Panasonic PT-LB80NTU User Manual

If the projector is aligned non-perpendicularly to the 
screen, or if the projection screen has an angled surface, 
the keystone will be corrected automatically. Press I H 
to select the required setting.

 

ON:

Active

 

OFF:

Deactive

If you need to correct the angle of the projection even 
when the REALTIME KEYSTONE is activated, you can 
correct the keystone manually.

You can move the projected image for fine adjustment. 
Press I H to move horizontally and F G vertically. 
(Available with signals of VIDEO/S-VIDEO/RGB/YP

 

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. (Available with signals of RGB 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. (Available with 
signals of RGB/YP

 only)

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

 

Selectable options vary according to a input signal.

Q

The input signal will be projected in 4:3 ratio.

• 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.

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

than 108 MHz, the adjustment may not make a 
difference.

• DOT CLOCK needs to be adjusted before adjust the 

CLOCK PHASE.

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

than 108 MHz, the adjustment may not make a 
difference. See “List of compatible signals” on page 44.
