May be you have been facing issues with how your screen has been displaying images and all you want is to bring it to an end. Turning on the ‘just scan’ mode stops this issue. Am I diving right in? What is ‘just scan?’ How do you turn it on? Stick around to learn and much more, but first lets understand the roots of the problem.
What is ‘just scan’ on LG TV
By default, your television is set to display the wrong resolution.
Let me explain it to you.
LG tv has two main display modes, ‘overscan’ and ‘just scan.’ Overscan which in most cases is the default display setting, is a behavior of the screen in which parts of the images appear outside of the visible parts of the screen.
Take a look at the below images,
The green box is no longer visible in the second image, and the squares on the corner adopt a rectangular shape. Unfortunately, there is no standard specification on the amount of image that can be overscanned. Besides, the title safe modes require more margin than the action safe modes, which means that the appearances will differ.
Below is a table showing the BBC suggestions on the overscan amount.
|Action safe||Title safe|
|14:9 (displayed on 16:9)||3.5%||10.0%||5.0%||15.0%|
|4:3 (displayed on 16:9)||3.5%||15.0%||5.0%||17.5%|
Let’s say it point blank, the overscan mode not only changes the appearance but may also distort the image. Fortunately, this error can be corrected using the ‘just scan’ mode.
Just scan is behavior in LG television that uses 1:1 mapping to allow the pictures to be displayed only within the border. Thus, it shows the original image without stretching it, distorting its properties such as resolution.
In other words, ‘just scan’ shows clearer and sharper images which are not something to compromise.
With that said, do you want to have higher-quality pictures while watching your favorite movie? If yes, how do you get your LG TV to ‘just scan?’

LG has two main picture display modes, overscan and ‘just scan.’ In most cases, overscan is the default mode. However, this display mode stretches the images out of the screen and, in some instances, corrupts the picture quality.
Overscanning can be corrected by setting the ‘just scan’ picture aspect ratio that uses the 1:1 mapping technique. Hence, it does not stretch the image resulting in higher quality images.
You can get your LG TV on ‘just scan’ aspect ratio by navigating to settings, picture settings, aspect ratio and selecting it on the pop-up screen.
