Adjusting the Screen Image
EMP-7850 Users Guide
When the projector has been tilted vertically, automatic keystone
correction is carried out so that images with no distortion are projected.
Automatic keystone correction is carried out approximately one second
after the projector is set up and projection starts. A vertical keystone
correction gauge appears on the screen while automatic adjustment is in
progress.
TIP
• The "Auto Keystone", "H/V-Keystone" and "Quick Corner"
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.
• "H-Keystone" and "Height" cannot be used at the same time.
• When keystone correction is carried out, the projected images will
become smaller. Use the zoom function to adjust the size of the
images if necessary. p.42
• If the images become uneven in appearance after keystone
correction is carried out, decrease the sharpness. p.76, p.79
Automatic keystone correction
TIP
• Automatic keystone correction is not carried out if "Rear Proj." or
"Ceiling" in the "Advanced1" menu is set to "ON", or if the
projection area has been corrected manually using the "Quick
Corner" function.
• If you would like to make further fine adjustments after automatic
keystone correction has been carried out, or if the projector is tilted
horizontally, you can carry out keystone correction manually.
p.47
• If you do not want automatic keystone correction to be carried out,
change the "Auto Keystone" setting in the "H/V-Keystone" sub-
menu of the "Keystone" command in the "Setting" menu to "OFF".
