Windows 7: 4 Monitor Setup - Not Working - Help Plz

Hello Everyone,

After long deliberation I went ahead and bought new PC. The purpose is run 4 monitors with two grahics card, however so far I've no luck. I udpated the drivers, searched on Google and searched here.

Here is my configuration:
Intel i7 – 950
Gigabye X58A-UD3R
2 x Gigabyte HD 5570
Win 7 64 Bit

The two card are connected via bridge and under "Catalyst Contol Center" CrossFirex is enabled.

Right now only 2 monitor works and they both conneted to same graphics card. If I swap the cables then other 2 monitor works, which tell me that one card is not working at all. However both cards are detected under Device manager.

Any help is highly appreciated.



Regards

This might not help but your psu is a bit weak.

I am under the impression that 4 monitors will not work under crossfire. What are you trying to achieve? Do you want a single desktop to span 4 monitors or do you want to play games?

Have you tried 3 alone?

Thanks for taking time to reply everyone. I am not using this PC to play games. All I want is display stock market charts on all 4 screens.

No, I've not tried 3 monitors. I am using DVI and VGA connections only, haven't tried HDMI connection yet.

Please let me know if you have any suggestions

Do you have the correct drivers installed for crossfire. I have been reading the hotfix 10.9a driver fixes most issues for crossfire.

Motherboard/ Integrated Video Drivers for Windows 7 64-Bit edition

check you have all drivers installed

I've already updated drivers from that link. It seems that 1 card is not working even though it is detected in Device Manager

what about your bios?

Hi Prof,

I am not sure exaclty what you are referring to in BIOS. Can you please elaborate?

Have you tried it with the crossfire bridge off? I don't use ATI, but with Nvidia you can't use the second card for video output if the SLI bridge is connected, as it disables the outputs.
