Zinthu za G-Sync
Ma monitor a G-Sync nthawi zambiri amakhala ndi mtengo wapamwamba chifukwa amakhala ndi zida zowonjezera zomwe zimafunikira kuti zithandizire mtundu wa Nvidia wa adaptive refresh. Pamene G-Sync inali yatsopano (Nvidia idayambitsa mu 2013), zimakuwonongerani ndalama zokwana $200 kuti mugule mtundu wa G-Sync wa chiwonetsero, zinthu zina zonse ndi mawonekedwe ake ndi zomwezo. Masiku ano, kusiyana kuli pafupi ndi $100.
Komabe, ma monitor a FreeSync akhozanso kutsimikiziridwa kuti ndi G-Sync Compatible. Chitsimikizochi chingachitike mobwerezabwereza, ndipo zikutanthauza kuti monitor ikhoza kuyendetsa G-Sync mkati mwa magawo a Nvidia, ngakhale kuti ilibe zida zoyezera za Nvidia. Kupita patsamba la Nvidia kukuwonetsa mndandanda wa ma monitor omwe atsimikiziridwa kuti ayendetsa G-Sync. Mutha kuyendetsa G-Sync pa monitor yomwe si G-Sync Compatible, koma magwiridwe antchito sakutsimikizika.

Pali zitsimikizo zingapo zomwe mumapeza ndi ma monitor a G-Sync omwe nthawi zambiri sapezeka mu ma FreeSync. Chimodzi ndi blur-reduction (ULMB) mu mawonekedwe a backlight strobe. ULMB ndi dzina la Nvidia la izi; ma monitor ena a FreeSync ali ndi dzina lina. Ngakhale izi zimagwira ntchito m'malo mwa Adaptive-Sync, ena amakonda, poganiza kuti zimakhala ndi kuchedwa kochepa kwa input. Sitinathe kutsimikizira izi poyesa. Komabe, mukathamanga pa mafelemu 100 pa sekondi (fps) kapena kupitirira apo, kulephera kwa blur nthawi zambiri si vuto ndipo kuchedwa kwa input kumakhala kochepa kwambiri, kotero mutha kusunga zinthu molimbika ndi G-Sync yomwe ikugwira ntchito.

G-Sync imatsimikiziranso kuti simudzawona chimango chikung'ambika ngakhale pamlingo wotsika kwambiri wotsitsimutsa. Pansi pa 30 Hz, G-Sync imayang'anira kawiri mawonekedwe a chimango (ndipo motero imachulukitsa kawiri kuchuluka kwa zotsitsimutsa) kuti zigwire ntchito mu adaptive refresh range.

Zinthu za FreeSync
FreeSync ili ndi phindu pamtengo poyerekeza ndi G-Sync chifukwa imagwiritsa ntchito muyezo wotseguka wopangidwa ndi VESA, Adaptive-Sync, womwenso ndi gawo la VESA's DisplayPort spec.
Mtundu uliwonse wa DisplayPort interface 1.2a kapena kupitirira apo ukhoza kuthandizira kusinthasintha kwa zosintha. Ngakhale wopanga angasankhe kusagwiritsa ntchito, zida zake zilipo kale, motero, palibe ndalama zina zopangira kuti wopanga agwiritse ntchito FreeSync. FreeSync ingagwirenso ntchito ndi HDMI 1.4. (Kuti mumvetse bwino zomwe zili bwino pamasewera, onani kusanthula kwathu kwa DisplayPort vs. HDMI.)

Chifukwa cha kutseguka kwake, kugwiritsa ntchito FreeSync kumasiyana kwambiri pakati pa ma monitor. Ma display otsika mtengo nthawi zambiri amakhala ndi FreeSync ndi refresh rate ya 60 Hz kapena kuposerapo. Ma display otsika mtengo kwambiri mwina sangachepetse blur, ndipo malire otsika a Adaptive-Sync angakhale 48 Hz yokha. Komabe, pali ma display a FreeSync (komanso G-Sync) omwe amagwira ntchito pa 30 Hz kapena, malinga ndi AMD, otsika kwambiri.

Koma FreeSync Adaptive-Sync imagwira ntchito bwino ngati chowunikira chilichonse cha G-Sync. Zowunikira za FreeSync zokwera mtengo zimawonjezera kuchepetsa kusokonekera kwa mawonekedwe ndi Low Framerate Compensation (LFC) kuti zipikisane bwino ndi zowunikira za G-Sync.

Ndipo, kachiwiri, mutha kuyambitsa G-Sync pa FreeSync monitor popanda satifiketi ya Nvidia, koma magwiridwe antchito angalephere.
