Nvidia launches G-SYNC ULMB 2 technology: Provides effective motion clarity over 1000Hz

In 2015, NVIDIA introduced G-SYNC ULMB (Ultra Low Motion Blur) technology, a strategy to control monitor backlight flickering, mitigating motion blur, and thereby granting e-sport games an additional layer of motion clarity. Today, NVIDIA unveils the next generation G-SYNC ULMB 2 technology, capable of offering over 1000Hz effective motion clarity, rendering an even smoother and crisper gaming experience for e-sport enthusiasts.


During rapid movements in game visuals, the edges and details of objects tend to blur. However, with G-SYNC ULMB technology, the quality of dynamic visuals can be enhanced. Despite its advantages, this technology harbors certain drawbacks such as the necessity to lower refresh rates and compromise on brightness. This is partially due to the constraints of panel technology at the time, which required an elongated transition time for pixels to reach the correct position. For players necessitating ultra-high refresh rates and brightness, the potential downsides may outweigh the benefits, leading to many players choosing not to use G-SYNC ULMB technology.

The novel G-SYNC ULMB 2 technology proffers full refresh rate backlight flickering, with the brightness nearly doubling. The backlight is activated only when each pixel reaches the correct color value, void of any double imaging or crosstalk issues. With the advancements in G-SYNC ULMB 2 technology, it is capable of achieving over 1000Hz effective motion clarity, satisfying e-sport players’ pursuit of high refresh rates.

Within the market, two available monitors support the G-SYNC ULMB 2 technology: Acer Predator XB273U F and ASUS ROG Swift 360Hz PG27AQN, both being 27-inch 2K @360Hz monitors. Additionally, two imminent models, ASUS ROG Swift Pro PG248QP and AOC AGON AG276QSG, will also be made available.

The G-SYNC ULMB 2 technology is currently available for free trials. Gamers using the aforementioned monitors can support new features with a one-click firmware update. Players merely need to disable the G-SYNC variable frequency function in the NVIDIA control panel and activate the G-SYNC ULMB function within the monitor’s menu.
