The table below summarizes the amount of delay incurred for a selected native

in that mode until the sync detection is
manually refreshed.
Press

to refresh the sync detection process for the selected
native input. This procedure enables the

Auto
mode.
~
In
Auto: Minimum Delay
mode, the button is grayed out.
