If there’s a green line that just appeared on the bottom, sides, or the top of your LG TV, you might be really worried that your TV is broken. However, that’s actually probably a normal feature that’s part of your LG TV.
The green line that appears on the sides of your LG TV is something known as overscan. This is the overscan line that shows up when a broadcast, movie, or TV show doesn’t have enough information to fill the entire screen. You can fix this by setting the resolution of your TV to 16:9 or adjusting the image size to fill the entire screen.
The overscan feature isn’t the only thing that can cause lines to appear on your LG TV. Let’s take a closer look at overscan and a few other things that can be causing green lines to appear.
Why is there a Green Line on My LG TV?
Every LG TV has a feature known as Just Scan or Screen Fit. This is useful for ensuring that images fill up the entirety of the screen without having black spots that don’t have any visual information.
However, if a broadcast or a movie doesn’t have enough information to fill the screen, you’ll start to get these green or black lines at the edges of the frame.
These are known as overscan lines. This is simply your TV’s way of filling out the information that’s missing from the broadcast that you’re watching. These lines are perfectly normal and are not a sign of your TV being broken or damaged.
It’s worth pointing out that overscan lines can be black, white, or even static, in addition to being green.
The color of the overscan line doesn’t signal any different problem. It still all comes down to adjusting the image size on your screen and setting the resolution to 16:9.
How Overscan Works And Why It’s Actually Good
The core of this issue on LG TVs is a feature known as Screen Fit or Just Scan. This attempts to fit an image to the resolution that you sat on your monitor.
This allows you to watch videos that would otherwise be far too small to fully enjoy on a large LG television.
Those overscan lines are simply what your television does when it doesn’t have any information to fill the blanks.
In the same way that playing an album on a record player will sound wrong if set to the incorrect speed, footage on a television will look wrong if set to an incorrect resolution.
Screen Fit and just scan help you enjoy content on your full-size LG TV, but it might also require you to adjust the resolution and image size to get rid of those overscan lines.
How to Fix the Green Line on My LG TV?
Fixing over scanlines is about knowing what has caused them. The most obvious fixes are going to be adjusting your screen to a 16:9 resolution and then increasing the image size until it fills up the entire screen.
Green lines that appear inside of the image itself rather than on the edge could be a sign that your TV is experiencing a signal problem and needs to be turned off for 30 seconds while you check all of the connections.
Fixing Overscan Green Lines On a LG TV
Fixing the overscan lines on a LG TV is simple and easy. All you need to do is set your resolution to 16:9 and then increase the size of the image so that it extends just beyond the edge of the television.
This will force all of those over-scan lines outside of the visual field so you can enjoy your favorite movies and TV shows without any intrusive lines on the edge of the frame.
Fixing Green Lines Caused By Signal Problems and Glitches
If your green lines are showing up inside the image, there’s a good chance that your LG TV is experiencing a connection problem.
The first step to fixing these is to turn off your LG television and leave it off for 30 seconds.
While your LG TV is off, you should check all physical connections to ensure that your TV is securely plugged in and nothing is getting in the way of your connection.
