    How can I use extended monitor set of two HP- EM869A [has Two connectors: one 15-pin mini D-sub analog VGA and one DVI-D (VGA analog or digital)] with my Gateway DX4840-37. I have one vga and one HDMI port on back panel. I do not want duplicate image on both monitors I want to run different application display separately on each monitors. What is the inexpenssive option with reasonably good quality of display

    Windows 7 allows for extending the desktop. That is the two screens appears a one extremely large one. By extending the desktop you can move windows across them. The programs are only shown on the monitor it is dragged to.

    I personally use this with VMplayer to virtualize Linux in windows * and display Linux on the second screen

    hdmi - ATI graphics card to feed three monitors
  • Mircea Chirea

    Assuming the monitors can take any kind of port and signal (digital/analog, DVI/HTMI, VGA, DisplayPort) so as to keep this only video card related:

    I'm looking to get a three-monitor setup using a single ATI Radeon HD 5XXX card. If I understand correctly the ATI hardware, the DVI and HDMI ports share the same video feed (since they're exactly the same digital video signal). However, what about VGA and DisplayPort?

    For instance take this video card from Gigabyte:

    Gigabyte video card with DVI, DP and VGA ports

    It has DVI, VGA and DisplayPort connectors. Can it feed three monitors?

    If not, what card should I get that can feed three monitors? I think it would need to have two DVI and one DP. The monitors are 1920x1080 and two 1280x1024.

    Here is another image. This one has a DVI, VGA and HDMI:

    Reading AMD's ATI Eyefinity Validated Dongles page I can confirm this:

    • A maximum of two VGA, DVI, HDMI or passive DisplayPort connections can be used.
    • Active DisplayPort is required for three or more connections.

    That means I can connector three monitors, two using the DVI/HDMI/VGA ports and the other using DisplayPort, either directly or via an active converter.
