Ok... I have got a Radeon 9600 PRO which is currently hooked up to two monitors, which works fine.

However there is also onboard graphics which I know isnt the highest spec but would it work if I was to connect a third monitor to it?

If not can you recommend any graphics cards I could get so I could use that third monitor?

3 hmmm. Don't think so. You can add another one though.

Just try Most people have an AGP/PCIe card and then a PCI card.

I must say that I've never heard of two graphics cards working together on the same motherboard. I tried it once years ago and it didn't work. I think they will be trying to use the same resources and it'll come to conflicts or the one just won't work at all. The question is though, why do you want to use 3 monitors, does your software support splitting the screen over three monitors, I just know of splitting over two.
Yuo can try it anyway, I don't see anything blowing up or anything.

It works if you have SLI.

No SLI is needed.

I run 4 monitors using 2 cards, they're dual head.. one dsub and one dvi link.

WOrks just fine.

I can have a wallpaper for each one, i can order them as I need and they all run in their native. And i can play games on any of them.

I can hold my mouse or a window with mouse and move it from the left to the right over all the monitors as if it was one big one.

Floris can you explain me how did you connect 4 monitors?

You may not get an answer from a 2 year thread, but maybe someone will see this if you want more of an answer than the quote.

Feel free to start a new thread if you'd like.
