Currently, the Decile Hub data room viewer includes a static navy blue frame that cannot be removed, even in fullscreen mode. This is a limitation of the current platform design, and there is no built-in way to expand the document view beyond this frame without downloading the file and opening it locally. The frame is part of the user interface to maintain consistent navigation and controls, but it can restrict viewing space and may not feel intuitive.

For now, the best workaround is to download the file and open it with your preferred local application for a full-screen, unobstructed view. For further feedback or feature requests, consider reaching out via [Decile Hub Support](https://decilehub.com/base/8-hub_support).
