If you have a new LG TV, you may have noticed that the image feels fat-free. This effect, which LG calls "TruMotion", tries to make the TV's picture softer but often stops looking strange.
What is TruMotion? Anyway?
TruMotion is LG's motion smoothing implementation. Motion equalization works by increasing framerate (the speed at which your TV displays a new image) of the video by adding extra "false" frames between each real frame. Most movies and TV shows are shot at 24 frames per second (FPS), and by guessing what the intermediate frames would look like, your TV can bump the front row up to 48 or 60 FPS. This can make some fast content (like sports) look much better, but destroy cinematic quality of movies and TV shows for some people.
While video with high refresh rate is weird looks enough on its own, the other problem with motion smoothing is that it is a false effect, and often makes "fake" frames look very blurry. Because it must guess it stops being a bit of the time, which can make it look even worse.

How to turn off TruMotion
You can disable the TruMotion function in the TV settings. However, LG's settings are a bit abnormal. Their TruMotion tech also handles synchronized backlighting, which synchronizes the refresh rate with the backlight. They say you can't turn it off on any TVs, but you can adjust the motion interpolation, which is what makes TruMotion look strange.
LG hides the option under Picture menu> Picture mode settings> Image options. From there you can set different levels for TruMotion:
- Off: Probably what you want
- Smooth: Use motion blur
- Clear: Do not use motion blur
- Clear Plus: Also used backlight scanning for interpolation
If you Having trouble finding the option, it may be under another section, so it is best to read your TV manual, which you can find online. Just enter your TV's model number and, when the page is loaded, use Ctrl + F (or Command + F on Mac) to search for "TruMotion."
It is possible that some older TVs may not even be able to turn it off, in which case you will have to purchase a new TV if you want to disable it.
