Triple Monitor not working with 5850

Hello guys, I have an XFX 5850 and I'm currently running 2 monitors on DVI. I'm trying to add a 3rd monitor on the DisplayPort using a DVI to DP passive adapter. I do not need Eyefinity for gaming, I just want to use 3 monitors for working. Whenever I try to turn on the 3rd monitor by extending my desktop to it, it tells me I need to disable a non-primary monitor to have the 3rd one enabled. I've tried to search online for solutions, I even tried to put my primary running on the DisplayPort. Do you guys have any suggestions?

I have 2 monitors with native DVI support and 1 Monitor with only VGA, for the VGA one I have a cable that goes from VGA to DVI, I hope this information helps on troubleshooting my issue.

Thank you in advance

You need an active displayport adapter
Dell and Sapphire make them for sure this i know.
Around $65 i'm sure others make them as well

Eyefinity will not work with a passive adapter. You need to have an active adapter if you want to use three monitors.

I'm not trying to run eyefinity, I just want to have 3 monitors for my desktop to have 3 browsers open at the same time without needing to alt-tab. Will the active adapter still give me the error that says, "To extend the desktop, a desktop or display must be disabled". I am able to enable the 3rd monitor but it required me to turn off one of my already on monitors only letting me run 2 monitors at a time.

The active adapter will allow you to run all three monitors at the same time. That's what Eyefinity is.

Isn't eyefinity being able to combine all 3 monitors to have 1 wide monitor to game on all 3 monitors? I don't need to game on the 3 monitors, just want to run 3 monitors in normal

Using all three monitors as one big one is just one way to set up an Eyefinity setup. You can also use the three monitors on their own.

The active adapter is a solution to a hardware limitation in Eyefinity, not a software limitation.

Bought a passive VGA to DP and it works fine now, even with eyefinity
