"
The absence of a Native G-sync module might cause some complications here with usage of the Mini LED backlight at the same time as VRR. That is incredibly complex to develop and one of the reasons why current FALD and Mini LED gaming monitors use the G-sync module. We will wait to see how this performs on the Samsung Odyssey G9v2 and whether the Mini LED backlight can keep up with VRR and gaming properly and effectively."
