If true, this could be a real game changer. 25% BFI at 4K/120Hz. So that means 2ms MPRT motion clarity at 4k 120 Hz smoothness all with OLED HDR picture quality. 13 ms input lag too which is tolerable.

If these sets will truly have 48 GBps HDMI 2.1 chips, wow this is huge news. These TV's will wreck havoc in the high end computer gaming display segment.

EDIT: re-reading it I believe they mean 25% BFI is the black frame is displayed for 25% of the time (~2ms) and the lit frame 75% of the time (~6ms). That would be how they reduce perceived flicker and maintain brightness over 50% BFI. So the motion clarity would "only" be 6ms MPRT, but still better than 8ms!

Confirmed full spec HDMI 2.1! As soon as HDMI 2.1 GPU's hit, a C9 OLED will be mine. Bye bye computer monitors.

Variable rate strobing has been experimented with GSYNC+ULMB simultaneous hack.
So it's possible to do, but require extremely steady frametime changes.

I don't think this TV can combine BFI and VRR, and also the BFI is only in 4.2ms granularities due to its refreshing architecture, so the minimum persistence you can get is 4.2ms on this OLED display. Still a big improvement from 2017 OLEDs!

Ya I think full sample-and-hold VRR smoothness will win out versus needing to lock FPS at 120 at 4K to get smooth 25% BFI. 25% BFI isn't that huge of a deal.

From what I hear
It's 25% BFI at 60Hz
It's 50% BFI at 120Hz

I understand that the BFI is in 1/240sec granularities.
