42 in lcd as second monitor with ATI 2600hd

This is what Ive been able to find out.

I can get the 46" LCD to work full screen only if I set windows display properties to use one display .

ie) " show desktop 2 only "

If I set the display properties to "duplicate these displays" I cannot fill the large 46" screen edge to edge , even with catalyst control.

So based on all that I think its a windows issue.

Anyone else having this type of issue?

I have the same problem using CCC 9.4. A Microsoft person said this is a known problem which they are working on.

I get the same issue, I should be able to adjust the screen size and position using the Catalyst configure menu for the second monitor 42" LG however when I select this it defaults back to the home screen of Catalyst. It was fine in windows fista.
