There are a number of styles available for your touchscreen.  

When you open the Engage Touch Console, navigate to the Settings section and click on the drop down box (as illustrated below), the preview will change.  If you click on the preview box then a larger preview will appear.  Click this larger preview again to go back to the previous view.

When you have selected the style that you would like, go to the Tools section and click on Sync to save your changes.
