NVIDIA's G-SYNC revolution requires monitor manufacturers to replace their scalar with a G-SYNC, trading in the freedom to scale settings like input frame, color hue, intensity and contrast for pure speed and smoothness of the game. With the best efforts of R&D champions, you can keep your options open with the world's first hybrid engine design. So you are in control of matching your choice of gameplay. For those in favor of perfect motion gaming that can be tailored to match their gameplay preferences, the classic mode offers a wide array of customizable settings, from motion blur reduction to gaming refresh rate optimization management (GROM), Black eQualizer, display pilot, smart scaling, S switch, and game mode loader. The mode also features BenQ's exclusive Gaming-comfort flicker-free technology and low blue light modes to help protect your eyes from computer-related discomfort. In essence, it's a total package solution for agile performance, precise control, intuitive user experience and eye comfort. What's more, with this mode, you can be sure to get the best gaming experience for games unsupported by the G-SYNC mode. By synchronizing the XL2420G's display refresh rates to the GPU in a GeForce GTX-powered PC, the G-SYNC mode enables images to appear instantly the moment they are rendered. The low latency effectively eliminates screen tearing, and minimizes display stutter and input lag - frame rate artifacts commonly seen in high-motion gaming. Ultra low motion blur (ULMB) is also at your disposal to smooth the way for a near-zero motion blur performance. Ultimately, with NVIDIA's G-SYNC technology, an unprecedented buttery smooth, ultra-responsive gameplay to victory is all you'll get.
