Fit web videos to the left or right half of your monitor at any resolution. Ultrawide Video Halfscreen detects the usable size of the monitor containing Chrome, positions the browser on the left or right half, and expands the largest visible HTML5 video to fill the page area. It is useful for watching video while browsing, chatting, taking notes, or working on the other half of the display. Features: - Place video on the left or right half with one click - Adapt automatically to different resolutions and Windows display scaling - Detect the largest visible HTML5 video on the page - Detect the surrounding player controls and preserve the website's control bar - Keyboard shortcuts: Alt+Shift+Left and Alt+Shift+Right - Universal playback shortcuts: Space/K to play or pause, arrows to seek 5 seconds, and J/L to seek 10 seconds - Switch between complete aspect ratio and fill-and-crop modes - Exit and restore the previous Chrome window using Alt+Shift+Down - No user data collection, transmission, or sale Note: This extension uses a half-size browser window and an in-page expanded player. It does not invoke Chrome fullscreen, which would occupy the entire physical display. Some sites using specialized players or restricted cross-origin frames may not be supported.
