This function is only available when PC D-Sub input signal (analog RGB) is selected.
It is recommended that you display a bright image when performing this function.
Fine-tuning the image 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 select an image ratio that suits your need (no matter what aspect the source is), you can
follow one of the following steps.
• Press Aspect repeatedly.
•Go to the DISPLAY > Aspect Ratio menu and press Enter. Press / to select an
aspect ratio to suit the format of the video signal and your display requirements.
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: 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. 2.35:1: Scales an image so that it is displayed in the center of the screen with a 2.35:1
aspect ratio. This is most suitable for images which are already in a 2.35:1 aspect, as it
displays them without aspect alteration.
1. Adjust the projected image to the size
that you need using the zoom ring.
2. If necessary, sharpen the image by rotating
the focus ring.
