Thanks for the info, A. I tried what you suggested and it worked. 
Although I now have a logo on the bottom right of the screen which says 
"AMD Unsupported hardware" which I would like to get rid of.

On the plus side, I can attach my HD TV and use that at its full 
resolution and have my smaller monitor at a suitable resolution for it.

I also found that I could not run the AMD Catalyst Control Center as 
root from the menu, I had to do it from CLI:

sudo amdcccle

At least it all works now and when I upgrade my monitor to the same size 
as my TV I will use both at 1920 x 1080.
