Seeing the edges of your screen cut off can be incredibly frustrating. Whether you’re gaming, watching videos, or simply trying to work, a display that doesn’t show the full picture hinders your experience. This issue, known as overscan, can stem from various sources, ranging from incorrect display settings to driver problems. Let’s delve into the common causes and how to rectify this annoying problem.
Understanding Overscan: The Culprit Behind Cropped Edges
Overscan is a technique used by older televisions to ensure that the entire image fills the screen, even if the signal is slightly imperfect. Historically, broadcast signals were prone to variations, and overscan compensated for these by displaying an image larger than the visible screen area. This meant that the outermost edges of the image were intentionally cut off.
While overscan was necessary for older analog TVs, modern digital displays generally don’t require it. In fact, overscan on a digital display often results in a blurry or cropped image, which is exactly what we’re trying to avoid. The key to fixing this problem is often disabling overscan or adjusting the display settings to properly fit the screen.
Pinpointing the Source: Common Causes of Cropped Display Edges
Several factors can lead to your display cutting off the edges of the image. Identifying the correct cause is the first step toward finding a solution.
Display Settings and Overscan Options
The most frequent culprit is incorrect display settings, especially overscan settings. Many TVs and monitors, even modern ones, still have overscan enabled by default or offer it as an option. This is a remnant of the older technology and can cause significant cropping when connected to devices like computers or game consoles.
Within your display’s menu, look for settings labeled “Overscan,” “PC Mode,” “Just Scan,” “Full Pixel,” or similar terms. Disabling overscan or enabling a “PC Mode” or “Just Scan” option is often the simplest and most effective solution.
Graphics Card Driver Issues
Your graphics card’s driver plays a crucial role in how your display renders images. Outdated, corrupted, or incorrectly configured drivers can lead to a variety of display problems, including overscan.
Ensure that you have the latest drivers installed for your graphics card. Manufacturers like NVIDIA, AMD, and Intel regularly release driver updates that improve performance, fix bugs, and enhance compatibility with different displays. Keeping your drivers up-to-date is a fundamental step in troubleshooting display issues.
Resolution and Refresh Rate Mismatches
An incorrect resolution or refresh rate can also cause the display to cut off edges. Your display has a native resolution, which is the resolution it’s designed to display optimally. Using a different resolution can lead to distortion or cropping.
Similarly, using an unsupported refresh rate can cause problems. Check your display’s specifications to determine its native resolution and supported refresh rates, and then configure your computer’s display settings accordingly. Matching your display’s native resolution and supported refresh rate is essential for a clear and accurate image.
Connection Problems: HDMI and Other Cables
The type of connection you’re using to connect your device to your display can also influence the image quality and whether overscan is applied. HDMI is the most common connection for modern displays, but different HDMI versions and settings can affect the image.
Sometimes, the display might misinterpret the HDMI signal, leading to overscan. Experimenting with different HDMI ports on your display and ensuring that your HDMI cable is securely connected can sometimes resolve the issue. Try a different HDMI cable to rule out a faulty cable as the cause.
Operating System Settings: Display Scaling and Zoom
Your operating system’s display settings can also contribute to the problem. Features like display scaling or zoom can inadvertently cause the image to be cropped or distorted.
Check your operating system’s display settings to ensure that the scaling is set to 100% or the recommended level. Adjusting these settings can often resolve minor cropping issues. Pay close attention to scaling settings, especially if you’ve recently changed them.
Game Console Settings
If you are experiencing this issue on a game console like PlayStation, Xbox or Nintendo Switch, the problem may lie within the console’s display settings. Each console has options to adjust the screen size and aspect ratio, and these settings might be configured incorrectly.
Navigate to the display settings on your console and look for options like “Screen Size,” “Display Area,” or “Aspect Ratio.” Adjust these settings until the entire image is visible on your screen. Refer to your console’s manual for specific instructions on adjusting display settings.

Why are the edges of my screen cut off, even though everything seems connected correctly?
Overscan is often the culprit when you experience cut-off edges on your screen. Historically, TVs were designed to display content with some extra border to account for variations in broadcast signals. This “overscan” ensured that the entire image filled the screen, even if the signal was slightly distorted. However, with modern digital connections like HDMI, overscan is often unnecessary and can lead to portions of the image being cropped off.
Many displays and devices (like gaming consoles, set-top boxes, and even computers) have overscan settings that can be adjusted or disabled. Check the settings menu of your display and any connected devices for options related to overscan, picture size, or screen scaling. Look for terms like “Just Scan,” “Full Pixel,” “1:1 Pixel Mapping,” or “Screen Fit.” Disabling or adjusting these settings should resolve the issue.
How do I know if overscan is the actual problem and not something else?
A quick way to test if overscan is the issue is to look for common elements that should be visible across the entire screen. For example, if you’re using a computer, check if the Windows taskbar or macOS dock is partially hidden. Similarly, if you’re playing a game, observe if the on-screen display elements, like health bars or mini-maps, are being clipped at the edges. Consistent cropping of these elements strongly indicates an overscan problem.
Another reliable method is to use a test pattern specifically designed for overscan calibration. You can find these patterns online by searching for “overscan test pattern” or “TV calibration images.” Displaying this pattern on your screen will visually highlight any areas being cropped off due to overscan, making it clear whether adjustment is needed.
Where do I find the overscan settings on my TV?
Overscan settings on your TV are usually located within the picture or display settings menu. The exact location and terminology may vary depending on the TV manufacturer and model. Common names for this setting include “Picture Size,” “Aspect Ratio,” “Screen Fit,” “Display Area,” “Just Scan,” “Full Pixel,” or “1:1 Pixel Mapping.”
To find these settings, navigate to your TV’s main menu, often accessible via a button on your remote control labeled “Menu,” “Settings,” or a gear icon. Look for sections related to picture settings, display settings, or aspect ratio control. If you’re unsure, consult your TV’s user manual or search online for specific instructions for your model.
What if the overscan settings are already disabled, but the edges are still cut off?
Even with overscan disabled on your TV, the source device connected to it might still be applying overscan. Check the display settings on devices like gaming consoles (PlayStation, Xbox, Nintendo Switch), streaming devices (Roku, Apple TV, Chromecast), and set-top boxes (cable or satellite boxes). Each device may have its own overscan or display area settings that need adjustment.
If the source device is a computer, ensure the graphics card drivers are up to date. Outdated or corrupted drivers can sometimes cause display issues, including overscan. Additionally, check the display settings within your computer’s operating system. You may need to adjust the screen resolution or scaling settings to properly fit the screen.
How does screen resolution affect the appearance of cut-off edges?
Incorrect screen resolution can create the illusion of cut-off edges, even when overscan isn’t the primary issue. If the resolution is set too high for the display, some parts of the image may be truncated or appear distorted. Conversely, if the resolution is too low, the image may appear blurry or stretched, making the edges seem less defined.
To ensure proper display, always set the screen resolution to the native resolution of your monitor or TV. This information is usually listed in the display’s specifications or user manual. On a computer, you can typically adjust the screen resolution through the display settings in your operating system. For TVs, the resolution settings are usually found in the picture or display menu.
My computer is connected to the TV, and the edges are cut off. What should I do?
When connecting a computer to a TV, several factors can contribute to cut-off edges. First, verify that the graphics card drivers are updated to the latest version. Outdated drivers often cause compatibility issues with TVs, leading to incorrect display scaling or overscan. Additionally, ensure the correct input is selected on the TV, as some inputs may have different default settings.
Next, check the display settings within your computer’s operating system. Set the screen resolution to the TV’s native resolution, and look for options related to scaling or display area. Many graphics card control panels (like NVIDIA Control Panel or AMD Radeon Settings) offer specific settings for adjusting the display output to fit the TV screen. Experiment with these settings until the image fills the screen correctly without any cut-off edges.
Why does overscan exist if it causes problems with modern displays?
Overscan originated in the era of analog television broadcasting. Variations and imperfections in the analog signal meant that the very edges of the transmitted image were often unreliable and potentially distorted. Overscan was implemented to ensure that these problematic edges were hidden, providing a consistent and visually appealing viewing experience.
While digital signals are generally more stable and reliable, overscan remains a default setting on many TVs and devices for historical reasons and to maintain compatibility with older content that was originally produced with overscan in mind. Manufacturers often include overscan settings to cater to users with older equipment or those who prefer a more traditional TV viewing experience.
