    That's exactly what a VGA splitter does, sends the same signal to two monitors, windows never sees the second display. You need to buy a card that supports dual display.
  2. Your card does not support dual display tech which is advertised today. You need a card which supports two displays but I doubt if it's available in the AGP category.
    So, most probably it's time you upgraded you rig.
    Seeing the specs for you rig would be interesting, since I used to have that card way long ago. :)
  3. You can get a dual monitor card for AGP, however you need to make sure that your card supports it. Many vendors will use the same chipset, but one may only have out output on the card and another can put 2 on.

    I installed several APG nVidia FX5200 cards with dual-outs and they run fine, you probably just had the wrong idea on how dual monitor displays work.

    Take a look here, http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709+600007850+600030348&QksAutoSuggestion=&ShowDeactivatedMark=False&Configurator=&IsNodeId=1&Subcategory=48&description=&Ntk=&CFG=&SpeTabStoreType=&srchInDesc= as you can see there are some cards with the same chip that have only one output, others have 2.
