Correcting keystone
Keystoning refers to the situation where the projected image is noticeably wider at either the top or bottom. It occurs
when the projector is not perpendicular to the screen.
To correct this, besides adjusting the height of the projector, you will need to manually correct it following one of
these steps.
• Using the remote control
Press / on the projector or remote control to display the Keystone
correction page. Press to correct keystoning at the top of the image. Press
to correct keystoning at the bottom of the image.
• Using the OSD menu
1. Press MENU/EXIT and then press / until the DISPLAY menu is
highlighted.
2. Press to highlight Keystone and press MODE/ENTER. The
Keystone correction page is displayed.
3. Press to correct keystoning at the top of the image or press to
correct keystoning at the bottom of the image.
• You can correct the vertical keystones. However, their adjustment ranges are
limited in such correction.
• When the keystone adjustment is carried out, the adjustment value is indicated.
Note that this value doesn’t mean a projection angle.
• The allowable range of the adjustment value in the keystone adjustment varies depending on the installation conditions.
• Images may not be projected in a shape of a regular rectangle or with its aspect ratio 4:3 (EX240U)/16:10 (EW270U),
depending on the installation conditions of the projector and the screen.
• When the keystone adjustment takes effect, the resolution decreases. In addition, stripes may appear or straight lines may
bend in images with complicated patterns. They are not due to product malfunctions.
• Noise may appear on the screen during the keystone adjustment because of the type of the video signal being projected
and the setting values of the keystone adjustment. In such cases, set the keystone adjustment values in the range where
the image is displayed without noise.
• When the keystone adjustment is carried out, the image may not be displayed correctly because of the type of input
signal.
