The projector identifies the video ID 
(VID) embedded in the image signals 
and displays the image by automatically 
switching the screen sizes between 4:3 
and 16:9.
4:3
When standard signals*1 are input, the 
pictures are displayed without changing 
the aspect ratio.
When wide-screen signals*2 are input, 
the pictures are displayed with the 
aspect ratio converted to 4*3.
16:9
When standard signals*1 are input, the 
pictures are displayed with the aspect 
ratio converted to 16:9.
When wide-screen signals*2 are input, 
the pictures are displayed without 
changing the aspect ratio.
16:10This format is for 16*10 input sources, 
like wide screen laptop.
*1:  Standard signals are input signals with an aspect 
ratio of 4:3 or 5:4.
*2:  Wide-screen signals are input signals with an 
aspect ratio of 16:10, 16:9, 15:9 or 15:10. 
Note
If an aspect ratio which is different from the aspect ratio  z
for the input signals is selected, the pictures will appear 
differently from the originals. Be careful of this when 
selecting the aspect ratio.
If using this projector in places such as cafes or hotels to  z
display programs for a commercial purpose or for public 
presentation, note that adjusting the aspect ratio or using 
the zoom function to change the screen pictures may 
be an infringement of the rights of the original copyright 
owner for that program under copyright protection laws. 
Take care when using a function of the projector such as 
the aspect ratio adjustment, zoom function, etc.
If conventional (normal) 4:3 pictures which are not wide- z
screen pictures are displayed on a wide screen, the 
edges of the pictures may not be visible or they may 
become distorted. Such pictures should be viewed as 
with an aspect ratio of 4*3 in the original format intended 
by the creator of the pictures.
