This projector detects its own degree of tilt and corrects

the keystone distortion automatically.

OFF: Deactive

ON: Active

This projector detects its own degree of tilt and corrects

the keystone distortion automatically (“REALTIME

KEYSTONE”). However, keystone distortion may still

affect the images in some cases (e.g. when the projector

is tilted slightly and the tilt is corrected slowly by hand or

when the screen itself is tilted). In such cases, set

“REALTIME KEYSTONE” to “OFF” and correct the

vertical keystone distortion manually.

(S-VIDEO/VIDEO/COMPUTER/COMPONENT signals

only)

You can move the projected image for fine adjustment.

Press I H to move horizontally and F G vertically.

(COMPUTER signals only)

If you have interference patterns of the projected image,

which is sometimes referred to as moire or noise, you

can minimize it by pressing I H to adjust the clock

frequency.

(COMPUTER/COMPONENT signals only)

If you require further adjustment for the same reason as

the DOT CLOCK adjustment, you can fine adjust the

timing of the clock. Press I H to adjust.

(S-VIDEO/VIDEO/480i, 576i, 480p and 576p

COMPONENT signals only)

You can switch the aspect ratio manually when needed.

Press I H to cycle through the options.

Image Operation

NOTE:

• You can correct the distortion ± 30 degrees from the

plane. For a better quality image, installing the projector

with a minimum of distortion is recommended.

• The distortion of the Main menu screen is not

correctable.

• The result of the keystone correction will affect the

aspect ratio and the size of the image.

• You can correct the keystone distortion manually when

“REALTIME KEYSTONE” is set to “ON”.

However, when you turn on the power, the amount of

correction will be reset and “REALTIME KEYSTONE”

will function again if the tilt is different from the last time

you used the projector. If you correct the keystone

distortion manually when “REALTIME KEYSTONE” is

set to “OFF”, the amount of correction will be stored by

the projector even after the power is turned off.
