You can also press repeatedly until it is restored to the original size. The picture can only be navigated after the picture is magnified. You can further magnify the picture while searching for details. 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, which is the default for this projector, 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. Press / to select an aspect ratio to suit the format of the video signal and your display requirements. About the aspect ratio In the pictures below, the black portions are inactive areas and the white portions are active areas. OSD menus can be displayed on those unused black areas. 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 16:10 picture use of the screen without altering the image's aspect ratio. 15:9 picture 2. 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 4:3 picture to full screen. You could move the projector towards the screen to increase the image size if necessary. You may also need to refocus the projector after making these adjustments. 16:9 picture 3. 4:3: Scales an image so that it is displayed in the center of the screen with a 4:3 aspect ratio. [. . . ] Select the correct input signal with the Source key on the projector or remote control. Open the lens cover. Blurred image Cause The projection lens is not correctly focused.
