1. Open the OSD menu and go to the
DISPLAY > Aspect Ratio menu.
2. Press Enter.
3. Press / to select an aspect ratio to suit the format of the video signal and your

About the aspect ratio
1. Auto
: Scales an image proportionally to fit the projector's native resolution in its
horizontal width. This is suitable for the incoming image which is neither in 4:3 nor
16:9 and you want to make most use of the screen without altering the image's aspect
ratio.
2. 4:3: Scales an image so that it is displayed in the center of the screen with a 4:3 aspect
ratio. This is most suitable for 4:3 images like computer monitors, standard definition
TV and 4:3 aspect DVD movies, as it displays them without aspect alteration.
3. 16:9 (PA500S/PA503S/PA503SP/PA500X/PA503X/PA503XP/PA503SB/PA503XB/
PA503SE/PA503XE): Scales an image so that it is displayed in the center of the
screen with a 16:9 aspect ratio. This is most suitable for images which are already in
a 16:9 aspect, like high definition TV, as it displays them without aspect alteration.
4. 16:10 (PA503W): Scales an image so that it is displayed in the center of the screen
with a 16:10 aspect ratio. This is most suitable for images which are already in a 16:10
aspect, as it displays them without aspect alteration.
