THIS SOLVED MY PROBLEM!
Make sure USB display is set on projector's menu > extended. Secondly set the projector to USB source. Third I suggest to uninstall and re-install the USB driver and install the latest version which is 1.50 and follow this instructions.
Go to the Hard drive, application, USB display, tools and run the uninstall. Reboot, run ver. 1.50 and after it is installed, reboot one more time.
USB display driver download.
