3rd monitor detected by WinXP but no signal

[stalemate]

Hello,
I'v got a ATI radeon HD3650 card with 1xDVI out and 2xDisplayports. I've connected a monitor to each of these ports.
However, whe I use HW manager to see that the displays are connected, they show up, and i n Catalyst Control center, they also show up, but only 2 at the time. So I can switch between the different monitors, but not all three at the time. What am I missing here..?

Tri-Monitor (or more) setups are only available from Eyefinity-enabled ATI graphic cards (HD5xxx series). You cannot display on more than two monitors at any given time with your current card.

Not any more, there is an Nvidia card that can do four screens at the same time.

OP might just asking for three monitors to be working at the same time independently, not necessarily one big desktop covering all three monitors.

i think he's got seeing any two of them solved, and wants three.

If not, hopefully he'll clarify.

As Twoboxer says, I can enable two at the time, they're all available in CC Center, but I'm not able to have image on more than two, but if it's not supported, I'm out of luck.

Thanks for the reply guys!
