Hi everybody, I have a client that has a strange dual monitor issue. He has a pretty new Dell with one lcd monitor (main) and an additional older flat panel he uses to extend his desktop to. Both are connected to a dual vga card he had added to his build when he ordered the PC. (Windows 7) For some strange reason the screens flip-flop back and forth on reboot, with his main desktop moving over to the 2nd monitor. The only way he can get them to switch back once booted is by swapping the connections in back. We have tried setting the dual monitor settings repeatedly, it won' stick. Now he says its gotten worse and the main desktop hops over to the other randomly. Ideas???

Have you tried this:
(assuming Win7 since you said "pretty new")
right click on desktop > Select 'screen resolution' > there should be 2 monitors in the appearance section. You can drag and drop the monitors, meaning put monitor 1 on the left or right, and vice versa. Should fix problem.

Did that to death, even changed to resolutions to match, just won't stay. Updated the drivers too, weird.
there is no control panel, maybe because Dell installed the card as an option, I thought that was odd, only windows display settings, its a nvidia, I forgot which model.

does the video card have a DMS-59 connection with a 2 x vga yoke?
Maybe the yoke is bad.
Did you install the monitor drivers? maybe windows is getting confused about which "default monitor" is which.

I ran updates on both, which it actually did install new drivers, but the second older driver did not stay, it rolled back to a generic driver on reboot, curious. I never opened the case on it, yet.

He bought the monitor on ebay, unknown brand, you may be right, win 7 doesn't get it right. The resolution doesn't go quite as high as his main monitor, and seems sketchy when I tried to match them up. Wish he had another to test it with.
