Nowadays, the technology is far more beyond the simple transmitting and displaying the image. Companies are now trying to offer customers unique features that can help make the image better. Sometimes such technologies may help, but sometimes customers don’t like such features. LG TruMotion is one of that kind. While some people are enjoying this feature, the other part doesn’t like this feature and wants it to be turned off. However, there are a lot of people that simply don’t understand what is TruMotion and how is it working.
In this article, we’re trying to explain LG TruMotion and what it can contribute to your TV picture quality.
LG TruMotion what is it?
According to LG, TruMotion is an original technology used in LG TVs to improve the picture quality on your screen. The main feature of this technology is the artificial increase in the smoothness of the image. LG TruMotion boosts your TV screen refresh rate to 100, 200, or even 400 Hz. At the same time, it makes the LG TVs matrix respond faster to color changes. As a result, the picture becomes clearer and more realistic, and the movement is smooth without flickering.
Of course, that’s also the theory, but in practice, a lot of customers are unsatisfied with this feature, claiming it makes the picture quality even worse. The problem is, when TruMotion is turned on, it destroys any film grain and increases the frame rate. On the one hand, the picture becomes better in terms of quality, but on the other hand, you just get something like the Soap Opera effect. The problem is that software image enhancement (especially moving images) creates smoothing, which makes the picture unrealistic, and therefore many people think that TruMotion is a bad feature at all.
How LG TruMotion works?
If the refresh rate of the TV far exceeds the FPS of the source video, the picture you see on the screen may “wobble” and “shake”. This effect is called judder, and technologies like TruMotion (or any other motion smoothing technology) are here to fix this. LG TruMotion analyzes the motion of objects on the screen, and based on that data, it creates new frames and inserts them between existing frames to reduce the judder effect.
To generate new frames, motion smoothing highlights moving objects and sharpens them. To remove blur plumes, the technology analyzes two adjacent frames where these plumes are absent or less pronounced. Accordingly, the image becomes better, as there are no ‘blur’ and ‘judder’ effects anymore.
When LG TruMotion should be used?
LG TruMotion is good for watching sports channels such as football – the ball doesn’t leave traces and it becomes easier to follow fast-moving objects on the screen.
However, this technology has the opposite effect when watching films, as it creates a soap opera effect and ruins the director’s intent. This is especially noticeable in action scenes, where artifacts and lags sometimes occur.
Do all LG TVs have TruMotion?
Yes, all new LG TVs have TruMotion, as the company includes this feature in all new TV models. Of course, if you’re watching your granny TV, it may be too old to have TruMotion, but all new TVs have it. If you aren’t sure this technology is used in your TV, then most likely it’s simply disabled. If you like the Soap Opera effect – you can turn it on at any time.
How the TruMotion index is assigned to LG TVs?
The higher number, the better. TruMotion 100 and 120 are assigned to entry-level TVs, as in such TVs is used matrix with a 60 Hz refresh rate. So TruMotion boosts screen refresh rate x2, up to 100/120 Hz.
TruMotion 200 and 240 are assigned to TVs with improved screens that support 120 frames per second. In general, the higher frequency – the better. But to be honest, you would still get 60 MHz picture quality, just because 90% of all videos are still made with 60 images per second. No matter the frame rate of your screen – if the video was made with 60 images a second, you would get them and nothing more.
Should TruMotion be on or off?
That depends on what you like. My colleague, when I was consulting him about this article said:
– If you want to enjoy the maximum clearness and vividness of the picture, then you should turn it on. The difference is visible while watching sports, movies, and TV shows which contain a lot of dynamic scenes.
Actually, I can’t agree with him. If you like Soap Opera-looking image – you need to keep TruMotion on, if no – then turn it off. Just test different ways and find your best.
Can LG TruMotion be turned off?
How to disable this option? Simple! You can find this option under Picture Menu > Picture Mode Settings > Picture Options. If you didn’t find TruMotion, then it’s best to ask your TV’s manual, which you can also find online. By the way, some older TVs might not even have an option to turn it off. In this case, the only way to disable it is to replace your TV with a newer one.
