We are rolling out Polycom VVX 450. The main display has 3 columns or zones for lack of a better term. "Left" Columns has the 6 line keys, Middle column has the time and date, and the right column has the other 6 lines. The middle zone is rather large and cuts off the line descriptions for the left and right line keys. Is there a way to adjust this? You can turn off the date/time but the middle "column" is still there. Seems like a big waste of screen area.
