Menu Option Description
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.
NOTE: Only supports HDMI/USB-C (video) signal input.
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 4:3 nor 16:9 and you want
to make the most use of the screen without altering the
image's aspect ratio.
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.
16:9
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.
16:10
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.
