm 100 thav duab ib ob (fps) lossis siab dua, blur feem ntau tsis yog teeb meem thiab input lag yog super-low, yog li koj yuav zoo li khaws cov khoom nruj nrog G-Sync koom nrog.

G-Sync kuj lav tias koj yuav tsis pom ib qho kev tawg ntawm tus ncej txawm tias nyob rau ntawm qhov qis tshaj plaws ntawm refresh rates. Hauv qab 30 Hz, G-Sync cov saib xyuas ob npaug ntawm cov ncej renders (thiab yog li ntawd ob npaug ntawm refresh rate) kom lawv khiav hauv qhov ntau yam adaptive refresh.

Cov yam ntxwv ntawm FreeSync
FreeSync muaj tus nqi zoo dua li G-Sync vim nws siv tus qauv qhib uas tsim los ntawm VESA, Adaptive-Sync, uas kuj yog ib feem ntawm VESA's DisplayPort spec.
Txhua lub DisplayPort interface version 1.2a lossis siab dua tuaj yeem txhawb nqa qhov hloov kho refresh rates. Txawm hais tias tus neeg tsim khoom yuav xaiv tsis siv nws, cov khoom siv twb muaj lawm, yog li ntawd, tsis muaj nqi tsim khoom ntxiv rau tus neeg tsim khoom los siv FreeSync. FreeSync kuj tseem tuaj yeem ua haujlwm nrog HDMI 1.4. (Yog xav pab nkag siab txog qhov twg zoo tshaj plaws rau kev ua si, saib peb qhov kev tshuaj xyuas DisplayPort vs. HDMI.)

Vim nws qhov qhib dav, kev siv FreeSync sib txawv ntawm cov monitors. Cov zaub pheej yig feem ntau yuav tau txais FreeSync thiab 60 Hz lossis ntau dua refresh rate. Cov zaub pheej yig tshaj plaws yuav tsis tau txais kev txo qhov tsis meej, thiab qhov txwv qis dua ntawm Adaptive-Sync ntau yam yuav tsuas yog 48 Hz. Txawm li cas los xij, muaj FreeSync (nrog rau G-Sync) cov zaub uas ua haujlwm ntawm 30 Hz lossis, raws li AMD, txawm tias qis dua.

Tab sis FreeSync Adaptive-Sync ua haujlwm zoo ib yam li txhua lub G-Sync monitor. Cov monitors FreeSync kim dua ntxiv kev txo qhov tsis meej thiab Low Framerate Compensation (LFC) kom sib tw zoo dua nrog lawv cov G-Sync counterparts.

Thiab, dua, koj tuaj yeem tau txais G-Sync khiav ntawm FreeSync monitor yam tsis muaj daim ntawv pov thawj Nvidia, tab sis kev ua tau zoo yuav poob qis.
