Solve : Two Cards, Two Monitors?

1.	Solve : Two Cards, Two Monitors?
Answer» I have two video cards, one's an nVidia 5700 and the other an ATI Radeon. I have two monitors, one plugged into each card. Both video cards are seated, updated, and are working properly. The monitor on my nVidia (my primary card) works fine, but on my Radeon (my secondary card) the monitor isn't detected. If anyone has any suggestions I'd appreciate it. ThanksGo to Control Panel, Display, and select the Settings tab. You should see two rectangles representing the two monitors. Do you see them? Click the one marked 2 and then check the BOX for "Extend my Windows DESKTOP onto this monitor." Click Apply and OK.

Yes, prior to the two-card config. I was using just the nVidia card. There are (going of photograph memory) 5-6 PCI slots on my motherboard, the ATI is in the slot just below my nVidia. The computer was built from scratch, I do not know the make and model.I asked what PCI slot because it can make a difference. I recently installed a second video card in a Sony VAIO desktop. I initially installed the card in the second PCI slot below the AGP slot. Even though Device Manager showed the second display adapter, the display was not working right. I removed the card in put it in the top PCI slot. That worked. Usually, the top PCI slot is the best choice and you already have the card in that slot. So, I don't know whether trying other PCI slots would be worth trying, but it might be. On my home machine, I have two cards installed, and my PCI card is not in the top slot. Also, do you have any documentation on your motherboard? If so, check it for info on BIOS settings related to video. Try running a diagnostic tool called dxdiag.
