So, we all know that the LG C9, like EVERY other OLED and QLED can only deliver 300 lines of motion resolution, but how many lines of motion res do you get when using it's BFI? I've heard it doubles, or gets up to 700, which is it?
As is, the C9's BFI for streaming is useless to me solely because it can only achieve just under 140 nits of brightness. i need at least 200 nits in a dark room based on what i like. There does seem to be a big reduction in motion blur using BFI, which is especially noticeable when gaming. The best test for this would be putting on a game that runs in 60fps, and turning the screen in circles. without BFI, the C9 has only 300 lines slathered in a big haze of BLUR. it's terrible, not as bad as most smeary QLEDs, but it's NO plasma(at it's best) and definitely no CRT(Zero blur). But with the C9's BFI the playing field becomes more even compared to plasma's such as the Panasonic S60 from 2013. That plasma has 700 lines of motion res but it still suffers from blur. I've done comparisons between the the C9 and S60 using a 4K HDMI splitter side by side again with 60fps first person shooters by rotating the screen in cricles...And the results?
When BFI is enabled on the C9, there is actually a 'little' less blur compared to the S60. but the S60 is the clear winner when the C9 isn't using BFI. That aside, BFI increases input lag from about 14ms to 27ms on the C9 & CX, deal breaker right there. I'm looking for under 16ms(120fps gaming content can give you about 7ms) BUT for streaming movies & TV that doesn't matter.
I hope there's a gamer friendly 2021 OLED that has advanced BFI that allows for 200+ nits brightness, 1080lines of motion res and minimal, and i mean MINIMAL blur and hopefully only a couple or few ms of extra latency. fingers crossed. because as is, the C9 is NOT worth the asking price. it's plagued with black crush, too much motion blur for me, 300 lines of motion clarity, WRGB color, color volume is kind of weak and that annoying ABL which drops brightness to 140 nits. I'm dying for a 65", but i'm gonna hold out and wait for reviews this spring for the 2021 models
