Stereoscopic 3D Viewer is a Chrome add-on developed by llyzs that allows users to view stereoscopic 3D images on passive 3D monitors. With this add-on, users can easily convert side-by-side and over-under stereoscopic images to row-interlaced format, enabling them to be viewed directly through passive 3D monitors.

One of the key features of Stereoscopic 3D Viewer is its user-friendly interface. Users can simply right-click on any image and use the context menu to choose one of the supported stereoscopic 3D formats. Alternatively, users can also move the mouse pointer over any image and utilize the keyboard shortcuts to convert the image. The keyboard shortcuts can be configured via the "chrome://extensions/configureCommands" settings.

However, it is important to note a couple of limitations. Firstly, the browser zoom factor must be set at 100% for the add-on to work properly. Secondly, some websites that use dynamic HTML to display images might not function correctly with Stereoscopic 3D Viewer.

Overall, Stereoscopic 3D Viewer is a useful tool for those who want to view stereoscopic 3D images on passive 3D monitors. It provides a convenient way to convert images and supports various formats, making it accessible to a wide range of users.
