TruMotion

TRUMOTION

DID YOU KNOW? 

Most video signals are transmitted to a television at a rate of 60 images per second. This means every single image lingers on screen 16 millisecond or 16 thousandth of a second.

Since 1927 the standard in the movie industry has been and still is currently 24 frames per second. With TruMotion 120Hz and Real Cinema feature enabled, every movie frames are being processed 5 times each equally whereas on a normal 60Hz TV, video process needs to resort to 3:2 Pull-Down.

LCD panels regardless of backlighting have this inherent flaw of lagging in between picture succession, panel response time being measured in millisecond. Still images will never be impacted by shortcoming.

However, the moment motion is introduced to the screen and the greater the acceleration the more obvious blurriness or trailing effect on character or object edges becomes.

     
TruMotion technology was introduced to LCD panels to alleviate somewhat flawed processing. By retaining image on screen half the time (120Hz) or a quarter of the time (240Hz) either through black screen insertion, in-between image extrapolation or backlight scanning, blurriness in rapid motion image succession was suppressed for a crisper, cleaner and clearer viewing experience.

ADJUSTING TRUMOTION 

Following instructions apply to webOS6.0 TV models (2021 product line-up and greater). For any Vintage LG Smart TV, please consult very bottom of this article.

Adjusting Picture Clarity

 Picture → Advanced Settings → Clarity

You can adjust Picture clarity options to show it more clearly. Adjustments can be made to the following picture options: Adjust Sharpness,   Super Resolution,   Noise Reduction, MPEG Noise Reduction, Smooth Gradation, Cinema Screen and TruMotion.

TruMotion

Suitable for fast-moving pictures’ image quality transition. This feature is designed to enhance the image transition on screen from content material captured in high speed video format (60 fps). Cinema purists preferring the dreamier escapism of the silver screen texture presentation of 24 fps will enjoy viewing movies while having TruMotion turned “off”.

● Off : Turns off TruMotion .

● Cinematic Movement : Adjusts the shaking of the motion on the screen to make it feel like you are in a movie theater.

● Natural : Sets images with a lot of motions to look natural and clear.

● Smooth Movement : Softens fast-moving pictures.

● User Selection : Sets TruMotion manually.

● De-Judder : Adjusts juddering on the screen.

● De-Blur : Reduces the blurring effects of motion.

● OLED Motion / OLED Motion Pro / Motion Pro / NanoCell Motion Pro : You can make your video clearer by eliminating afterimages.

The advanced settings can be changed only in User Selection   mode.

Depending upon the input signal or the selected picture mode, available options may differ.

The configurable items differ depending upon model.

Applying the Current Picture Settings to All Inputs

 Picture → Advanced Settings → Apply to All Inputs

The settings you specify only applies to the currently selected input mode.

To apply your current picture settings to all input modes, select Apply to All Inputs.

Deciphering Technological Jargon

Motion Blurriness Corrective Measure

Image Judder Corrective Measure

Definition of:  judder

A shaking or wobbling effect in a video image. Judder is often caused by the conversion of 24 frames-per-second ( fps ) movie content to 30 or 60 fps video format, or whenever viewing 24 fps movie content on a 60Hz display monitor. You may consult search words “téléciné”, “flicker” and “adaptive sync.” on the Internet for additional information.

EXAMPLE: object in motion blurred while stationary object crystal clear

EXAMPLE: difference in clarity from images on a conventional LCD panel and another processed by TruMotion

EXAMPLE: image difference to demonstrate BLURRED / DE-BLURRED & DE-BLURRED ARTEFACTS

EXAMPLE: interlaced video capturing/transmitting still an intricate part of today's Broadcast TV standards.

For any VINTAGE LG SMART TV (prior to webOS6.0) please refer to the following on-screen menu path access to the TruMotion feature.  

TruMotion  (Smart )

[Vary with models]

Digital camera shutter speed effect designed at eliminating blurriness, object edge trailing effect

and residual images occurring especially during extremely fast-paced image sequence transition

while panel experiences difficulties keeping up.

Off

  - Turns TruMotion altogether “OFF” returning TV at processing images at 60Hz.

Smooth

  - Softens fast-moving picture transition.

Clear 

  - Makes fast-moving pictures clearer.

Clear Plus

  - Makes fast-moving pictures much clearer using backlight scanning method.

  - Clear Plus unsupported in 3D screen mode.

User

  - Can manually control juddering / blurriness.

  - De-Judder: Adjusts juddering on screen from sudden scene change in video.

  - De-Blur: Reduces the blurring effects of rapid motion on screen.  

Note: models relying on scanned backlighting only to achieve 120Hz will not feature any of

these aforementioned on-screen adjustments.
