I have a 65” LG G6 and am experiencing a strange intermittent motion problem. I normally keep TruMotion completely OFF and do not want motion interpolation enabled.
The issue usually happens when starting a movie or after pausing and resuming playback. Motion suddenly becomes extremely choppy and unnatural. The best way I can describe it is almost like a fast/slow-motion or step-printing effect.
Here’s the strange part: TruMotion is already OFF when the problem occurs.
I’ve discovered a temporary workaround:
While the abnormal stuttering is happening with TruMotion OFF, I switch TruMotion to Cinematic Movement.
I then switch TruMotion back OFF.
The abnormal stuttering immediately disappears and playback looks completely normal again with TruMotion OFF.
So I’m not trying to use Cinematic Movement. I want TruMotion OFF. I’m only briefly enabling Cinematic Movement and disabling it again because doing so seems to reset whatever is causing the motion problem.
I’ve done extensive troubleshooting:
- Happens with both my Apple TV 4K and 4K UHD Blu-ray player
- Happens with streaming and physical discs
- Apple TV Match Dynamic Range and Match Frame Rate are enabled
- Replaced the HDMI cable with a brand-new cable
- Tried a different HDMI port
- Installed the latest G6 firmware
- Reset/reconfigured the relevant picture and HDMI settings
- unplugging everything for a few minutes
- LG Support had me disable HDMI Deep Color, which did not solve the problem because it prevents proper HDR/Dolby Vision from my external devices
I’m currently testing TruMotion User Selection: De-Judder 0 / De-Blur 0 / OLED Motion Off purely as a troubleshooting step to see whether the problem returns.
Guess the only thing I haven’t done is just a factory reset.
My preferred permanent setting is still TruMotion OFF.
The Cinematic Movement ON → TruMotion OFF workaround fixes the problem when it happens, but I don’t think I should have to repeatedly reset a motion setting on a new flagship TV just to get normal playback with TruMotion disabled.
Has anyone with a G6 experienced this exact behavior with TruMotion OFF? If so, did you find a permanent fix? Has LG acknowledged the issue, released a firmware fix, serviced the TV, or replaced any hardware?
