What causes the Black bars to appear on the side of the monitor on Windows 10?
There are not many roots to this problem. It is generally due to the following factors —
- Your video adapter drivers. The video adapter on your system is responsible for the display of your system. In some cases, the drivers might not be operating properly after a fresh Windows install or a certain update which can cause the problem.
- Display settings. Sometimes, your display settings might change with a Windows update which results in the black bars.
Please make sure you follow all the solutions in order to ensure a quick workaround. The cause of the issue can vary depending on your machine, therefore, it is important for you to go through them all.
Solution 1: Change Display Settings
The most general cause of the black bars is your system’s Display settings. Sometimes, your display settings can change due to a Windows update etc. which results in the black bars on the side of the monitor. Therefore, in order to fix it, you will have to change your display settings. Here’s how:
- Go to Desktop, right-click and select Display settings.
- First and foremost, make sure your scaling is set to 100%. If you are using an old version of Windows 10, you will see a slide on the top of the Display panel. Make sure it is 100.
- If you are using the latest version of Windows 10, you will be able to see a drop-down list under ‘Scale and layout’. Make sure it is 100%.
- After you have rectified your scaling, click on the drop-down menu under Resolution and try changing the resolution to see if it fixes your issue.
- If you are on an older version of Windows, click on ‘Advanced Display settings’ and change the Resolution from there.
Also, if you are using a TV as your monitor, you can isolate your issue by changing the Aspect ratio of your TV to ‘Screen Fit’ or ‘Full 100%’ from the TV settings.
Solution 2: Reinstall your Video Adapter Driver
In some cases, your video adapter driver can be the guilty party which is causing the issue. Therefore, to eliminate such a possibility, you will have to reinstall your video adapter driver. Here’s how to do it:
- Go to the Start Menu, type in Device Manager and open it up.
- Expand the Display adapters list.
- Right-click on your Display adapter and select ‘Uninstall device’.
- Once the driver is uninstalled, restart your system so that the driver is installed again automatically.
- Check if it fixes your issue.
Solution 3: Install Video Adapter Driver Manually
At times, your issue might not be isolated by installing the video adapter driver automatically. In such an event, you will have to install your driver manually. Here’s how to do it:
- Open up the Device Manager.
- Expand the Display adapters list.
- Right-click on your video adapter driver and select ‘Uninstall device‘.
- After that, head to your manufacturer’s website and download the latest driver for your video card.
- Install the driver and reboot your system.
- Check if it helps.
