1. Obtain MENU window and move highlight
cursor up and down through the menu
with the or button.
2. Adjust parameter value for the selected
item with the or button. For items
that call for a separate bar graph, first
show the bar graph with the “ENTER” or
/ button, then adjust parameter value
with the or button.
• RGB/YPBPR/DVI signals
• Composite/S-video signal
CLK PHASE (for RGB signals only)
Adjust clock phase after you are finished with dot
clock adjustment.
Clock phase adjustment allows the user to minimize
visible noise with the or button.
HORIZONTAL POSITION (H.POSI)
button: Shifts the picture to the right.
button: Shifts the picture to the left.
VERTICAL POSITION (V.POSI)
button: Shifts the picture upward.
button: Shifts the picture downward.
VIDEO SIZE
(Vaild for composite video/S-video only)
button: Increases picture size.
button: Reduces picture size.
DOT CLK
(Vaild for RGB signals only)
Fine, regular patterns on the screen may be disturbed
by fine stripe noise called moire. Dot clock adjustment
allows the user to minimize this moire.
KEYSTONE
Keystone distortion can be corrected only along either
horizontal bound of the picture:
V. LINEARITY
After you are finished with keystone adjustment,
adjust vertical linearity with the or button.
Vertical linearity is not adjustable if no correction was
made to keystone distortion.
Note
• A noise may not disappear when adjusting the
dot clock or clock phase at UXGA signal mode.
• Clock phase is adjustable for each of R, G,
and B signals. Final parameter values are
saved to memory.
• Clock phase adjustment is not available for
digital RGB signals.

Note
•
Keystone distortion can be corrected to ±20˚ of
the angle of tilt for the projector. However, the
greater the correction amount,the more the picture
quality will deteriorate, and the harder it will
become to achieve a good level of focus. To obtain
the best picture quality, set up the projector and
screen in such a way that the amount of keystone
correction required is as minimal as possible.
• The picture size will also change when
correction of keystone distortion is carried out.
