The TouchIT 55" LCD Duo Pro Interactive LCD with integrated PC is one of the world's first truly integrated touch-based LCDs on the market today. The TouchIT LCD Duo Pro is built to last with an aluminium frame and a 4mm tempered glass finish (5mm on 65" and above). Utilising the latest optical touch technology, the TouchIT LCD Duo Pro is capable of dual inputs under Windows 7. By using your finger or a stylus to touch the LCD, you have a mouse at your 'fingertips' to communicate your ideas. There is no need for any special pointing device or stylus. Simply touch the screen for both left and right click mouse functionality, enabling you to control your computer directly from the display.
