You can extend the cord. Its in two parts, a standard HDMI cable carries the video and touch screen data. That can be extended with an HMDI cable from Best Buy or similar. I normally tell people to get a standard cable and a double female adaptor. The USB part carries only the power supply for the Touch 50. If you extend it you need to use an "active" USB cable. "Active" means it carries the power. You don't necessarily need to extend it because you can use a phone charger or 12 volt power USB outlet to supply the power instead.
