UltraWide Video is a free Chrome extension developed by James. Designed specifically for wider than average screens, this program allows users with 21:9 aspect ratio monitors to play online video content and fit the screen properly in fullscreen mode.

The extension offers two main features to enhance the fullscreen experience. Firstly, it includes an aspect ratio mode that enables users to toggle on the fly with the keyboard shortcut ctrl+alt+c. This mode ensures that videos are displayed without any black bars and are properly scaled to fit the entire screen.

Secondly, UltraWide Video provides a crop mode, which also can be toggled with ctrl+alt+c. This mode focuses on removing any unnecessary elements from the video frame, providing a clean and immersive viewing experience.

In addition to these features, the latest update has brought more stability and compatibility with various video players. Whether you're watching videos on YouTube, Netflix, or HBO GO, UltraWide Video ensures that wide aspect ratio videos are displayed correctly in fullscreen mode.
