Adjusting the Screen Image
Manually Correcting Keystone Distortion
The projector is provided with an automatic keystone correction function
which detects the vertical angle of the projector and carries out keystone
correction automatically. If further correction adjustment is required after
automatic keystone correction has been carried out, use the [Keystone]
buttons on the projector's control panel to make the adjustment.
PROCEDURE
Projector Projector
If the bottom of the
image is elongated If the top of the
image is elongated
TIP
• When keystone correction is carried out, the projected image will
become smaller.
• If the images become uneven in appearance after keystone
correction is carried out, decrease the sharpness setting.

• Keystone correction can also be carried out using the configuration
menu. p.58
• If the value displayed in the gauge on the screen stops changing
when keystone correction is being carried out, it indicates that the
limit for keystone correction has been reached. Check that the
projector has not been set up at an angle which exceeds the proper
limit.
