NOTE      •  Be  sure  to  check  jack  type,  signal  level,  timing  and  resolution 
before connecting this projector to a computer.
•  Some  computers  may  have  multiple  display  screen  modes.  Use  of  some  of 
these modes will not be possible with this projector.
• Depending on the input signal, full-size display may not be possible in some 
cases. Refer to the number of display pixels above.
•  Although  the  projector  can  display  signals  with  resolution  up  to  UXGA 
(
 600x  00),  the  signal  will  be  converted  to  the  projector’s  panel  resolution 
before  being  displayed.  The  best  display  performance  will  be  achieved  if  the 
resolutions of the input signal and projector panel are identical.
• Automatically adjustment may not function correctly with some input sign\
als.
•  The  image  may  not  be  displayed  correctly  when  the  input  sync  signal  is  a  composite sync or a sync on G.
