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

 signals only)

You can switch the aspect ratio manually when needed. 
Press I H to cycle through the options.

• 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.

 

 

• If the projecting signal’s dot clock frequency is higher 

than 100 MHz, the adjustment may not make a 
difference.

• DOT CLOCK needs to be adjusted before adjusting the 

.

• If the projecting signal’s dot clock frequency is higher 

than 100 MHz, the adjustment may not make a 
difference.

• CLOCK PHASE is available with PC signals and the 

following COMPONENT connection.
