You can now use a second screen on your IT5000, laptop or PC (not Mac compatible). Simple plug in the adapter into a spare USB port and install the software and you can then run a second monitor. This is ideal for running a slideshow on a second screen. The second screen can be upto 10 meters from your IT5000 or PC by using our A-A USB Extension cables (5m). No additional power is required as this is taken from the USB port.
