Eliminating flicker or blurring
(PHASE/PITCH)
When the monitor receives an input signal, the automatic picture
quality adjustment function of this monitor automatically adjusts
the picture position, phase, and pitch, and ensures that a clear
picture appears on the screen. For more information about this
function, see “Automatic picture quality adjustment function” on
page 18.
For some input signals, this function may not completely adjust
the picture position, phase, and pitch. In this case, you can

stored in memory and automatically recalled whenever the
monitor receives the same input signals.
These settings may have to be repeated if you change the input
