Still sounds like a fault with the driver. With both cables going to the same monitor, the driver should recognize that it is the same monitor, and not display both, or it should disable the "lesser", analog connection, I would think.

It is possible that there is a driver for the monitor that would resolve this issue, too.

Perhaps you should install the current ATI/Win 7 driver for that card. Even so, both cables to the same monitor might still be a situation not recognized by the driver.

You might contact the ATI folks for advice, but I suspect they will recommend not having both cables hooked up to the same monitor.

It is very likely that the older Win XP drivers simply were not able to detect the situation. Was the XP PC using the exact same video configuration?

At least you've resolved the issue. MA3 is not the problem, but it did show the symptom.

Good work on troubleshooting, Dale.
