How do I attach 3 monitors to a single computer. I can use the video card I have for Dual monitors.?

I don't want clones I just want 3 monitors for separate windows|||Your question is a bit vague - as you don't say what OS you are using.



It seems that you are saying that your current card is a dual head. Generally you can attach a second card - or use the on board video on your Mb.



Once you have set up the cards (the HW and the resolutions, etc) - you may have to set particular interrupts etc, unless the OS will set them up for you automatically.



Within the OS, there is usually a way to set one as the 'default' and there are ways to move various windows onto various monitors.|||Either replace your dual head card with a quad head card (Kind of expensive) or get another video card that will fit in your system.



If you get another video card then get one that has the same family chipset as your current dual head card. It means that the drivers will play nicely together. This is a requirement for Vista.|||Windows XP, Windows Vista, and OS X all allow you to install a second video card. The second card would let you run a third monitor, once you enable it through the display control panel (in Windows.) OS X should make it available automatically.|||If you using windows xp or 2000/2003

On Board Display card with add one Dual Display card like nvidia NVS 285 or matrox g450. Here you can get options for separate windows in single system.|||You cannot get 3 monitors out a of a duel card. Also it is ebst I have found to disable any on board video when using cards (don't mix).



You can use two dual cards (most systems have the PCI or PCIE slots to add 2 cards (check this); or get a quad card and use 3 leads; (this is more $ and you will find it cheaper to add just one card.)



Nvidia Ge Force is a good series of cards that start out economical to crazy depending on how much you want. Be carefull if you have Vista. Lots of cards out there are not certified for Vista and do not work or work very well.



Good luck|||Assuming that you are using Windows XP or Vista...



To attach a third monitor, you will of course need a third connector. If you do not have one on your PC, then you will need to purchase a second video card to add to the computer.



Once installed, you should be able to go into the Control Panel and the Display icon. Under the Settings tab you will be able to configure the three montiors. To get different displays on each, you need to "extend" the desktop across the other two monitors.



Depending on the brand(s) of your video card(s), you might have an extra icon in the Control Panel, or an extra tab in the Display settings for configuring your monitors.
