I Recently bought a adapter which plugs into the VGA port on my Computer, and gives me 2 VGA ports to plug 2 screens into, however when i plug them in, it just clones the screens, i want to have a main and then extend one, and every time i click extend on the connect a display window on windows 7, it just does nothing, and also on the connect a display page, it is only showing up 1 screen not 2.

Anyone have any ideas what the problem is??
Thanks for any Reply
