Adjusting the Clock Frequency of
the Input Signal
This is adjusted when light and dark vertical
bands appear on the projection screen of the
RGB and YPbPr input signal.
This is usually adjusted automatically at the
time of signal selection; however, this adjust-
ment is made when the automatic adjustment
cannot effectively make the adjustment.
Press the cursor (̆̄) buttons and align the cur-
sor with [Clock frequency], then use the cursor
buttons (̇̈) to remove the vertical bands and
render the screen brightness uniform.

Note:
*A light and dark striped pattern will
appear when there is lack of corre-
spondence between the input signal
and the pixel position of the projec-
tor. This is adjusted by the adjust-
ment of the clock frequency.
* When the image extends beyond the
screen or is smaller than the screen,
check whether the [Aspect] setting
is set to "Full."
