If you have recently spent time exploring your options in terms of computer monitors, it is quite possible you will have encountered references to a technology from Nvidia called ultra low motion blur, or ULMB for short – but what is ULMB and how important is it?

Keep reading for more information on the technology itself, how it works, and when it may be beneficial.

Answering the question of ‘what is ULMB?’ is important, because it is a relatively new technology, offered by Nvidia, which is associated with a growing number of computer monitors and which is showing up in more and more control panels. While many are aware that the initials stand for ultra low motion blur, some are less clear on what this actually means, how the technology works, when it should be used, and what the main benefits are.

This article aims to provide the answers you are looking for.

ULMB Explained: What is ULMB?

As stated, ULMB stands for ultra low motion blur and is a technology that was developed by Nvidia, primarily to reduce motion blurring on the screen. The technology is found on some G-Sync computer monitors and works by strobing the backlight at the same rate as the refresh rate of the screen.

ULMB can currently be used with monitors with a refresh rate of 85, 100, 120 or 144 Hz. Additionally, you will want a frame rate of more than 120 fps and your minimum frame rate should ideally be the same as the refresh rate. So if your refresh rate is 120 Hz, your minimum frame rate should be 120 fps, and so on.

Although Nvidia is responsible for both ULMB and G-Sync technology, the two cannot be used at the same time. With this in mind, it is important to cover the precise situations where you should consider using ULMB.

What is ULMB - What to use

When to Use Ultra Low Motion Blur

First, it is worth highlighting the fact that ultra low motion blur can have a slight impact on overall picture quality. Although this is minimal, it means it is not the ideal solution for any use where pure picture quality is the number one concern. Instead, ULMB is best utilized when you need to reduce motion blur as a top priority.

A good example of this would be a first-person shooter video game. Precise movement is absolutely critical in such a game, as is precise aiming, which means reducing motion blur could improve your performance. This makes it a useful setting on a high-quality gaming monitor. However, even then, it is not always applicable.

Perhaps the most crucial requirement is a high and stable frame rate. If you are playing a game and you are experiencing an unstable frame rate, ULMB is unlikely to be a useful solution to your problems, unless you are willing to upgrade your graphics card and/or CPU to produce a higher and more stable frame rate first.

Final Thoughts

Ultimately, the main purpose of ULMB technology is to keep motion blur to a minimum, so it is a useful technology for situations where that is a top priority, such as competitive gaming. However, it is important to note that it cannot be used in conjunction with G-Sync, and that technology is preferable if you do not have a high, stable frame rate.
