If you have a new LG TV, you may have noticed that the picture feels incredibly smooth. This effect, which LG calls "TruMotion," tries to soften the image of your TV, but it often looks strange.
What is "TruMotion"
? TruMotion implements LG Smoothing. Motion Smoothing works by increasing the frame rate (the speed at which your TV sets a new picture) of the video by inserting extra "false" frames between each real frame. Most movies and TV shows are shot at 24 frames per second (FPS). By guessing what the intermediate images would look like, your TV can boost the frame rate to 48 or 60 FPS. This may result in faster content (eg in sports) looking much better, but for some people the movie quality of movies and TV is no longer useful.
High frame rate video is strangely enough, the other problem Smoothing motion is a fake effect that makes the "wrong" frames often blurry. Since he has guessed, things have often gone wrong, which can make it look even worse.

You can disable TruMotion in your TV's settings. The settings of LG are somewhat unusual. Its TruMotion technology also manages synchronized backlit scanning, which synchronizes the refresh rate with the backlight. You say you can not turn this off on any TV, but you can set the motion interpolation, which makes TruMotion look funny.
LG hides the option under Picture menu> Picture mode settings> Picture options. From there you can set different levels for TruMotion:
- Off: Probably what you want
- Smoothing: Use motion blur
- Clear: Do not use motion blur
- Clear Plus: In addition, backlit scanning is used for interpolation
If you have trouble finding the option, it may be another section. Therefore, read the instruction manual of your TV that you can find online. Just enter the model number of your TV and look for "TruMotion" after loading the page with Ctrl + F (or Command + F on the Mac).
It is possible that some older TVs may not even have an option to turn off. In this case, you will need to buy a new TV if you want to disable it.
