NVIDIA G-Sync Pulsar monitor - Acer Predator XB273U F5

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, ToastyX, black frame insertion (BFI), and now framerate-based motion blur reduction (framegen / LSS / etc).

Use whatever you want. If you dont see any improvement in clearness then chose the higher brightness.

Is the 321 Hz issue still there with the new FW udpate?

Sadly yes, it is still there.

The good news is that Nvidia has already acknowledge the bug and they have repro, it seems to be driver related.

So it's just a matter of time until they find a solution to the problem. Let us hope sooner rather than later.
