How To Fix The Black Border On The Sides Of The Monitor?

To fix the black borders on the sides of your monitor, you can try the following steps:

1. Check Display Settings

• Windows:
  1. Right-click on your desktop and select Display settings.
  2. Scroll down to Display resolution and make sure it is set to the recommended resolution (usually the highest one).
  3. Under Scale and layout, ensure that the Display scaling is set to 100%.
• Mac:
  1. Click the Apple logo in the top-left corner and select System Preferences.
  2. Choose Displays and ensure the Resolution is set to Default for display.

2. Check Aspect Ratio and Resolution

• The black borders may appear if the aspect ratio of the monitor doesn’t match the resolution you’re using.
• If your monitor has a 16:9 aspect ratio, use a resolution that matches (e.g., 1920×1080).
• Set the resolution to the monitor’s native resolution for optimal performance.

3. Adjust the Monitor’s Display Settings

• Many monitors have built-in settings that can help eliminate black borders.
• Look for options like Aspect Ratio, Scaling, or Picture Size in your monitor’s OSD (On-Screen Display) menu.
• If the monitor is set to Wide or Auto scaling, try setting it to 1:1 Pixel Mapping or Full Screen mode.

4. Update or Reinstall Graphics Drivers

• Ensure that your graphics card drivers are up to date.
• You can update your drivers through the device manager (for Windows) or using manufacturer software (for Nvidia, AMD, Intel).
• Sometimes, a driver issue may cause improper display scaling.

5. Check for External Devices or Cable Issues

• If you’re using an HDMI, VGA, or DisplayPort cable, check that the cable is securely connected.
• Try using a different cable or port to rule out potential hardware issues.

6. Adjust the GPU Settings (for Nvidia/AMD)

• If you have a dedicated graphics card, go into the GPU control panel:
• Nvidia:
  1. Right-click on the desktop and select NVIDIA Control Panel.
  2. Under Display > Adjust desktop size and position.
  3. Set Scaling to Full-screen and adjust the Perform scaling on setting to either GPU or Display.
• AMD:
  1. Right-click on the desktop and open AMD Radeon Settings.
  2. Go to Display and look for Scaling Mode.
  3. Select Full Panel or Scale to Full Screen.

7. Check Monitor’s Input Source

• Ensure your monitor is using the correct input source. If it’s set to something other than the current input (like VGA when using HDMI), it could cause display issues.

8. Try a Factory Reset

• If none of the above works, consider performing a factory reset on your monitor. This option is available in the OSD menu of most monitors.

After going through these steps, the black borders should disappear if the issue was related to software or display settings. If the problem persists, it may be a hardware-related issue with the monitor itself.
