Is your Samsung TV not showing full screen? Users experience This common issue when trying to watch content on their Samsung TVs.
Sometimes you’d even notice streaming platforms like Netflix or YouTube not showing full screen.
The problem can occur because of many reasons.
But not to worry, we will look at these reasons and tackle them together.
Why is my Samsung TV not full screen?
There are various reasons why Samsung TV cuts off the picture on your screen.
Incorrectly set aspect ratios and not knowing how to change resolution on Samsung TV can lead to issues.
1. Over-scanning
If you notice that the edges of the image are cropped or not fully displayed on the screen, then your TV is over-scanning.
Overscan was more prevalent in older CRT televisions, but it can still occur in some modern TVs, particularly when receiving certain signals or using specific display settings.
2. Wrongly Set Aspect Ratio
The aspect ratio determines the proportional relationship between the width and height of the image displayed on your TV.
If the aspect ratio is set incorrectly, it can result in black bars or cropped edges on the screen
3. Faulty Cables
Faulty cables can cause issues with your SamsungTV display, including your Samsung TV not showing full screen.
Are you wondering how? A damaged cable can result in a weak or inconsistent signal reaching your TV.
This can lead to issues like pixelation, or loss of portions of the image, including not displaying the full screen
4. Issue with the Source Device
If you are screen-mirroring your phone or PC or Apple AirPlay you may need to find out if there’s a setting you can adjust on your device to fix the issue.
A lot of users have noticed this issue when mirroring their devices. It could happen due to aspect ratio differences or wrong mirroring settings.
