We were first given a taste of NVIDIA G-SYNC technology over a year and a half ago and it was definitely quite a sweet dish. Like competing solutions from AMD (FreeSync), G-SYNC aims to rid gamers of synchronization-related maladies like VSync input lag, stuttering and screen tearing, providing instead a buttery smooth gaming experience. For an in-depth look at G-SYNC, you can take a look at Marco’s excellent article about the technology right here.
Up until this point, G-SYNC has been solely aimed at desktop gamers, but NVIDIA today is extending its reach by bringing a new implementation of G-SYNC to notebook computers. On the desktop side things, gamers are required to have both a Kepler-based GPU and a G-SYNC-enabled monitor from the likes of ASUS, Philips, or Viewsonic (among others) in order to reap the benefits of G-SYNC gaming. In order to claim G-SYNC compliance, these display manufacturers have to incorporate a special G-SYNC module built by NVIDIA (the module incorporates both the scaler and necessary circuitry required to support dynamic refresh rates).
However, with notebook gaming, there is no need for a separate G-SYNC module, as the GPU connects directly with display panel. Now these aren’t just garden variety panels that you would find in typical gaming notebooks; these panels have not only been approved by NVIDIA, but also have been tested to ensure that they minimize ghosting while gaming and to ensure that the panels are capable of handling the rigors of pixel overdrive (which basically amounts to zapping pixels with extra voltage to improve response rates).
These high-end panels are also the first to support 75Hz refresh rates, which is an equally noteworthy advancement in notebook gaming.
NVIDIA has signed up a number of heavy-hitters in the gaming notebook field including Gigabyte (which will have two G-SYNC entries including the 15.6-inch Aorus X5 with a GeForce GTX 965M SLI configuration and a 3K display), the 17.3-inch ASUS G751, the 17.3-inch MSI GT72 G, and both a 17.3-inch and 15.6-inch (4K) offerings from Clevo.
