Arrangement Tab No Longer Visible in Display Preferences

I have a mini display to HDMI adapter that I have been using for the past three or four months to connect my MacBook Pro to my 32" Samsung LCD TV, and up until recently it had been working fine, but suddenly there have been issues. One day I was attempting to set my laptop to display the same image on the TV that is on my laptop display. To do this I assumed that I would simply have to go to the arrangement tab and select "mirror displays". This, however, did not work. Instead no image appears on the TV and I can no longer select the arrangement tab in my preferences. When I connect my computer to the TV the screen flashes blue for a second, as it always did when I attached it to a TV, but nothing shows on the television, except for a message saying "Mode Not Supported". I have tried everything I can think of to troubleshoot this problem. I have tried multiple HDMI cords, mini display to HDMI adaptors, different TVs, and different MacBooks, and nothing has worked. The same thing has happened with every combination, with no solution. If anyone knows how to fix this I would be very grateful. I assume I need to find some way to reset the display settings, but I cannot figure out how to do that.
