Mitsubishi Electronics user manual Selecting the aspect ratio, EW270U EX240U

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 / until the DISPLAY menu is highlighted.

2.Press to highlight Aspect Ratio.

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

	movies, as it displays them without aspect alteration.

3.Real: The image is projected as its original resolution, and resized to fit within the display area. For input

signals with lower resolutions, the projected image will
display smaller than if resized to full screen. You could
adjust the zoom setting or move the projector towards

the screen to increase the image size if necessary. You
