Lowering movement blur is a kind of issues that improves gaming in an actual however refined means — you usually want a stay demonstration to see simply how a lot better it makes issues. Take Nvidia’s ULMB (extremely low movement blur) system, which has been obtainable for G-Sync shows since 2015. The corporate simply took the wraps off of a sophisticated ULMB 2 implementation, and it’s spectacular…should you’ve received a quick sufficient monitor to utilize it.
ULMB 2 works on G-Sync shows of 360Hz or increased, basically limiting its implementation to high-end esports setups (at the very least for the second). The improved system provides full refresh charge backlight strobing and has double the efficient brightness, one of many weaknesses of high-refresh shows throughout the board. To show the development in a means that’s seen on any show, Nvidia used super-slow movement to match the motion of a Fortnite motorbike with ULMB 2 on and off:
It’s an enchancment over present high-refresh shows, too. Right here’s a 120Hz panel with out the backlight strobing characteristic in comparison with a 480Hz panel with the characteristic enabled:
The brand new ULMB 2 system depends on a way Nvidia calls “Vertical Dependent Overdrive,” which syncs the LCD panel’s backlight strobing with the portion of the picture the place pixels are actively in movement. This makes the vertical scan (the a part of G-Sync that ensures the entire display screen refreshes without delay) timed completely to offer the smoothest movement. It’s sufficient to make the efficient movement readability “over 1000Hz” whereas sustaining extra brightness.
To date there are solely two screens in the marketplace which might be suitable with ULMB2, the Predator XB273U F from Acer (which PCWorld reviewed earlier this yr!) and the ROG Swift PG27AQN from Asus. (Two extra are coming quickly, from Asus and AOC, and extra must be hitting the market within the latter a part of the yr.) When you occur to have one in every of these shows, you’ll be able to allow ULMB 2 with a brand new firmware replace obtainable as we speak.
