This is why G-Sync and G-Sync Ultimate monitors are becoming less common. Nvidia’s G-Sync and G-Sync Ultimate are technically superior, but require proprietary Nvidia hardware that adds to a display’s price. AMD FreeSync and Nvidia G-Sync Compatible are essentially certification programs that monitor companies can use to slap another badge on a product, though they also ensure out-of-the-box compatibility with supported graphics card. That leaves AMD FreeSync and Nvidia G-Sync searching for a purpose. AMD FreeSync and Nvidia G-Sync Compatible may struggle with that, but Nvidia G-Sync and G-Sync Ultimate won’t have a problem. This is important if you play games that may hit lower frame rates, since Adaptive Sync matches the display refresh rate with the output frame rate.įor example, if you’re playing Cyberpunk 2077 at an average of 30 FPS on a 4K display, that implies a refresh rate of 30Hz – which falls outside the range VESA Adaptive Sync supports. G-Sync and G-Sync Ultimate support the entire refresh range of a panel – even as low as 1Hz.
A refresh rate below that can cause dropouts in Adaptive Sync, which may let screen tearing to sneak back in or, in a worst-case scenario, cause the display to flicker. The VESA Adaptive Sync specification has a minimum required refresh rate (usually 48Hz, but sometimes 40Hz). The most important is G-Sync’s support for a wider range of refresh rates.
