Setting up
Connecting your devices (continued)
• Be sure to read the manuals for devices before connecting them to the 
projector, and make sure that all the devices are suitable to be connected with this 
product. Before connecting to a PC, check the signal level, the signal timing, and the 
resolution.
-   Some signal may need an adapter to input this projector.
-   Some PCs have multiple screen display modes that may include some signals which 
are not supported by this projector. 
-    Although the projector can display signals with resolution up to UXGA  (1600X1200), 
the signal will be converted to the projector’s panel resolution before being displayed. 
The best display performance will be achieved if the resolutions of the input signal and 
the projector panel are identical.
• While connecting, make sure that the shape of the cable's connector fits the port to 
connect with. And be sure to tighten the screws on connectors with screws.
• When connecting a laptop PC to the projector, be sure to activate the PC’s external 
RGB output. (Set the laptop PC to CRT display or to simultaneous LCD and CRT 
display.) For details on how this is done, please refer to the instruction manual of the 
corresponding laptop PC.
• When the picture resolution is changed on a PC depending on an input, automatic 
adjustment function may take some time and may not be completed. In this case, 
you may not be able to see a check box to select “Yes/No” for the new resolution on 
Windows. Then the resolution will go back to the original. It might be recommended to 
use other CRT or LCD monitors to change the resolution.
• In some cases, this projector may not display a proper picture or display any picture on 
screen. For example, automatic adjustment may not function correctly with some input 
signals. An input signal of composite sync or sync on G may confuse this projector, so 
the projector may not display a proper picture.NOTE

equipment (i.e. display devices). This projector is VESA DDC 2B compatible. Plug-and-
