Switching input signal

The projector can be connected to multiple devices at the same time. However, it can only display one full screen at a time. When starting up, the projector automatically searches for the available signals.

Be sure the Quick Auto Search function in the SOURCE menu is On if you want the projector to automatically search for the signals.

To select the source:

1.Press SOURCE on the projector or remote control. A source selection bar displays.

2.Press / until your desired signal is selected and press MODE/ENTER.

Once detected, the selected source information will display at the corner of the screen for seconds. If there is multiple equipment connected to the projector, repeat steps 1-2 to search for another signal.

•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 native display resolution of this projector is in a 4:3

(MX818ST/MX819ST)/16:10 (MW820ST) aspect ratio. For best display picture results, you should select and use an input signal 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 26 for details.

Changing Color Space

In the unlikely event that you connect the projector to a DVD player via the projector’s HDMI input and the projected picture displays wrong colors, please change the color space to YUV.

To do this:

1.Press MENU/EXIT and then press / until the SOURCE menu is highlighted.
