Does Vista support triple screens? What type of graphics card is needed?

Does Nvidia Geforce have a card that support three screens?

guess you could go for the 'gamers' option if you cannot find a gfx card that has three outputs...

... that is to get a mother board that supports SLI and buy two gfx cards (giving you 4 outputs, 2x2)

Not sure if its supported in vista thou

Vista offer better multi screen support than XP. There are a number of ways to approach this, and it depends on the computer set-up you have.

1. If MB supports it {only a few do} use the SLI option, though this is as much about combining the horsepower for games as proving multiple monitors.

2. Use a Matrox three head card

3. Add a PCI video card to the system, assuming here you're already using PCIe 16 as main card. It is recommended that the card is from the same manufacturer and preferably range as the master. This can be tricky, sometimes this will work straight out of the box, with the BIOS understanding the multiple cards, other times it an be tricky {sorry}.

Can you tell us what the set-up is presently?

What will it be used for? Whether or not you need the horsepower of high end 3D cards will make a big difference in what options are available.

If you're a gamer, you'll need to consider some SLI options like the other suggested but there are much cheaper options if it's just for general PC work.

There's a lot of focus on gaming. For the record, the only way you're going to get dual+ screens working in current games (with the exception of some flight simulators) is to use one of those Matrox triple head to go. This will limit you to, IIRC, 1024x768 per screen. So far both Nvidia and AMD/ATI don't support multi-screen SLI/Crossfire setups when in games.

Now, if you're looking for productivity, your best bet is to get two cards. They can even be PCI based as long as they have the required DVI/VGA connectors for your monitors. For any serious resolution, say at and over 1280x1024 I'd definitely recommend going with DVI because when you start getting to that point you really do see the differences.

Also of concern is getting the same manufacturer. Not necessarily the same board, but the same GPU manufacturer. I.E. don't mix AMD/ATI and Nvidia cards. It's doable per se, but in reality it's probably going to cause headaches.
