Thank you so much for your thorough & prompt reply. I don't have the Catalyst Control Center installed. Something in my system blocks the installation and I don't know what it is. I suspect it is the motherboard? 
Hmm?  
Now what? I can't test this answer.

Was hoping to avoid getting a new graphics card, as this one is very stable & runs cool. 

"Something in my system blocks the installation". Then the driver is not installed correctly. This sounds more like an Administrator rights issue?

No, it isn't administrative rights. It turns out that the installed driver is for an XP system. It was a bad install from the beginning. If I try to install any AMD or even uninstall this driver, the system freezes.

The registry reports it as the only ATI/AMD graphics driver ver 13.4 XP 64bit. This package also installed several system/chipset drivers. However, device Manager allows me to update the driver only (no CCC) which is at v14.3.

I have posted this newly discovered problem with AMD. 

It seems microsoft has a fix for the calibration problem? We'll see.

Thought I'd let you know that I have fixed the Catalyst Control Center problem and my screen is now the full 27" at 1080. It was, in part, an administrator problem. But not as simple as having administrative privileges. The ATI uninstaller never worked under any capacity.

I have not had time to try calibration again. And I have a niggly problem of the USB3 port used by the monitor showing up as an unknown in Device Manager. 

Thanks

Update: Calibration is complete. After running the MS FixIt solution the Calibration now offers a Reset, which allowed me to calibrate.

Now if only it really was calibrated! It is always off about a quarter of an inch. I suspect it is the USB 3 connection. Since Touch is controlled by the USB connection.  I have the latest drivers offered by motherboard (Asus) I am using the cables that came with the monitor.
The unknown device is: 

USB5534B

Any ideas?

TaDa! Update through DM worked it is now another Intel USB 3 Hub.

Thanks. 

How do I mark this thread as resolved?
