I just updated the CCC software to ver. 2015.0622.2137.37044.
Now my primary monitor has black bars around the desktop, which previously were not there. The CCC program does not have a setting to fix this. The monitor does not have a control to fix this. How do I fix this? Or how do I revert back to the previous software version?
The short answer that usually solves that problem is to find the Overscan slider and set it to 0%.
As you've not supplied any information about your system, that's all I can offer.
