Airtame is a device that is capable of streaming video files from your computer to external screen. You can see more information here: Audio & video streaming
However, various factors need to be considered. If streaming movies is the main use-case, perhaps, Airtame is not the right device. It is designed for business/education oriented environments where main focus is presentations, occasional videos and similar use-cases related to meetings and classes. In case watching movies is the main use-case, there are other devices that can do this more conveniently.
