Difference between BFI and Strobing

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).

Difference between BFI and Strobing

So get this, running an oled panel at 120 hz doubles the motion resolution to 240, given that its the panels default max refresh rate. Yet xg2431 also being a native 240 hz panel when strobed, achieves a much higher motion resolution. Apparently beating crts. BFI seems handicapped to me.

It is handicapped. Especially when it's poorly implemented, adding a ton of input lag. The equivalent of 240Hz clarity is "good enough" for most people, but the input lag thing is just dumb and is the result of lazy manufacturers not caring.

There is another BFI implementation ( i think sub-refresh called) where the frame time can be reduced further like on the LG C1 down to 3.2ms frame visibility time. This equals the ULMB strobe time of 2 to 3ms nearly. Strobing and BFI both reduce the average intensity, however the problem is much worse for the OLED. So yes, one can call that a disadvantage how BFI is implemented for OLED entered the market recently.

Thanks for ur input guys. What further compounds the problem is if u go for a strobed monitor. Ur compromising contrast ratios.
