Adjusting the Screen Image
Correcting Distortion in the Projection Area
(Keystone Correction)
The projector is equipped with the following two functions for correcting
keystone distortion. Use whichever function is effective for correcting the
distortion.
• Quick Corner:
This correction function is used when both horizontal and vertical
keystone distortion occurs in the projection area to adjust the projection
area so that it fits the screen exactly.
• Vertical keystone:
This correction function is used when vertical keystone distortion occurs
in the projection area.
The keystone correction function lets you easily correct keystone
distortion that has occurred after moving the projector, simply by using
buttons on the projector's control panel. p.54
The Quick Corner function is operated using the configuration menu.
Correcting Keystone Distortion so that the Projection
Area Fits the Screen Exactly (Quick Corner)
TIP
• The "Quick Corner" and "V-Keystone" correction functions cannot
both be used together to correct keystone distortion. If you use one
function to correct keystone distortion, any correction that has been
applied using the other function will be cancelled.
• The larger the angle of tilt, the poorer the focus of the contours in
the projected images will become.
• If a large amount of keystone correction is applied, fine details such
as text characters and lines may go out of focus.
• Keystone corrections that have been applied using the keystone
correction functions are memorised even when the projector's power
is turned off. If you have changed the projection position or angle,
you will need to repeat the correction procedure.
TIP
If the angle of tilt when setting up the projector is within the range
given below, the Quick Corner function can be used to correct the
images.
· EMP-9300:Approx.40° vertically, approx.20° horizontally
· EMP-8300:Approx.45° vertically, approx.40° horizontally
However, the applicable angles will become smaller under the
following conditions.
• If the projector has been tilted both horizontally and vertically
• If an optional projection lens has been fitted
• If the lens position has been shifted or zoom has been set to "W"
