If you have a new LG TV, you may have noticed that the picture was strangely smooth. This effect, which LG calls "TruMotion", tries to make the image of your TV smoother, but often ends up looking strange.
What is "TruMotion"?
TruMotion is LG's implementation of motion smoothing. Smoothing movement works by increasing the framerate (the speed at which your TV shows a new image) of the video by inserting "fake" extra images between each real image. Most movies and TV shows are shot at 24 frames per second (FPS) and, by guessing what intermediate images look like, your TV can increase the number of frames per second up to 48 or 60 FPS. This may give a much better appearance to some fast-paced content (such as sports), but ruin the cinematic quality of movies and TV shows for some people.
While the high refresh rate video is quite strange in itself, the other problem with motion smoothing is that it is a false effect and often makes the "fake" images very fuzzy. As we must guess, he ends up losing a little time, which can make everything worse.
How to disable TruMotion
You can disable the TruMotion feature in your TV settings. LG's settings, however, are a little abnormal. Their TruMotion technology also supports synchronized backlight scanning, which synchronizes the refresh rate with the backlight. They say you can not turn off this feature on TVs, but you can adjust the motion tween, which gives TruMotion a weird look.
LG hides the option under Image Menu> Image Mode Settings> Image Options. From there, you can set different levels for TruMotion:
Off: probably what you want
Smooth: uses motion blur
Delete: does not use directional blur
Clear Plus: uses backlight scanning in addition to interpolation
If you have a problem finding the option, it might be in another section. It is therefore best to consult the manual of your TV. you can find online. Simply enter the model number of your TV and, once the page is loaded, use Ctrl + F (or Command + F on Mac) to search for "TruMotion".
It is possible that some older TVs do not even have an option to turn it off. In this case, you will have to buy a new TV if you want to disable it.
