I recently was offered a job that requires dual monitors. how do I set up both to work??

Just plug in the second video card. install it. and go to ur display properties and enable it (right click on desktop, properties) You might have to enable it in the bios. for my machine I click delete a few times when the pc first starts up (within a second or two of the power button). this gets you into the bios. i have to find in the bios what says (init display first). I have to set the pci as the primary display, and by result, agp as secondary. the bios, and windows load then shows up on the pci card. in windows i set the agp as primary. email if you need help can you tell me about this buisiness! as they said, duel monitors video cards work. a cheap pci video card for second display works and is cheaper if you do not need high proformance output on second monitor

The simplest way is to add a dual monitor card like the Matrox DualHead2Go (instead of using the on-board VGA. Check the guide here: http://www.cyberinkdesign.com/dual_monitors.htm

make sure your video card is dual tuner compatible and tehn extend your dektop to both monitors under display properties by enabling the second screen and clicking extend my desktop

You have not said what your video card/source is. First you need a video card that will drive two monitors separately. If you do not have two video outputs either VGA (blue connector) or DVI (white connector) then you need a new video card that has two outputs. These are very common and pretty cheap these days. Install the video card, and attach both monitors. Install the drivers for the video card. Then: Control Panel > Display Properties > Settings tab. You will have a image of two screens. 1 is the monitor with your taskbar etc. 2 is probably grayed out and the 2nd monitor is not working yet. If the 2nd monitor is not working or it is showing an exact copy of the 1st, click on the 2 screen in the window and then the "Extend my Windows desktop . . ." Click "Apply" The 2nd monitor should now be active and show your desktop background, but without the taskbar and icons etc.. Make sure that it is at the right resolution and colour depth. Drag the 1 or 2 monitor around in the window so that the positions correspond to the physical relation of the two monitors. If you get confused which is which, click the "Identify" button and you will get a big 1 and 2 displayed on the relevant screens. Click Apply to try things out. When you are happy with everything click OK and enjoy your two monitors!
