The Aspect Ratio is the ratio of the image width to the image height.

Display Mode Aspect Ratio Auto Brightness 50 Contrast 50 Tint 0 Saturation 50 Sharpness 12 Gamma Alpha Color Temp Reset

Display Mode Aspect Ratio Auto 4.3 14.9 16.9 Native

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.

Menu Option Description
Aspect Ratio	16:9Scales 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.NativeDefault aspect ratio.
Brightness	The higher the value, the brighter the image. Lower values will result in a darker image.
Contrast	Use this to set the peak white level after you have previously adjusted the Brightness setting to suit your selected input and viewing environment.
Tint	The higher the value, the more greenish the picture becomes. The lower the value, the more reddish the picture becomes.
Saturation	Refers to the amount of that color in a video picture. Lower settings produce less saturated colors; in fact, a setting of “0” removes that color from the image entirely. If the saturation is too high, that color will be overpowering and unrealistic.
Sharpness	A high value results in a sharper picture; a low value softens the picture.
