DisplayOut is a new jailbreak application by Ryan Petrich, the developer of ProSwitcher, ActionMenu, and many other useful apps. DisplayOut mirrors your iPad screen on an external display such as a television.
This is a great app if you want to watch videos or pictures that are on your iPad on a TV.
DisplayOut supports the official Apple iPad VGA cable (other cables might work but haven’t been tested).
You can download this app from Cydia for $1.99 via the BigBoss repo.
