Turning on the “Just Scan” feature on your LG TV can significantly enhance your viewing experience by displaying images in their original aspect ratio. This feature uses 1:1 pixel mapping to ensure that the images fit perfectly within the screen’s borders, eliminating any stretching or distortion. However, activating “Just Scan” is not as straightforward as it seems. There are specific settings and technical nuances that you need to be aware of, especially if you’re dealing with different input sources like gaming consoles or laptops.

Here’s a quick how-to guide for turning on “Just Scan”:

  1. Press the Settings Button: Locate the settings button on your LG TV remote and press it.
  2. Navigate to Picture Settings: Scroll through the options until you find ‘Picture Settings’ and select it.
  3. Select Aspect Ratio: Within ‘Picture Settings,’ find and select the ‘Aspect Ratio’ option.
  4. Choose ‘Just Scan’: From the list of aspect ratios, select ‘Just Scan’ and confirm your choice.

By following these steps, you’ll not only activate the “Just Scan” feature but also optimize your LG TV for a better viewing experience. Whether you’re a tech-savvy individual or a beginner, this guide aims to provide you with a comprehensive yet straightforward roadmap for optimizing your LG TV settings.

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 images 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’s suggestions on the overscan amount.

Action safeTitle 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 is 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 a 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 is 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?’
