Your graphics card must have two monitor outputs and you will need a good processor as well. The other option is a SLI/Crossfire setup but that is a messier and more expensive option since you need to buy two GPUs.
This would not be a software solution. This configuration would require specialized hardware as well.
Dual monitors will only work if your graphics card can support it. It cannot run off of a motherboard (then again i could be wrong) The motherboard supports dual monitors out of the box when running Windows XP. I'm using two LCD monitors, one is connected to the VGA port and the other one is connected to the DVI port, it works like a charm.
The best ergonomic setup for an L-shaped desk with two monitors includes positioning the monitors at eye level, using an adjustable chair with proper lumbar support, keeping the keyboard and mouse at elbow height, and ensuring there is enough space for movement and proper posture.
http://support.microsoft.com/default.aspx?scid=kb;en-us;307873 This article indicates that WinXP supports up to 10 monitors. Many video cards will support 2 monitors. If you install two such cards, then you may connect 4 monitors. Add video cards as long as you have empty PCI slots in the PC.
Interlaced monitors.
Comment from the person who asked - I'm researching computer hardware for a new computer I'm constructing, and in my past experience, two monitors has always been a great plus. I would like to have the two monitors line up horizontally; however, two 20" widescreen monitors is just a bit pricey for my purposes, and so I am aiming for a widescreen monitor and a normal resolution (4:3 aspect ratio).
give me two examples of hardware
If you mean two TYPES of monitors then there are FLAT SCREENS and CRT monitors. Flatscreens are good because they save space and energy. CRT monitors take much more space but give better colours.
i don't know and want it's answer...lol
what is an operating system? and give two examples
One word: hardware
If you want to work with two monitors you will need a monitor switch box or a second video card to connect two SVGA monitors to one computer. You'll need Windows XP or Mac OS X or newer.
