Tip :
• When keystone correction is carried out, the projected image will become smaller.
• Procedure to follow if using both horizontal and vertical keystone correction:
1. With the front adjustable foot retracted, set the projector so that it is fully horizontal.
2. Extend the front adjustable foot to adjust the angle as necessary.
3. Adjust the vertical keystone distortion until both sides of the picture are vertical.
4. Adjust the horizontal keystone distortion until the top and bottom edges of the
picture are both horizontal.
• The keystone correction settings are memorized, so that if you change the position or
angle of the projector, you may need to readjust the keystone correction settings.
To return a previous keystone correction to the initial setting, carry out the following
operations.
To initalize vertical keystone correction: While holding down the [Sync +] button,
press the [Sync -] button for 1 second or more.
To initalize horizontal keystone correction: While holding down the [Tracking +]
button, press the [Tracking -] button for 1 second or more.
• If the images become uneven in appearance after keystone correction is carried out,
decrease the Sharpness setting. (P.63)
• Keystone correction can also be carried out using the projector setting menu. (P.69)
• If you carry out both horizontal and vertical keystone correction, the correction range
will become smaller than it would be if only one type of correction was carried out.
• If the value displayed in the gauge on the screen stops changing when horizontal or
vertical keystone correction is being carried out, it indicates that the limit for
horizontal or vertical keystone correction has been exceeded. Check that the projector
has not been set up at an angle which exceeds the proper limit.
• If either the E-Zoom, Effects or P in P functions are used at the same time as horizontal
or vertical keystone correction has been carried out, a message may appear on the
screen if these functions are used when the keystone correction amount is near the
limit. It may not be possible to use the E-Zoom, Effects or P in P functions if this
happens. In such cases, re-adjust the projector position so that the amount of keystone
correction required is reduced.
• The limit value for keystone correction will vary depending on the video signal being
input.
