Check the Device Manager for any ! or ? (missing driver) and ensure the contacts of the adapter are clean.

toggle between screen display modes by holding function and f8 together- there may be a few seconds delay between each settings so be patient
if that fails , then goto display settings and in advanced you should be able to select the displays you want.
