NVIDIA’s ULMB 2 Reduces Motion Blur in Competitive Gaming

NVIDIA has unveiled the second generation of its Ultra Low Motion Blur (ULMB) technology. Designed to reduce motion blur in competitive games, ULMB 2 offers more brightness and almost no strobing or double-image effect that sometimes appears when blur reduction features are enabled. The company claims that the new technology has been able to match the display’s refresh rate when it turns the backlight on and off, which results in an effective motion clarity of over 1000Hz.

Improving Motion Clarity

Motion clarity is largely determined by the monitor’s pixel response time. NVIDIA is using full refresh rate backlight strobing, which builds on the backlight strobing technique from the original ULMB. The previous version of the tech improved motion clarity, but it needed to switch off the monitor’s backlight 75% of the time, which reduced the screen’s brightness. With ULMB 2, NVIDIA is able to run at the full refresh rate of current displays, allowing each backlight strobe to happen every 2.7 milliseconds, a rate that’s imperceptible to the human eye.

The Benefits of ULMB 2

NVIDIA has been able to offer more brightness with ULMB 2. Using ULMB 2 with a 360Hz monitor, the company claims that users will get an effective motion clarity of 1440Hz, something that would require a monitor capable of 1440Hz without ULMB 2. The technology is available now as a free update for compatible 1440p, 360Hz G-Sync monitors.

Compatible Monitors

Only two displays are currently on the market that are compatible with ULMB 2. These include the Acer Predator XB273U and the ASUS ROG Swift PG27AQN, both of which are 27-inch monitors. The ASUS ROG Swift Pro PG248QP (a 25-inch 1080p, 540Hz display) and the 27-inch AOC AGON AG276QSG G-Sync Monitor are also compatible soon, according to NVIDIA.

Conclusion

NVIDIA ULMB 2 is a breakthrough technology that offers almost no motion blur in competitive games. The technology builds on the original backlight strobing technique, allowing each backlight strobe to happen every 2.7 milliseconds. The company has been able to offer an effective motion clarity of over 1000Hz, and it is available now as a free update for certain compatible monitors.

FAQs

What is ULMB 2?

ULMB 2 is the second generation of NVIDIA’s Ultra Low Motion Blur technology. It is designed to minimize motion blur in competitive games.

What is motion clarity?

Motion clarity refers to how well a monitor can display moving images without blurring or ghosting. It is largely determined by a monitor’s pixel response time.

How does ULMB 2 improve motion clarity?

NVIDIA is using full refresh rate backlight strobing, which builds on the backlight strobing technique from the original ULMB. Unlike the previous version, ULMB 2 can run at the full refresh rate of current displays, allowing each backlight strobe to happen every 2.7 milliseconds, which results in an effective motion clarity of over 1000Hz.

What monitors are compatible with ULMB 2?

ULMB 2 is currently available as a free update for compatible 1440p, 360Hz G-Sync monitors. These include the Acer Predator XB273U and the ASUS ROG Swift PG27AQN. The ASUS ROG Swift Pro PG248QP and the AOC AGON AG276QSG G-Sync Monitor will also be compatible soon.
