Landscape TV Out is a new iPhone hack developed by Daniel Juhn which let you view apps fullscreen with fast framerate on your TV using a TV out cable. Landscape TV Out is based on TVOut by ashikase.
TVOut by ashikase should be uninstalled first (jp.ashikase.tvout). TV Out settings and documentation is installed to Settings, under TV Out. Enable in Settings to get started!
