[. . . ] 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 adjust the zoom setting or move the projector towards the screen to increase the image size if necessary. You may also need to refocus the projector after making these 16:9 picture adjustments. 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 4:3 picture monitors, standard definition TV and 4:3 aspect DVD movies, as it displays them without aspect alteration. Operation 31 3. 4. 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 16:9 picture without aspect alteration. Optimizing the image Selecting a picture mode The projector is preset with several predefined picture modes so that you can choose one to suit your operating environment and input signal picture type. To select a operation mode that suits your need, you can follow one of the following steps. · Press Mode/Enter on the remote control or projector repeatedly until your desired mode is selected. Go to the PICTURE > Picture Mode menu and press / to select a desired mode. · Picture modes for different types of signals The picture modes available for different types of signals are listed below. PC input signals: D-Sub / Comp. Dynamic mode (Default): Maximizes the brightness of the projected image. This mode is suitable for environments where extra-high brightness is required, such as using the projector in well lit rooms. The brightness is emphasized in this mode to match PC and notebook coloring. sRGB mode: Maximizes the purity of RGB colors to provide true-to-life images regardless of brightness setting. It is most suitable for viewing photos taken with an sRGB compatible and properly calibrated camera, and for viewing PC graphic and drawing applications such as AutoCAD.
