Is it possible to shorten the blank screen time?

The ideal performance for the client is to view each port in 5 seconds intervals,  and for a blank interval of 1-2 seconds. 

The blank time is only around 1-2 seconds when switching port manually at the front panel， while during auto scan it takes a lot longer. 

The delay in display is because that "Port ID" as below will be display first when you select auto scan. 

There is an option to disable Port ID display but this is not for Auto scan.
