							Correcting  Keystone  Distortion
You  can  correct  keystone  distortion  using  one  of  the  following  methods.
•Correcting  automatically  (Auto  V-Keystone)

When  you  correct  keystone  distortion,  the  projected  image  may  be
reduced.
Correcting  automatically  (Auto  V-Keystone)
When  the  projector  detects  any  movement,  for  example  when  it  is  installed,
moved,  or  tilted,  it  automatically  corrects  vertical  keystone  distortion.  This
function  is  called  Auto  V-Keystone.
When  the  projector  remains  still  for  about  two  seconds  after  it  detects
movement,  it  displays  a  screen  for  adjustment  and  then  automatically
corrects  the  projected  image.
The  following  conditions  are  necessary  to  correct  the  projected  image  using
Auto  V-Keystone.
Correction  angle:  approx.  30˚  up  and  downa
•Auto  V-Keystone  works  only  when  Projection is  set  to  Front from
the  Configuration  menu.
