change accordingly when you switch between
different input signals. Data (graphic) "PC"
presentations using mostly static images are
generally brighter than "Video" using mostly moving images (movies).
• The input signal type effects the options available for the Picture Mode. See
"Selecting a picture mode" on page 36
• The native display resolution is in a 16:9 aspect ratio. For best display picture
results, you should select and use an input signal which outputs at this resolution.
Any other resolutions will be scaled by the projector depending upon the 'aspect
ratio' setting, which may cause some image distortion or loss of picture clarity.

Selecting the aspect ratio

The 'aspect ratio' is the ratio of the image width to the image height.
With the advent of digital signal processing, digital display devices like this projector
can dynamically stretch and scale the image output to a different aspect than that of
the image input signal.
To change the projected image ratio (no matter what aspect the source is):
1. Open the OSD menu and make sure the Menu Type is Advanced. See
the menus" on page 28
2. Go to the Display > Aspect Ratio menu.
3. Press
your display requirements.
