You will need another video adapter. https://www.google.com/search?q=usb+video+adapter&num=50&rlz=1C1_____enUS438US438&espvd=210&es_sm=93&source=univ&tbm=shop&tbo=u&sa=X&ei=v94xU7rqM6W_0AGzioCgCg&ved=0CCoQsxg&biw=1200&bih=1792
The option for duplication of the screen is not a hardware related it depends upon the platform/software you are using. Windows from vista(Grid vista) onwards provide a built-in feature to handle multiple screen. I suggest you to update your video drivers and try running the windows file integrity scan this will diagnose if there any configurations files are corrupt.
When you press power button press continues F8 key then you see safe mode and other menu enter in "ENABLE VGA MODE'
then go to dispaly property and settings then change screen resolution to 1024.768
then apply and ok.

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF
THERE IS NO VIDEO INPUT SIGNAL. IN ORDER FOR THIS
MONITOR TO OPERATE PROPERLY, THERE MUST BE A VIDEO
INPUT SIGNAL.
This feature is designed to conserve electrical energy by reducing power
consumption when there is no video input signal present.when there is no
video input signal present.When there is no video input signal, this monitor,
following a time-out period,will automatically switch to an OFF mode. And the
LED will turn orange. This reduces the monitor's internal power supply
consumption. After the video input signal is restored, full power is restored
and the display is automatically redrawn. The appearance is similar to a
"Screen Saver" feature except the display is completely off. The display is
restored by pressing a key on the keyboard, or clicking the mouse. Lenovo ThinkVision E54 User Manual
