LG OLED CX 120Hz BFI

[Chief Blur Buster]

Why can we not get better than 8ms MPRT with something like an LG C1 OLED at 60fps with BFI? I just got a C1 and I am disappointed with my 60hz MPRT on the C1 vs my old BenQ XL2720Z

That's because newer TV OLEDs and monitor OLEDs can only update a pixel once per Hz. It can't do subframe blackness like CX or like an LCD strobe backlight.

How was it that the CX OLED BFI 60hz is less motion blur? Is there a REASON why this is, or is there a comparison of this somewhere to see it, please?

Certain models like C9/CX could do two pixel updates per refresh cycle, one to turn on pixel and one to turn off pixel. For displays that can do only one pixel update per refresh cycle, your motion blur reduction is throttled to no less than (1/Hz) MPRT.

If you want better 60fps MPRT with a 480Hz OLED, you can run certain software such as RetroArch that has added my brand new implementation of my CRT simulator algorithm, and see up to 87.5% motion blur reduction for 60fps content. It's not as good as 1ms MPRT strobe backlight, but can exceed old strobe backlights like LightBoost.

How does the CX vs C1 stack up with regards to 120hz BFI MPRT? Is there a comparison of this?

Try RTINGs, they have the deets and photographs and numbers.
