NOTE:
Some signals may take time to display or may not be displayed correctly.
NP61/NP41: The Auto Adjust function does not work for component and video signals.
NP62/NP52: The Auto Adjust function does not work for component/video signals, and the Viewer source.
If the Auto Adjust operation cannot optimize the RGB signal, try to adjust HORIZONTAL/VERTICAL, CLOCK and PHASE manu-
ally. (→ page 56, 57)
If performing the Auto Adjust function does not correct image positioning, vertical stripes (banding) or horizontal noise, per-
form the [HORIZONTAL], [VERTICAL], [CLOCK] or [PHASE] function from the menu to optimize the image. (→ page 56, 57)
Performing  the  [HORIZONTAL],  [VERTICAL],  [CLOCK]  or  [PHASE]  function  will  store  the  adjustment  values  of  the  currently 
projected source into the projector’s memory.
The  next  time  the  same  source  (same  resolution,  horizontal  and  vertical  frequencies)  is  projected;  the  projector  will  call  up 
from memory the stored values for the source.
To  clear  the  stored  adjustment  values,  select  the  [RESET] →  [CURRENT  SIGNAL]  or  [ALL  DATA]  from  the  menu  to  reset  the 
adjustment values.
