What Does LG TrueMotion/Refresh Rate Mean? Is Your TV Really 120Hz?

Sometimes we would find LG TV advertises that it supports TrueMotion 120Hz. What does that mean? Like all 120Hz TVs, the screen itself refreshes at 120Hz but the TV only takes a 60Hz input.

What does refresh rate mean?

As you can understand, the refresh rate is the number of times the screen is refreshed per second. What we see when watching movies is actually a pair of still pictures, like a slide show. Why do we feel the picture is moving, that is because the human eye has a visual stay effect, the impression of the previous picture in the brain has not disappeared, and the next picture has followed up, and the difference between the two pictures is very small, one action requires many pictures to display, so that we feel that the picture is moving. This replacement picture is refreshing. Assuming that an action is completed by 20 pictures, it looks a bit like an animation and when the action increases to 30 pictures, if it does, it looks more natural, this is the refresh rate.

What confuses most people is when TV manufacturers advertise such a feature as ‘Motion Rate 120’ which may trick people into thinking that the TV has a native 120Hz refresh rate. Instead, it’s a 60Hz TV that can simulate 120 FPS content.

what is trumotion 120 refresh rate 60hz How to tell the real refresh rate?

Broadly, most of these features have the word ‘Motion’ in their brand name and in most cases, a number ‘120’ indicates that the TV has a native 60Hz panel whereas everything higher including 240, 960, 1440 usually means that the TV has a 120Hz native panel.

Since some TV manufacturers don’t show the real refresh rate on the specifications sheet, you’ll have to look for a detailed review of the TV if you want to know both its native refresh rate and its effective/simulated refresh rate.

TruMotion, a designation used in LG TVs. At first, the indicator was measured in hertz, but since TruMotion has nothing to do with frequency. After a couple of years, this indicator became simply a number. In short, TruMotion. This is the motion index, which says that the TV shows a quality commensurate with the display of the video with the frequency specified in Trumotion. Samsung has such a technology called Clear Motion Rate.

TruMotion 100, TruMotion 120: Such indices are assigned to entry-level TVs, in such TVs a matrix with a frequency of 60 Hz image support is installed.

The TruMotion 200, TruMotion 240 index is assigned to televisions with improved screens that support 120 frames per second.

The greater the frequency of image display is better.

Increasing the frequency of the output image will slightly smooth moving image by overlapping frames, if the original video has a frequency of 60 frames per second frame is duplicated 2 times more can be achieved in the frequency of 120 frames. Also added televisions able to create intermediate frames of two adjacent but artifacts that occur when creating the intermediate image, and the playback delay time depends on the signal processing (the more dynamic components the longer it is necessary processor for processing), spoil the whole picture.

For normal viewing video is better to switch off TruMotion. You can not really tell the difference between the video at 60 frames per second and video with frequent 120 frames per second.

☺ yes, turn off the trumotion
