So this new rolling bar motion solution of LG's...is it independent of input source and input frequency? Sounds like it might be a real game changer on that front.Some new information regarding BFI, which it seems will be present in LG's 2020 OLEDs.

"With its 2020 OLED TVs, Sony will introduce X-Motion Clarity, which is made possible by LG Display's upgrade to a functional BFI system (Black Frame Insertion). The system will continuously "scan" the OLED display, meaning that a dark bar will roll (at 120Hz) from the top to the bottom - rather than using fullscreen black frames. The intended purpose here is to cancel the human eye's inherent memory effect that is a primary source for the perception of motion blur on LCD and OLED TVs (with sample-and-hold driving). By using these scanning effects to constantly "reset the eye", moving images will appear sharper. The scanning effect of the new BFI implementation is also faster than most eyes can perceive so we avoid negative effects such as flickering or reduction in brightness.
...the 120Hz BFI system... was intended to be included in the 2019 models but was pulled in the eleventh hour. It will now make its debut in 2020 OLED TVs and we look forward to testing it as soon as we get our hands on review samples."
