I just purchased a new ASUS RoG 17". I noticed that it says Supported G-Sync however the other G751/G752 at the higher price point say "With G-Sync". Does anyone know what this means? Will this laptop do G-Sync or what are they referring to? It is even listed this way on 3rd party sites for their product description.
