NVIDIA's G-Sync technology might soon work without the G-Sync module

NVIDIA's G-Sync technology confirmed, and tested as working in a new driver without the G-Sync module

NVIDIA has been in the headlines for all the wrong reasons this week with the GeForce GTX 970 VRAM issues, and now someone has played around with NVIDIA's G-Sync technology and got it working on every eDP display thanks to the use of a very special driver.


The driver has come from an ASUS Nordic Support representative, who leaked the internal driver (346.87) that included hidden G-Sync support. The driver itself was issued to fix a totallyt different issue, with the rep not aware that G-Sync support was added. Well, when the person received the driver and installed it, they were met with a popup saying that a G-Sync display had been connected. The leaked driver has been adding support for G-Sync to some notebooks, with the ASUS G751 being one of those.

NVIDIA confirmed with PC Perspective that this technology is still in a very early stage, with the G-Sync support not meant to be added anytime soon. NVIDIA had inadvertently confirmed that a G-Sync module is not required to enable G-Sync, which is where the excitement should begin for most.

PC Perspective has done a deep dive into this, where they've said: "This obviously leads us to the discussion of the need for a dedicated G-Sync module on current monitors. In order to get shipping variable refresh monitors in the market last year, NVIDIA had no choice but to create a module to replace the scalar in modern displays. No monitors existed then with embedded DisplayPort interfaces and the standard had not been created for Adaptive Sync". The site continues: "But as the release of AMD FreeSync displays nears, we have to ask: will a dedicated module be required for G-Sync on future products? Interestingly, NVIDIA says that the answer hasn't been 100% decided yet - the future could include this same module, a new module or perhaps even no module at all. There are features and technologies in the G-Sync module that haven't been revealed, at least according to NVIDIA, and with that line of thinking I don't see a time when NVIDIA relieves the desktop market of that requirement in the near term".
