Nvidia after test confirms that G-Sync module requires no hardware for laptops




Nvidia’s G-Sync technology, which prevents tearing and stuttering while gaming, comes to laptops and then requires no additional hardware module. Nvidia confirms that after a test driver G-Sync on a laptop was possible to make.

Using G-Sync run the GPU and display synchronously. If the video chip calculates a frame, a signal to the screen ensures that the refresh of the screen is put equal to this. This should prevent stuttering and tearing and provide smoother playback of images.

Last week was published in a blog Gamenab the claim that Nvidia’s G-Sync was a marketing ploy. The technology also working on a laptop with the GeForce GTX 980M, as shown on the site, and a hardware module was not necessary. Nvidia brings monitor manufacturers money charged for the use of that module and displays with G-Sync support are therefore more expensive than variants without support.

G-Sync Asus ROG laptop

The ability to G-Sync to get a laptop acting came after an alpha driver for the Asus ROG G751 appeared. After installing the laptop showed a pop-up that was found a G-Sync screen and the technology proved to actually work. Gamenab concluded that the module was a disguised DRM component and G-Sync basically did the same as VESA’s Adaptive-Sync variant that is possible on any screen with DisplayPort 1.2 and embedded display port. The Adaptive sync standard comes from AMD’s Free Sync .

PCPer delved deeper into the subject and received G-Sync also working. The site speculated that G-Sync indeed an Adaptive-Sync-like fashion works and that the timing controller of the LG laptop screen was capable of such variable refresh rate to make sure it was good enough for G-Sync. It also was a panel with a maximum refresh rate of 100Hz. The operation would have some drawbacks. As the screen showed dropouts with low fps and unexpected transitions to 0fps. A display with a G-Sync module here would have less problems.

Inquiry at Nvidia learned that laptops actually get support for G-Sync without a module is required. The driver in question was intended for manufacturers to be able to advance to troubleshooting. The manufacturer could optimize the technology by allowing Nvidia knows the specific implementation of the panels and timing controllers. The big question now is whether Nvidia still find it necessary to require to support G-Sync hardware module with displays. That question is still not answered by the company.
