UltraWideo is a cross-browser extension developed by dvlden that allows users to manipulate the aspect ratio of videos to fit their entire screen. With its unique functionalities, this extension stands out from others in its category.

One of the key features of UltraWideo is its compatibility with all video streaming platforms and embedded videos. Whether you're watching videos on YouTube, Netflix, or any other platform, this extension works seamlessly. It can even handle multiple direct or embedded video players on a single page without affecting other videos.

This extension is not limited to UltraWide monitors; it can be used by anyone who wants control over the video aspect ratio. If you're tired of watching videos with black bars, UltraWideo allows you to resize the video to fill your entire screen, providing a better viewing experience.
