We use the adapter to connect our laptop to our tv, for some crazy reason my husband selected to make the tv the main monitor, now the is no desk top image, no tool bar, no image at all showing on the tv when the adapter is connected. When connecting the adapter it acts as it always did except now there is no image in the tv. How can I change the laptop back to the primary monitor?
right click desktop . select the pc screen , make it #1
