Nvidia is updating its Extremely Low Movement Blur (ULMB) know-how, which might make gaming even smoother on high-end displays. In an announcement on Sunday, Nvidia says its upgraded ULMB 2 characteristic is able to offering over 1,000Hz of efficient movement readability with “virtually zero” crosstalk — however solely on 1440p 360Hz G-Sync displays for now.

This implies you now not have to decide on between having a extra responsive refresh price or lowering movement blur, each of which have an effect on gameplay. Now Nvidia says the efficient movement price for a 360Hz monitor with ULMB 2 enabled is 1440Hz. “Which means in an effort to acquire the identical stage of movement readability with out ULMB 2, avid gamers would want a basic panel able to 1440 Hz,” Nvidia notes. You continue to can’t use it with variable refresh price, although.

In the event you’re inquisitive about how this all works, HotHardware has a great write-up detailing a few of the technical features behind movement blurring and ULMB 2. Mainly, since LCD and OLED displays are “sample and hold” displays that solely present static pictures till it refreshes, this leads your mind to see a blur connected to no matter your eyes are monitoring throughout your display screen, just like the best way that fast-moving objects seem blurry in actual life.

There are already a few strategies LCD and OLED displays use to scale back movement blur, however neither does an ideal job. Some displays rapidly flash a backlight on the similar time it refreshes a picture, mimicking good ol’ CRT displays, whereas different shows construct upon this by including a very black picture between every body to assist cut back blur. Each of those strategies may cause disagreeable unwanted effects, nevertheless, as they will make pictures seem dimmer and might trigger a flickering impact.

However with ULMB 2, Nvidia is hoping to enhance on these points with full refresh price backlight strobing and improved brightness. As a substitute of utilizing the backlight to indicate how every pixel transitions from one coloration to the following, Nvidia says displays with ULMB 2 will solely shine the backlight on a pixel when it has absolutely accomplished the transition to its new coloration.

The corporate provides that the upgraded ULMB 2 ensures that the “pixels all through the panel are on the proper stage at exactly the best time for the backlight to be flashed,” mitigating one thing known as crosstalk, a problem that creates double pictures on a show when an object is in movement. It will possibly additionally ship 250 nits of brightness, which Nvidia says nearly doubles the quantity of brightness provided by the unique ULMB.

You may see ULMB 2 in motion within the video embedded above, and it’s fairly spectacular. Sadly, the characteristic isn’t out there for a variety of G-Sync displays simply but, as you may solely use the characteristic after making use of a firmware replace to the Acer Predator XB273U F or ASUS ROG Swift PG27AQN, each of that are 1440p shows that run at 360Hz.
