MojoKid writes "Back in September at a press event in Montreal, NVIDIA CEO Jen-Hsun Huang announced what he called “one of the most important works NVIDIA has done for computer graphics.” The technology was called G-SYNC. G-SYNC is an end-to-end graphics and display architecture that starts with a Kepler-based GPU and ends with a G-SYNC module within a monitor. The G-SYNC module is piece of hardware that replaces the scaler inside a monitor that essentially does away with the fixed vertical refresh rates of current displays. To put it simply, what G-SYNC does is keep a display and the output from a Kepler-based GPU in sync, regardless of frame rates or whether or not V-Sync is enabled. Instead of the monitor controlling the timing, and refreshing at say every 60Hz, with G-SYNC the timing control is transferred to the GPU. NVIDIA achieved this by developing the G-SYNC module, which will be featured in a number of new monitors starting next year. The G-SYNC module replaces the scaler and controller boards in current displays and allows for the dynamic refresh rates mentioned earlier. The module is comprised of an FPGA—programmed by NVIDIA—a bit of DRAM, and a DisplayPort input. At this time, G-SYNC requires a Kepler-based GPU, with a DP output, and obviously a G-SYNC enabled display. To fully appreciate the technology, a high-DPI gaming mouse is also recommended."
