Overview

Opens a multi-screen viewer in a new tab.

"Quad-Screen Video Viewer" A multitasking tool that lets you watch multiple videos simultaneously. Check out game streams, news, tutorials, and more all at the same time. This Chrome extension lets you watch up to four different videos simultaneously on one screen. It's ideal for those who want to keep up with multiple sources of information, such as game streams, breaking news, sports broadcasts, and online classes. Simply click the extension icon in your browser to open a new tab with four separate screens. Then, simply paste YouTube, Nico Nico Douga, Vimeo, or Dailymotion URLs into the respective input boxes and press the "Load" button. This simple operation dramatically improves your multitasking experience. This feature is also ideal for collaborative broadcasts where you want to view multiple perspectives simultaneously. Key Features - 4-Screen Simultaneous Playback: Watch up to four videos side by side. - Automatic URL Conversion: Automatically converts YouTube and Nico Nico Douga URLs into an embeddable format. - Layout Switching: Freely switch between a 4-screen grid layout and a main screen + 3 sub-screen layout. Lightweight and fast: We've eliminated unnecessary features to ensure a smooth experience. *Loading a video into a different frame while it's playing may cause the video to stop. This can be avoided by pausing the video and then loading it again. How to support the developer This extension is free, but we welcome your support to continue development and improvement.
