What type of bfi,buffer and scan out of lg c1 c2

30 fps at 60 Hz with Motion Pro High will not have the same motion clarity as 60 fps at 60 Hz because you'll get double images when BFI flickers twice as often as the input content.

In HDTVTest's review of the LG C1 Vincent measured:

120 Hz: 5 ms
120 Hz (Motion Pro enabled): 13 ms
60 Hz (Boost Mode enabled): 10 ms
60 Hz (Motion Pro enabled): 21 ms

Note that Vincent measures the time an input signal needs to become visible in the middle of the display. Other people measure top or bottom which gives different results.

So in the end you get between 8 and 11 ms extra input latency when engaging Motion Pro. You are the only person who can judge if that's too much for you. For me personally I always played with Motion Pro (Rocket League for example) and never had issues.

How to use hdmi2.1 qft on aw3423dw 175hz oled
With 3060ti,1060,steam deck

Does qft works with 175fps>175hz to reduce high refresh rate input lag?
Thank

That depends on your display and your source device.

I think the Xbox Series X has a setting that enables permanent 120 Hz output even if the game runs at 60 fps. In this case QFT is solved by the source device.
The other way would be if your display supports QFT. I am not sure if that works with every 60 Hz output source device but I guess so.

Did you say sub refresh on c1 that means if input 4k 60hz to it,then c1 refresh 60 per frame a second

I watched a YouTube video about c1 high shutter that you posted,why is there a scanning line across the screen from top to bottom when bfi
Off

It looks a scanning line of crt recorded on a regular shutter speed camera recorder

Does c1 refresh 60 frame per second when input 60fps with 120hz input

2.i have a lcd x900e which support 120fps with 120hz bfi only but no 60fps with 60hz
That’s not like c5 with only 60fps to 60hz bfi
LCD may use global insert a full black frame unlike sub refresh rolling scan of c1
Where does a 120hz lcd insert a black frame to..because it is only 120hz but not 240hz,there is no headroom to bfi


3.this lcd is a 4k resolution 120hz refresh rate but a hdmi2.0 port with 1080p 120hz,not possible to 4k 120hz
Is there any trick to run game in 4k 120hz in this tv

Motion pro medium is probably full screen BFI.
Motion pro High is probably rolling scan bfi.
I have lg c1 . i will make slow motion video, but i can only make 240fps slow motion.

That's not how OLED Motion Pro works. Low, Medium and High just change the ratio of image to black on the rolling scan. So High is the best motion clarity (~310Hz) but is the dimmest. There is a YouTube video that explains it perfectly but BB Forum wont let me post a link to it.

Paste this video code into YouTube search to find it [ yDGXbML3gUY ]

Its such a shame Blur Busters never did a deep dive on these LG OLED TVs (CX and C1) with 120Hz rolling scan BFI before LG removed it. It was pretty unique among OLEDs.
