What is the benefit of having two computer screens on one computer?

It is basically like having an extra screen area on one screen. It allows you to have:\n\nthe full-screen views of two applications at once, one on each screen, or\n\none full screen view spread across the two monitors. \n\nThe latter is convenient for instance when you have 100 columns on an Excel spread sheet. You don't want those columns to be squished into one monitor.

It's possible to do a dual-display setup with your computer but there are some things you should know.\n\n* AGP cards are exclusive so it definitely won't share with your on-board video.\n* Some systems are designed to disable on-board video when another video card is inserted (PCI or AGP).  It's hard to tell if your system will do that.\n\nNo problem though, you just need to buy a video card with two video outputs.  I'm familiar with nvidia cards and I know for certain that dual-display is supported in the software so any nvidia card would work as long as two VGA outputs are present on the card.  If you plan to connect to one CRT and one LCD with DVI connector, you can use this card then (see picture):\n\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16814121184\n\nIf you are doing two CRTs, however, you'll need something like this where they include a DVI-to-VGA adaptor:\n\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16814168002\n\nYou can also look for dual-VGA video cards like this one but I'm not familiar with ATI products and how easy it is to set it up:\n\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16814161150

It allows you to switch between all of the applications you have running.  It is important to HOLD the Alt key.. while you only TAP on the Tab key... that will allow you to easily select the application you need.  This is great to use if your computer is freezing and you lose mouse functionality.

Using Bootcamp or Virtual PC, you CAN work on multiple applications at once.\n\nBeauty of multi-tasking.

I think you are allowed to have it on two computers. But Norton has LiveUpdate, which communicates with the Norton website. That may or may not pose a problem. I think you can try it but if you have more than two computers you may run into problems.

not unless you log in on seperate cpu's....can not be log in more than once on the same screen .... if you open new windows for each log-in i think it will accomplish what you are looking for

if you have a lcd monitor there is no reason to have a screen saver. the images no longer get burnt into the monitor like they did in the old days of computing

You need two video cards installed, if you have a regular desktop machine.  For laptops/notebooks with an external display port, you can hook up a second monitor to the port, and use both that and the notebook monitor (you will have to make a change to your graphic settings, depending on your installed video card).\n\nFor a desktop, install a second video card.  Open Display in the Control Panel, and click the monitor icon for the monitor you want to use in addition to the primary monitor.  Select Extend My Windows Desktop onto this Monitor checkbox, then Apply, then Ok.  If you don't see that checkbox, your card may not support multiple monitors.  Make sure you have hardware that supports multiple monitors before you purchase any equipment.  You might wind up having to buy to video cards (one to replace your original card, and one to support the additional monitor.).

High-end rigs use two video cards, but not to display two different things, like all of the people who posted above me think you're wanting to do.  The two video cards (the process is called SLI) display half of what you see on the screen at any one time.  For instance, card #1 always displays lines 0-1024, while card #2 always displays lines 1-1023.  That's faster, for gaming, but it's not really needed today.\n\nHere's what I would recommend you buy, for gaming, if you got lots of money to burn: http://www.newegg.com/Product/ProductList.asp?Submit=ENE&N=2010380048+1067920129&Subcategory=48&description=&srchInDesc=&minPrice=&maxPrice=  Any of those cards will do any of the newest games, at high resolutions, with high framerates.  If you don't have $300 for one card (BTW, SLI would cost more, since you'd need to buy two cards, and wouldn't necessarily give you more performance, if you bought 2 slower cards), anyway, here's what I would get (these are the best value for the money): http://www.newegg.com/Product/ProductList.asp?Submit=ENE&N=2010380048+1067918888+1069609641&Subcategory=48&description=&srchInDesc=&minPrice=&maxPrice= or: http://www.newegg.com/Product/ProductList.asp?Submit=ENE&N=2010380048+1067920131+1069609641&Subcategory=48&description=&srchInDesc=&minPrice=&maxPrice=  \n\nIf you're only wanting to run "dual desktops", just buy yourself any of these cards, you'll save yourself quite a bit of money: http://www.newegg.com/Product/ProductList.asp?Submit=ENE&N=2010380048+1069609642&Subcategory=48&description=&srchInDesc=&minPrice=&maxPrice=\n\nedit: No, your Dell isn't SLI compatible.

You can extend your desctop on the second monitor if you have one. This way the second monitor will not display just a copy of the primary one, but there can be placed individual windows there and etc. The only limitation is that you cannot have different background picture on each of them :)

Conserves energy, supports very high resolutions, portable, sexy.\n\nNote: Viewing angle is still a trouble..... you don't have that problem in CRT monitors. The picture becomes negetive & colour changes when we increase the viewing angle of a TFT screen.

If you are connecting multiple monitors to a computer then you would need to purchase an adapter or switch that allows you to have more monitors.

Do you speak of two screens, a separate desktop background for each, or one screen with a split background?\n\nEither way you'll need an image modification program, like Photoshop for instance.\n\nSay you have two screens. Make a composition in Photoshop that is the size of both monitor's resolution combined. For example, both screens are 800 x 600. Therefore, the document must be both widths combined, being 1600 x 600.\n\nPut a guide down the middle and put whatever you want in the space. Now save this image into your My Images folder, or place where you can find it.\n\nGo to your display menu. Start --> Control panel --> Display. Or a shorter way to get there, right click on the desktop and then select Properties.\n\nOnce in the display,  choose your background and set it to Tile (must be Tile!). If you made it the right size, it will fill in both screens as one big image. If you painted the left half purple, the left screen will be purple and so on. Use this method for one seamless vista as well.
