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
for details.
2.
Go to the Display > Aspect Ratio menu.
3.
Press / to select an aspect ratio to suit the format of the video signal and
your display requirements.
