Selecting the aspect ratio

Selecting the aspect ratio

The 'aspect ratio' is the ratio of the image width to the image height. Most analog TV and computers are in 4:3 ratio, and digital TV and DVDs are usually in 16:9 ratio.

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.Press MENU/EXIT and then press About the aspect ratio / EW270U until the DISPLAY menu is highlighted.

2.Press EX240U to highlight Aspect Ratio.

3.Press Manual background / Manual background to select an aspect ratio to suit the format of the video signal and your display requirements.
