Dear experts,

I would like some advice on Dual monitor setup for users.

We would like to setup dual monitor for our accounting staffs, so that they can have a "bigger" viewing area (2xscreens). Of course I know we need 2 monitors, but how about video cards?

Is it simply install a second video card in the box, or do we need something more specifc? Heard about Dual Video Card (one card two outputs) - are they only useful when you run out of free slots in your box, or are they essential for dual monitor display?

Thanks for any input.

    You have a number couple of options, then best is to get a dual head graphics card, which are easy to find.

    Theres no way to advise a specific one, but for a cheap option

    2 graphics cards in one unit can cause problems, and is very much HW dependant

    The final option is to use "extra" external hardware to split the screens, never used but I'm guessing you'll see slowdown.

    I used 2 of these together in my PC to get 4 screens working. - superb value.  Dependent on your motherboard adding a card will either disable the onboard video or else you could still continue to use it in a 3 screen setup.

    Many of today's retail video cards already have two outputs (often there is a VGA and a DVI output, and even an additional S-Video output on the same card). I suggest before going out to buy a card look at the backs of your current PC's, they may already have such a card built in. If they have, all you need to do is go into the display properties of your OS (provided the 2nd monitor is already attached), and select to "Extend the Displays" (don't use "Clone", as that would just give you the same output on both monitors), and then you can normally move one display on top, or to the left, right or bottom, depending how you want the screen extended, and you can also say which monitor should be the main one- This of course will be slightly different from OS to OS, and also can change if you use a driver applet from the Graphic Card manufacturer.

    If you currently don't have such a card, just buy one that has 2 or more outputs, and look for outputs that best fit to your monitor (VGA, DVI etc.) If you only have VGA monitors you can usually connect an adapter to the DVI output of the card so you can also use the VGA monitor with such an output.
