HP dx9000 Specifics The HP dx9000 touchscreen provides:  NextWindow optical imaging technology  HID compliant USB plug-and-play interfaceA maximum of two-touch recognition (recording no more than two contact points from fingers or stylus pens)  No pressure detection at the touch or contact points HP recommends Windows Vista® Business for HP dx9000. Windows Vista® recognizes single touch gestures automatically. Note   For two-touch recognition to work on Windows 7® , you will need to install NextWindow Windows® 7 touch screen driver. Simple twotouch gestures such as press and tap will work, but others like pan, pinch, zoom, and rotate may occasionally exhibit incorrect rotations on this platform. If your application primarily depends on a majority of rotate gestures, you may need to consider the next generation of the hardware which is designed for Windows® 7 and may better suit the purpose. Only single touch works on Windows XP®. See section Touch Support in Windows XP® for more details.
