    You cannot use integrated graphics chip and add-on graphics card both at the same time.
    You need to fit a card which supports two monitors.
  2. what video card do you have? or do you have a laptop?

    you need to connect both monitor and tv to your video card if it has more then 2 slots normaly hdmi+dvi will work fine
