signals.
You can also manually cycle through the available input sources.

•The brightness level of the projected image will change accordingly when you switch between different input signals. Data (graphic) "PC" presentations using mostly static images are generally brighter than "Video" using mostly moving images (movies).
The input signal type effects the options available for the Picture Mode. See "Selecting a picture mode" on page 33 for details.
•The native display resolution of this projector is in a 4:3 aspect ratio. For best display picture results, you should select and use an input source which outputs at this resolution. Any other resolutions will be scaled by the projector depending upon the 'aspect ratio' setting, which may cause some image distortion or loss of picture clarity. See "Selecting the aspect ratio" on page 32 for details.

Please change to an input signal which is compatible with the projector's resolution or set the input signal to a lower setting. See "Timing chart" on page 59 for details.
