The LG C9 is able to remove judder from all sources. To do so, simply enable the Real Cinema setting from the 'Picture Mode Settings' menu. Note that with OLED Motion enabled, there will always be 24p judder, even with Real Cinema enabled. GamingLG OLED's are using 120 Hz panels, they will do 5:5 pulldown to the 24p input signals from external sources or internal apps with Real Cinema On; for judder-free native 24p playback. For 24fps content it will display each frame 5 times. 24 * 5 = 120, the exact refresh rate of the panel in Hz. It's the rapid pixel response rate rather than a flaw, it's there on every OLED any any other screen tech with as fast a response but some users are very sensitive to it. It was disguised in other screen tech because of the slower response rate blurring the motion slightly. Cinema projection shows each frame twice to alleviate the judder effect.
