My POS screen doesn't look like the demo I saw online.

Press Ctrl-F6 in the POS screen. Click on Transaction Screen tab, then look in the lower section titled Window, Size. Note the size of your monitor display, then enter one of the following settings. 

1024 x 768 -- this is the minimum suggested resolution for Manager and POS

Height: 12
Width: 12
Height: 14

800 x 600 -- this is the minimum resolution for POS operation
Height: 10
Width: 10
Height: 12

The demonstration we provide online is run in 1024x768 mode. If your screen resolution is something other than 1024x768 or 800x600, you can adjust with these setting as desired.

NOTE: If you do not know your screen resolution settins, right-click on a blank area of the Windows Desktop and select Properties, Settings (or Screen Resolution on Windows 7).
