What Ultrawide Video Extension Does

Ultrawide Video Extension is a browser add-on that removes the black bars from the sides of videos and stretches the picture to fill a wider screen. When you watch a movie or show that was filmed in a standard aspect ratio (like 16:9), the extension detects those black bars and expands the video to use more of your monitor's width. This works best if you have an ultrawide monitor — one that is noticeably wider than a standard rectangular screen — but you can also use it on a regular monitor if you want the video to take up more space.

The extension does not read videos, change their quality, or store them anywhere. It only changes how the video appears in your browser while you watch. Once you close the tab or turn off the extension, the video goes back to normal on your next visit.

Key Takeaways

  • Ultrawide Video Extension works by detecting black bars on the sides of videos and stretching the image to fill more of your screen width.
  • You install it from your browser's extension store (Chrome Web Store for Chrome, Firefox Add-ons for Firefox) in the same way you would any other extension.
  • The extension has settings that let you choose which websites it works on, how much it stretches the video, and whether to keep the original aspect ratio or stretch it fully.
  • Some videos will look distorted if you stretch them too far, so you may need to adjust the settings per video or turn the extension off for certain sites.
  • The extension works only in your browser — it does not affect videos you watch in standalone apps like Netflix's desktop process or YouTube's app.

Installing Ultrawide Video Extension

The installation process depends on which browser you use. If you use Chrome, Brave, or Edge, go to the Chrome Web Store, search for "Ultrawide Video Extension," and click the blue "Add to Chrome" button (or "Add to Brave" or "Add to Edge" depending on your browser). The extension will install automatically and appear as a small icon in your toolbar.

If you use Firefox, go to Firefox Add-ons, search for the extension, and click "Add to Firefox." The process is identical — you do not need to restart your browser or change any settings. Once installed, the extension is active when ready and will start working on supported video sites.

After installation, you may see a popup asking for permission to run on certain websites. Click "Allow" or "Allow on all sites" depending on what the extension asks. If you want to limit it to specific sites, you can change these permissions later in your browser's extension settings.

Adjusting Settings for Different Videos

Click the extension icon in your toolbar to open its menu. Most versions of Ultrawide Video Extension show a slider or set of buttons that control how much the video stretches. A setting of 0% means no stretching — the video stays as it was filmed. Moving the slider to 50% or 100% stretches the image progressively wider. Start at a lower percentage and increase it only if the video looks good stretched.

Some versions include a toggle for "aspect ratio preservation," which keeps the video from looking squashed or stretched unnaturally. If you turn this on, the extension will expand the video width but also adjust the height slightly to keep people and objects from looking distorted. If you turn it off, the video will stretch to fill the full width of your screen, which can make faces look wider or objects look flattened.

You can also set which websites the extension works on. Open your browser's extension settings, find Ultrawide Video Extension, and choose "Allow on specific sites" if you only want it active on YouTube, Vimeo, or other video platforms. This prevents it from trying to stretch non-video content or interfering with other websites.

Using the Extension While Watching Videos

Once the extension is installed and configured, you do not need to do anything special to use it. straightforward open a video in your browser as you normally would. If the video has black bars on the sides, the extension will detect them automatically and explore your chosen stretch setting. The video will expand to fill more of your screen width.

If the stretched video looks wrong — if people's faces look too wide, or if the image looks pixelated — click the extension icon again and lower the stretch percentage. You can adjust it in real time while the video is playing. Some videos will look better at 50% stretch, while others may look fine at 100%.

If you want to turn the extension off temporarily for a specific video, click the icon and select "Disable on this site" or toggle it off. The video will return to its original appearance. You can turn it back on the next time you visit that site.

When the Extension Does Not Work

Ultrawide Video Extension works only in your web browser. If you watch Netflix, Disney+, or YouTube through their standalone desktop apps, the extension will not affect those videos because it only controls what happens inside your browser window. You would need to watch through the website version instead.

Some video players have built-in protections that prevent extensions from changing how they display. YouTube, Vimeo, and most major streaming sites allow the extension to work, but smaller or custom video players may not. If the extension does not seem to be working on a particular site, try refreshing the page or checking whether the site's video player is supported.

Videos that were filmed in an ultrawide format already (like some YouTube videos shot specifically for ultrawide monitors) may not have black bars to remove. The extension will not add content that is not there — it can only stretch what exists. If a video is already filling your screen, the extension will have nothing to do.

Troubleshooting Common Issues

If the extension icon does not appear in your toolbar after installation, it may be hidden. Click the puzzle-piece icon in your browser's toolbar (usually in the top right), find Ultrawide Video Extension in the list, and click the pin icon next to it to make it visible. This moves it to your main toolbar where you can access it easily.

If videos are stretching but look distorted or pixelated, lower the stretch percentage in the extension settings. Very high stretch values can make the image quality worse, especially on lower-resolution videos. A setting of 50% to 75% often looks better than 100% stretch.

If the extension stops working after a browser update, try disabling it and re-enabling it. Go to your browser's extension settings, find Ultrawide Video Extension, toggle it off, wait a few seconds, and toggle it back on. If that does not work, uninstall and reinstall the extension from your browser's extension store.

Frequently Asked Questions

Does Ultrawide Video Extension work on all video websites?

It works on most major sites like YouTube, Vimeo, and many streaming platforms, but some sites with custom video players may not support it. You can test it on any site by opening a video and clicking the extension icon to see if it detects black bars. If nothing happens, that site's video player may not be compatible.

Will stretching videos make them look bad?

It depends on how much you stretch and what the video contains. Stretching 25% to 50% usually looks acceptable, especially if you have an ultrawide monitor. Stretching 100% can make people look wider or objects look distorted. Start low and increase the percentage only if the video looks good to you.

Can I use this extension on my phone or tablet?

Most versions of Ultrawide Video Extension are designed for desktop browsers only. Mobile browsers like Chrome on Android and Safari on iPhone have limited extension support. You would need to check your phone's browser to see if it allows this extension, but most mobile devices do not support it.

Does the extension slow down my browser or use a lot of memory?

Ultrawide Video Extension is lightweight and should not noticeably slow down your browser or use significant memory. It only processes video when you are actively watching, and it does not run in the background when you are not using it. If you notice your browser running slowly, the extension is unlikely to be the cause.

What happens if I uninstall the extension?

All videos will return to their original appearance when ready. The extension does not save any changes to videos or your browser — it only affects how videos display while it is active. Uninstalling it is completely reversible, and you can reinstall it anytime from your browser's extension store.
