Second Monitor is detected as "Default VGA Monitor"

I have 2 CRT monitors (Dell D1025TM and E770p) on an ATI 3650 AGP card. The first monitor is always shown as what it is (ie. "DELL D1025TM") in the CCC Display Manager window. The second monitor is always shown as "Default VGA monitor".
I've gone through the display properties window and changed the driver for the second monitor to an E770p driver. But in CCC it still shows it as "Default VGA monitor" also even with manually adding the driver I still can't get the resolution or refresh range I know that monitor can do.
I've also switched the monitors around physically (as in switched the VGA plug-in cables not juggled the actual monitors :) ). It will then correctly show the E770p as the first monitor and the D1025TM as a "Default VGA monitor".
Is this a hardware limitation or software? If software is there a way to fix it?

Any advice would be appreciated. Thanks

If you're not running the latest drivers then update to the latest. If you still have the problem then it's a hardware limitation.

Unless you're running ancient Windows... you're running XP or Vista, right?

I've had the same issues, and I think it's the video card's hardware limitation. The RAMDAC for the 2nd output might not be handling the monitor's ID signal, so it reports it as default monitor. When I swapped the video card for a more expensive model, I didn't have this problem (both monitor reported correctly). Try with a different video card and see if you get the same result...

Jean-Luc: I'm running ATI drivers 9.4 hotfix for AGP cards on Windows XP SP3

razor: the Asus ATI 3650 is the best card I got. I had an old Ice-Q ATI 9800pro. Had the same issues.

I wonder if it's because my monitors are CRT with VGA cables not a LCD with HDMI or something better than VGA that could be the problem. Anyone know if that is the case?

Technically yes, that's the case, cause if you had your monitors on a different kind of connection you'd have a different video card, and it seems apparent that the issue here is your video card.

Here is the card I have. ASUS AH3650 SILENT I really don't think it is causing this issue. It could be the VGA adapters I'm using but I'm getting the correct ID for the first monitor just not the second. I'm going to switch the adapters when I get a chance and see if that works.

Again, thanks for the advice and any more would be appreciated.
