English-19 Tag3 Auto Adjust Automatically adjusts the Image Position and H.Size settings and Fine settings.
(Analog input only) Press “SELECT” to activate Auto Adjustment.
Signal Adjust Determines when the auto adjustment is activated automatically.
(Analog input only) The choices are “SIMPLE” and “FULL”. Press “Left” or “Right” to select.
Auto Adjust Level Determines the automatic adjustment level for Auto Adjust. The choices are “SIMPLE”,
(Analog  input  only) “FULL” and “DETAIL”. Press “Left” or “Right” to select. Refer to the below table.
A-NTAA SW The Advanced No Touch Auto Adjust function is able to recognize new signals even when
(Analog input only) neither the resolution nor the refresh rate has changed. If several PCs are connected to
the monitor, and each transmit very similar (or even the same) signals in terms of
resolution and refresh rates, the monitor recognizes that there is a new signal and
automatically optimizes the picture without the need for any action on the part of the user.
OFF: A-NTAA is disabled.
ON: If a change in signal is detected A-NTAA will adjust the monitor to the optimal settings
for the new signal. If no change in the signal is detected then A-NTAA does not activate.
The screen will be blank while the monitor optimizes the signal.
OPTION: Functions the same as ON, except that the screen does not go blank when the
monitor makes adjustments for changes in signal, allowing the monitor to display the new
signal faster. When using an external switching device to connect 2 or more PCs to the
monitor, using the ON or OPTION settings is suitable.
