This is slightly used for demo only and was on a pro series 42" Panasonic display and is in good condition. 

Excerpt from manufacturer below:


Ideal for business meetings and classrooms, the 2700 series allows executives and teachers to create dynamic, engaging presentations.  The large, clear screen can be seen by everyone in the room.  Presenters can efficiently move through interactive material just by touching the screen, eliminating the distraction of a keyboard.

Actions such as tap, pinch and swipe allow you to select, resize and pan.  These intuitive gestures allow you to advance through photo albums, play media, navigate through your files and browse the Internet.

The overlay uses sophisticated optical imaging technology and a robust design to provide touch solutions suitable for high-traffic, public environments.  This model connects through a HID-compliant USB interface and is plug-and-play.  The system integrator or end user can install the 2700 over a monitor, without the need to open the display's enclosure and possibly void warranties.

The 2700 is Microsoft Windows 7 compatible and multi-touch capable with a simple driver download.  Zoom in or out by moving two fingers closer together or further apart.  Spin an object by rotating a finger around another, and right-click by holding one finger on your target and tapping the screen with another.
