ULMB does not work at 144Hz.

title says it all i saw linus's new video on his benq g-sync review he said that ulmb only works at 120hz and below saying nothing about 144hz so i wonder i have the xl2420z pretty much the same but no gsync does ulmb work at 144hz?

I think he meant that it works at 144hz mode (not 120hz mode) as long as gsync is not being used

Yeah, same thing on my monitor except I have to use the custom lightboost utility to achieve the results.

 

What the blur reduction does is basically use strobing on the display. This is somewhat similar to what CRTs had back in the day and is one of the reasons why people were swearing by LCDs, especially those who played fast-paced shooters. Now, the strobing technique was originally used for 3D Vision 2 to make the monitor brighter in 3D mode. Then someone tried forcing the feature in 2D-mode, and noticed the benefits. The 3D-mode was 120Hz max (60Hz / eye), even on displays that had 144 Hz possiblity.

 

The strobing does not work with G-sync, either. I'm not sure why they haven't moved onto supporting the highest freqeuencies yet, but I'd say that the difference between 144Hz and 120Hz isn't critical.
